Diamond saw blade diamond segment is the work of the subject. Diamond saw blade is composed of diamond and saw blades matrix binding agent, diamond is a superhard material, play the role of the cutting edge, diamond matrix binders play a fixed role, the elemental metal powder or metal alloy powder composition, the composition is called different formulations depending on the purpose, type of formulation and diamond. Diamond blade binder phase should be how to choose it?
Depends not only on the masonry blades performance of the blade diamond, but on the diamond and the binder with the appropriate head of this composite material composed of the overall performance. For marble and other soft stone, head of the mechanical properties required is relatively low, the choice of copper-based binder. The sintering temperature is low but the copper-based binder, strength, low hardness, high toughness, low bonding strength with the diamond. When adding tungsten carbide (WC), the WC or W2C to as a skeleton metal, with the amount of cobalt in order to improve the Edge Pads strength, hardness and binding properties, and add a small amount of low melting point and low hardness Cu, Sn, Zn and other metal for bonding phase. Main plus ingredients should be finer than 200 mesh size, add ingredients finer than 300 mesh size should be.

natural diamond use
Natural diamond tools currently used mainly for copper and copper alloys and gold, silver, rhodium and carbide grinding wheels other precious metals, and special parts of the ultra-precision mirror processing, such as a disk recorder, an optical mirror, a polygon mirror and the second curved mirror and so on. But its crystalline anisotropy, the tool expensive. PCD performance depends on the content of diamond grains and cobalt, cemented carbide tool life (WC substrate) of the tool 10 to 500 times. Mainly used for a variety of non-ferrous metals such as turning of aluminum, copper, magnesium and wet polishing pad its alloys, tungsten carbide and wear strong fiber reinforced plastic materials, metal matrix composites, wood and other non-metallic materials. When cutting speed, feed rate and depth of cut depends on processing conditions and the hardness of the workpiece material. Synthetic polycrystalline diamond compact (PDC) properties and applications close PCD tool, mainly used in non-ferrous metals, tungsten carbide, ceramics, non-metallic materials (plastic, hard rubber, carbon rod, wood, cement products, etc.), composite materials such as cutting, gradual replacement carbide cutting tools. Because the diamond particles bonded to ask some residual metal and sanding paper graphite, in which the bonding metal or showed coalescence vein-like distribution state will reduce tool wear and life. In addition there is a metal residue solvent, solvent metal in direct contact with the diamond surface. Lower (PDC) oxidation resistance and tool heat resistance, the cutting tool is not stable enough. Thick Diamond Tool preparation process is complex, because of the low melting point metals and their alloys and diamond has a high interfacial energy between. Diamond is difficult to be generally low melting point solder alloy infiltration. Weldability poor, difficult to produce complex geometry tool, it can not be applied TDF welding tool in high-speed milling. Diamond-coated tools can be applied to high-speed machining, because in addition to diamond coated tools have excellent mechanical properties, diamond coating process can be prepared any complex shape cutters for high speed machining aerospace materials such as aluminum alloy and refractory processing of non- metallic material such as graphite electrodes.

Stone Tips: What are the differences granite with marble
Central Plains and some natural marble crustal rocks through the crust to form high temperature and pressure metamorphic rocks. Belong to the hard stone, mainly composed of calcite, limestone, serpentine and dolomite. The main components mainly calcium carbonate, about 50% or more. Others diamond tools manufacturerinclude magnesium carbonate, calcium oxide, manganese oxide and silica. Because marble is generally contains impurities and calcium carbonate by the carbon dioxide in the atmosphere, carbon, water and gas, and may also easily weathering and dissolution, leaving the surface quickly lose luster. So few, such as marble, Ai Ye and other diamond wire saw pure quality, less impurity, more stable and durable varieties can be used outdoors, other species should not be used outdoors, generally used only for interior surfaces.
Can be made of natural marble veneer senior decoration works for hotels, exhibition halls, theaters, shopping malls, libraries, airports, railway stations and other public construction projects within the interior walls, to the surface, railings, floors, window panels, service Taiwan, elevators Menlian finishes, are ideal indoor senior decoration materials. They also can be used to produce marble murals, crafts, household items and so on.
Natural Granite is igneous rock, also called acid crystals plutonic igneous rock is the most widely distributed as a rock, is a hard stone, of feldspar, quartz and mica, whose composition of silica-based, accounting for about 65% ~ 75%. Rock hard dense, crystalline particles according to their size can be divided into "pegmatite", "coarse-grained" and "fine grain" three.
Granite depends on the quality of the turbo diamond blade mineral composition and structure. High quality granite, fine and uniform crystalline particles, mica and quartz content of less more, and does not contain pyrite. Granite difficult to weathering deterioration, appearance and color can be maintained more than a century, so much for the foundation and exterior wall finishes. Because granite hardness, wear resistance, it is also commonly used in high building renovation projects, such as the lobby floor.
As compared to granite and marble texture harder and acid, and thus in home decoration is more suitable for outdoor balcony, patio, dining room, floor and window sill. The marble can be used for bar, cooking sets, sideboard countertops.

Classification and characteristics of
Granite formation conditions as ingredients to form complex and diverse, so the variety, there are a variety of classification. Sub-divided according to types of minerals contained in black tile saw blade granite, muscovite granite, hornblende granite, two-mica granite. Constructed according to the structure can be divided into fine-grained granite, medium-grained granite, coarse-grained granite, porphyritic granite, porphyritic granite, geode granite and gneissic granite. Press contain minerals can be divided into cassiterite granite, niobium ore granite, granite containing beryllium, lithium mica granite, tourmaline granite. Common length petrochemical, greisenized, electrical and petrochemical since metamorphism.Granite compact structure, high compressive strength, low water absorption, surface hardness, good diamond core drills chemical stability, durability, fire resistance, but poor. Granite was fine, the grain, coarse granular structure, or porphyritic structure, fine uniform particles, the gap is small (porosity of 0.3% to 0.7%), water absorption is not high (water absorption is generally 0.15 % ~ 0.46%), with good frost resistance. High hardness of granite, its Mohs hardness of about 6, a density of 2.63g/cm3 to 2.75 g/cm3 in between, the compression strength of 100-300MPa, in which fine-grained granite up to 300MPa or more, flexural strength Average at 10 ~ 30Mpa. Often granite batholith, rock plants, rock and green concrete blades other forms of output, and is subject to regional tectonic control, generally larger than the size distribution is relatively broad, so mining convenient, easy out aniseed, and its joint development with the law, help shape the rules mined stone. Shortage of granite into high, can carry a variety of machining, sheet metal can fight good. There weathered granite is not easy, I can do outdoor decorative stone. Granite texture uniform texture, color, although dominated by light colors, but also very rich in red, white, yellow, green, black, purple, brown, beige, blue, etc., and relatively little change in its color, suitable for large the area of use.

selected tool efficiency principle
Do the cutting tool industry should be carried out to buy, many businesses usually do not know what to buy a good tool material, diamond tool manufacturers say in metal cutting, tool selection process engineer almost every one must face the problem.
Tool selection to consider many wet diamond polishing pads issues, and accordingly there are many principles such as the principle of efficiency, precision principles, stability principle, the principle of economy and so on.
Let me first explain the principle of efficiency. Efficiency principles are in fact inseparable with other principles, especially the principle of economy. The main purpose of the efficiency requirement is to ensure that the economy of the entire process. But efficiency is particularly important, so it independent, separately discuss the issue.
The first is the principle of efficiency in maintaining acceptable precision and stability acceptable under the premise of efficiency. Without this basic condition, the efficiency of the question. Just as we want our vehicles (such as cars) can bring us more speed, but safety comes first. Once after the crash, many people will seriously consider whether you really continue to choose air travel, the airline will re-examine the existing security policy. Without security, the aircraft would not have become the preferred means of transport. Tool selection same.
Secondly, we do not at all emphasize efficiency under all conditions, the pursuit of efficiency has some constraints. A part machining efficiency and other parts required to adapt the turbo diamond blade efficiency, improve the efficiency of a process and other processes need to adapt efficiency. If you ignore these constraints, the blind pursuit of efficiency, will be a thankless task. As the train from Shanghai to Beijing, and now start around 20:00 the next morning 10:00 to arrive. If you can advance to the 8:00 arrived, perhaps the most popular; But if advance to the 6:00, maybe popularity decreased. Because the conductor in advance before arriving an hour or two hours finishing travelers bed in the morning 4:00 or 5:00 to get up the majority of visitors will not be too willing. Plant is true, in particular, especially in the production line conditions. We need to address the entire pipeline "bottleneck" processes. As long as the increased production capacity of this process, we can improve the whole production line capacity, improve the production capacity, shorten the manufacturing cycle, which is the desired number of companies. The stand-alone or flexible manufacturing system needs not the same. They suffered less constrained, ie processes associated with other smaller degree. Because flexible, a part or a process to shorten the manufacturing cycle often means being able to make other parts of the device is put into production or other processes, thereby creating more benefits.
In today's increasingly competitive market, business process engineer's expectations is not a simple process to solve the problem, but the expectations of the enterprise process engineers were able to have a greater contribution. If our process engineers from the diamond tool manufacturer overall situation of enterprises, improve the manufacturing processes for enterprises to contribute to business owners will get the approval and praise.
Modern metal processing enterprises on foreign survey data, the manufacturing cost of the tool itself is not very high proportion, usually in the 2% to 4%, and the high will go to about 7%. However, the impact on the efficiency of the tool is very huge. A few hundred thousand dollars worth of equipment can play its due role, often depends on a few dollars a tool. I've got over a cost analysis examples show that 30% of the purchase price reduction (mean no change in tool performance) or 50% longer tool life (usually relies tool manufacturer's technical progress) can only reduce manufacturing costs a percent? because tool costs account for only 4% of the total manufacturing cost. But if the process parameters can be increased by 20%, about 15% can reduce manufacturing costs?? Although if the cutting speed is increased by 20%, the tool costs increased by 50%, but because of processing cycles, the total cost is still a significant decline.

the carbide circular saw blades
The actual selection of circular saw blades sawing to consider is the type of material thickness, cutting speed, cutting direction, feed rate, saw the road width and other masonry saw blades specific issues. These problems ultimately attributed to the saw blade tooth, angle and other parameters of selection, the following parameters for the blade geometry make a brief introduction:
1, saw tooth choices
Tooth circular saw blade is divided into left and right teeth, conical teeth, flat teeth, trapezoidal tooth, crescent-shaped teeth, etc., the actual use based primarily on the type of material to be sawn to choose.
① around teeth for open bar and crosscut saw all kinds of soft and hard wood and particleboard, equipped with anti-rebound protection around the tooth for tooth longitudinal cutting various sections of the plate with trees, with a negative rake angle of the saw teeth around piece due sharp serrated, cutting good quality, usually used plywood sawing.
② conical teeth commonly used in the grinding cup wheel groove panel saw blade, in the double sawing plywood veneer, the groove bottom grooving saw the completion, the main plate sawing sawn finish to prevent the collapse occurred Jukou ballast phenomenon.
Flat teeth mainly used for general cutting of wood, this blade low cost, but rough saw cut.
③ trapezoidal tooth peace teeth used in combination unworthy groove sawing blade also get a higher quality when cutting veneer crack phenomenon does not occur for a variety of dual-veneer plywood sawing.
2, the choice of jagged angles
Angle parameter serrated portion is complex, and the sand paper correct choice of the blade cutting angle parameter is to determine the quality of the key. The main point of argument is the rake angle, clearance angle, wedge angle.
Rake angle sawing wood consumed by the main impact force. Serrated cutting rake angle greater sharpness better, more portable sawing, pushing more effort. Generally relatively soft material to be processed, the selected larger rake angle, otherwise choose a smaller rake angle.

diamond cutter end milling milling asymmetry
Asymmetrical diamond milling milling cutter, milling parts accounted for a larger proportion of each tooth milling cutter force in the feed direction, the force in the direction opposite to the core drill bits feed direction, do not pull the table, and the blade cut Although artificial parts when chip thickness from thin to thick but not to zero, and thus impact, vibration is also smaller. Therefore, end milling milling asymmetry should be taken. Water jet machining technique of diamond cutting tools is the use of pressurized water to a hydraulic system 200 to 600MPa, the high-pressure water through a special design of the small diameter (0.076 a 0.635mm) the outlet, the formation of the beam about three times the speed of sound diamond tool , the granite polishing pad impact surface of the material to be processed and removing a portion of material. According to whether the water mixed with abrasive water jet cutting technology is mainly divided into pure water jet · (Wi) and abrasive water jet (AWJ) machining two categories. The former is mainly used for cutting non-metallic materials, rust removal and decontamination, which is mainly used for metal and composite materials, and some can not be processed by conventional methods or processing of the more difficult situations.Water jet and abrasive water jet machining technology theory behind its applied research, the industrial saw blades results of many practical applications, in theory, still can not make a sound explanation, water and energy transfer between the abrasive possible through a variety of ways, and the more complex ; generally believe that the speed of the water jet cutting of materials can play a decisive role.
Experimental and theoretical analysis that the water jet at high speed diamond tools for the vortex forms its central and peripheral role in the vortex without constant. Equal to the average maximum flow velocity and peripheral velocity and the minimum flow rate is the average flow velocity and peripheral velocity difference. High speed jet hit the target form vortex structures, its high-speed part of the longitudinal elastic coefficient of the fluid increases, the rigidity increases. When this rigidity is greater than the target, the target will be the impact of being crushed, which produce cutting target role. When the low part of the hit target, its fluid longitudinal elastic coefficient, rigidity is small, similar to the soft material and the role of material to be cut, sometimes negative velocity can be crushed by debris sucked.

diamond is difficult to geometries Tool
Diamond Tool preparation process is complex, because the diamond between the low-melting metals and their alloys have a high interfacial energy. Diamond is difficult to be generally low melting point solder alloy infiltration. Weldability poor, difficult to produce complex geometry tool, it can not be applied TDF welding tool in high-speed milling.
Natural diamond tools currently used carbide grinding wheels mainly for copper and copper alloys and gold, silver, rhodium and other precious metals, and special parts of the ultra-precision mirror processing, such as a disk recorder, an optical mirror, a polygon mirror and the second curved mirror and so on. But its crystalline anisotropy, the tool expensive. PCD performance depends on the content of diamond grains and cobalt, cemented carbide tool life (WC substrate) of the tool 10 to 500 times. Mainly used for a variety of non-ferrous metals such as turning of aluminum, copper, magnesium and its alloys, tungsten carbide and wear strong fiber reinforced plastic materials, metal matrix composites, wood and other non-metallic materials. When cutting speed, feed rate and depth of cut depends on processing conditions and the hardness of the workpiece material. Synthetic polycrystalline diamond compact (PDC) properties and applications close PCD tool, mainly used in non-ferrous metals, tungsten carbide, ceramics, non-metallic materials (plastic, hard rubber, carbon rod, wood, cement products, etc.), composite materials such as cutting, gradual replacement carbide cutting tools. Because the diamond particles bonded to ask some residual metal and graphite, in which the bonding metal or showed coalescence vein-like distribution state will reduce tool wear and life. In addition there is a metal residue solvent, solvent metal in direct contact with the diamond surface. Lower (PDC) oxidation resistance and tool heat resistance, the cutting tool is not stable enough. Diamond-coated tools can be table saw blades applied to high-speed machining, because in addition to diamond coated tools have excellent mechanical properties, diamond coating process can be prepared any complex shape cutters for high speed machining aerospace materials such as aluminum alloy and refractory processing of non- metallic material such as graphite electrodes. Vitrified diamond grinding wheel with diamond and vitrified common characteristics, and general corundum, silicon carbide abrasive compared to its strong grinding, grinding temperature is relatively low, abrasive wear is relatively small; can be adapted to a variety of The role of the cooling fluid; grinding abrasive good shape retention, high precision grind the workpiece; abrasive there are more pores, grinding and heat conducive chip, clogging, easy to burn the workpiece; mill with good self-sharpening, finishing a long time interval, trimming easier. Therefore, vitrified diamond grinding wheel used hole saw blades in some foreign countries is increasing. Select reasonable parameters, vitrified diamond wheel grinding single crystal diamond, grinding efficiency than metal bonded grinding wheel high, wear ratio is very small, low cost, so the use of ceramic bonded grinding wheel grinding single crystal diamond, can greatly improve Happening grinding efficiency. PCD tools in the grinding, since the binder resin is relatively soft, easily deformed when grinding, grinding of PCD tools can not be effectively; metal bonded abrasive due to too strong binding ability of leaving the poor self-sharpening abrasive, grinding low efficiency, and metal bonded grinding wheel will cause the edges of PCD tool most serious damage; integrated grinding efficiency, durability and abrasive machining the workpiece surface quality vitrified diamond grinding wheel PCD tool is the most appropriate choice.

affect the diamond tool wear What are the reasons
Regardless of no matter how good things are bad when the diamond tool is also the case, diamond cutter hard, along with the use of time can be delayed, there will be some diamond tool wear, tool wear effect for several reasons, what does?
The more rigid tool material, the concrete saw blades better the wear resistance, the higher the hardness, the lower the impact toughness, the material is brittle. Hardness and toughness is a contradiction, but also the tool material that should overcome a key. For graphite tools, common tialn coating can be selected in the selection of the appropriate point relatively good toughness, which is slightly higher cobalt content; tool for diamond-coated graphite, can be selected in the selection of the appropriate hardness relatively good point , which is slightly lower cobalt content;
Diamond-coated tools, high hardness, wear resistance, and low coefficient of friction, at this stage diamond-coated graphite machining tool is the best choice, but also the tool that best reflects the superior performance of graphite; diamond-coated rigid alloy tool combines the advantages of natural diamond carbide hardness and strength and fracture toughness. Also using the world's most advanced coating technology for surface treatment of the tool, in order to ensure that the processing life while ensuring the economic and practical tool.
Every machining practitioners are hoping to improve tool life. Now the main processing tool uses a graphical display production efficiency and abrasion scratch depth (VB) with the growth of the service life of the process of gradually deepened.
If you need to wear frequently record the formation process of the formation mechanism of wear and tear on the green concrete blades need for a new system. High-definition digital camera (8,000,000 pixels) equipped with an optical image stabilizer, a newly developed micro sight and accessories source. Magnetic tripod joint bracket as a mobile, and can be directly fixed on the machine. If you need to optimize the process, the entire system can be placed in a portable container and equipped with the necessary spare battery, charger, or cleaning appliances. Measurement system configuration: direct dial milling cutter in front furnished with a magnetic tripod digital camera.
Measurement process is as follows: a digital camera mounted on a tripod in the magnetic, turn on the camera and light source, will be fixed in the tool near (± 2mm), and use auto focus fast imaging. The wet core bits use of magnetic tripod can also be measured directly on a milling machine, or from the stand without having to remove the tool spindle. Digital cameras can be rotated with the screen, you can shoot at any position.

what the DTH Bits Use
In order to properly use the drill hole, drill drilling speed and guarantee period of use, the following points should be noted:
1, according to the rock condition (hardness, abrasion resistance) and rig type (high pressure, low pressure) to select the drill hole. Different forms of alloy teeth and tooth arrangement method is applicable to different rock drilling. Choosing the ceramic tile saw right drill hole, is a prerequisite to obtain the best results;
2, the installation DTH drill bit to drill gently into DTH hammer drill kit card, do not force the collision, to avoid damage to the caudal peduncle or card drill bit sets;
3, in the drilling process, to ensure that the pressure submersible drilling rig air pressure is sufficient. If there impactor intermittent work, or poor borehole ranked powder should be checked submersible drilling rig compressed air system to ensure no rocks hole drilling process slag;
4, if found metal objects fall into the table saw blades hole in the magnet should be promptly sucked out or removed by other means, so as to avoid damage to the drill bit;
5, replace the drill bit to the attention of the blast hole drilling good size. If excessive wear of the drill diameter, but not yet drilled hole when the gun can not be replaced with new drill to avoid sticking. May have been used and worn with a diameter substantially the same as the old drill complete the job;
6, for the emergence of early non-normal retirement DTH drill bit, shall promptly notify the company to notify the dry cut blades contents include:
1), rock type and construction sites;
2), supporting the use of the impactor model;
3), drill failure modes (broken teeth, lost teeth, drill head collapse block, drill caudal fracture);
4), bit life (number of meters have been drilled footage);
5), the number of failures drill;
6), the normal use of a few meters drill footage
Type of drill
Is the most widely-hole machining tool. Diameter range of usually 0.25 to 80 mm. It is mainly the working portion and the shank by the drill portion. Working part has two spiral grooves, the dry polishing pads shape of cannabis, hence the name. In order to reduce drilling holes intramural guide portion and the friction, twist drill tip to the shank from the direction of decreasing diameter inverted cone. Helix angle of twist drill cutting edge came principally affected the size of angles, edge flap strength and chip performance, typically 25 ° ~ 32 °. Available spiral groove milling, grinding, hot-rolled or hot extrusion processing methods, the drill bit tip is formed by grinding after the cutting portion. Standard twist angle of the cutting portion 118, a horizontal blade angle is 40 ° ~ 60 °, after the angle of 8 ° ~ 20 °. For structural reasons, a large rake angle in the outer edge, and gradually decreases toward the center, horizontal blade at a negative rake angle (up to about -55 °), when drilling from the compression. In order to improve the cutting performance of twist drills, according to the nature of the material to be machined part will repair ground cutting various shapes (such as drilling group). Form of shank twist drill straight shank and taper shank are two processing caught in the drill chuck the former, the latter inserted in the machine spindle or tailstock taper hole. Generally high-speed steel twist drill. Inserts welded carbide blade or twist the crown for machining cast iron, hardened steel and non-metallic materials, solid carbide twist drills for machining small parts and printed circuit boards and other instrumentation.
Flat drill
Cutting portion of the industrial saw blades drill flat spade, simple structure, low cost, easily cutting fluid into the hole, but the cutting and chip performance is poor. Flat structure integral drill and assembly two. Integral mainly for drilling diameter of 0.03 to 0.5 mm pores. Fabricated flat diamond blade can be changed, can be cooled, mainly for the drilling diameter 25 to 500 mm large hole.
Deep hole drilling
Deep hole drilling is typically the machining hole depth is greater than the diameter of the bore of the tool 6. Commonly used gun drilling, BTA deep hole drilling, jet drill, DF deep hole drilling. Nesting also used in drilling deep holes.
Reamer
Reamer has three to four teeth, better rigidity than the twist, to expand the existing hole and improve the machining accuracy and finish.
Countersink
Countersinks have more teeth to the end of the stone polishing pads hole forming method processed into the desired shape, for processing a variety of countersunk head screws countersunk holes, holes or flattened outer end face.
Center drill

carbide drill considerations
Selection of carbide drill, you first need to consider the size of drilling accuracy requirements. Generally, the smaller the aperture is processed, a tolerance is smaller. Therefore, manufacturers usually drill the hole to be processed according to the nominal diameter of the drill bit segments. In the above four types of carbide drills in solid carbide drill highest precision (φ10mm solid carbide drill tolerance range is 0 ~ 0.03mm), so it is the best choice for machining precision holes; welded carbide replaceable carbide drill or drill crown tolerance range is 0 ~ 0.07mm, more suitable for general accuracy of hole machining; installation carbide indexable insert drill is more suitable for heavy roughing, Although its processing cost is generally lower than several other bits, but its precision is relatively low, the carbide grinding wheels tolerance range is 0 ~ 0.3mm (depending on the aspect ratio bits), so it is generally used for hole machining accuracy is not required , or by dress finished hole boring finishing blades.
(2) processing stability
In addition to considering drilling accuracy requirements, the need to consider when you select the drill machine tool stability. Machine stability and service life for the safety drill drilling accuracy is essential, therefore need to carefully examine the machine spindle, fixtures and accessories working condition. Also, consider the stability of the drill itself. For example, the overall rigidity of the best carbide drill, so you can achieve very high precision. The carbide indexable insert drills structural stability is poor, prone to deflection. This bit is installed on two indexable inserts, inserts for machining holes in which the inner central portion of the processing of the outer blade at the outer diameter from the inner to the outer periphery of the blade portion. Since the initial stage in the processing of only the inner blade into cutting, drilling in an unstable state, can easily cause the drill body deflection, and the drill bit longer, the greater the amount of skew. Therefore, the use of longer than 4D carbide indexable insert drills for drilling, the drilling phase at the beginning should be appropriate to reduce the feed rate, cutting into the stable phase after the feed rate to normal levels . Welded carbide replaceable carbide drill bit and drill crown is composed of two symmetrical cutting edge geometry may be self-centering blade type, which has a high stability of the cutting edge designed to cut into the workpiece without reduce feed rate, and only when the bandsaw blades bit inclined installation into a certain angle with the surface of the workpiece when cutting exception, this time recommended drill, drill feed rate will decrease from 30% to 50%. Because these drill steel drill body can produce small deformation, making it ideal for lathe; rather brittle solid carbide drills due for lathe machining easier to break, especially when the centering drill bit in poor condition This is especially true.
3 Chip and Coolant
BTA is drilling problems can not be ignored. In fact, most drilling encountered problem is poor chip removal (machining mild steel workpiece is especially true), and regardless of drills were unable to avoid this problem. Processing plant are often used outside the way into the auxiliary coolant chip, but this method only in the machining hole diameter and reduce the cutting depth is less than the case where parameters are valid. In addition, you must use the drill diameter to match the proper coolant type, flow and pressure. For the cooling system is not installed on the machine tool spindle, you should use coolant ducts. The deeper the hole to be machined, chip more difficult and requires the greater the pressure of the cooling fluid, should be recommended by the manufacturer of drill minimum coolant flow, such as cooling liquid flow rate is insufficient, the need to reduce the machining feed rate.
4 processing cost per hole
Productivity or each hole drilling processing costs affecting the most important factor. In order to improve productivity, drill manufacturers are working on a variety of operating processes can be integrated processing methods and the development to achieve high feed, high speed processing of the drilling tool.
The newly developed replaceable carbide drill crown has excellent machining economy. Bit wear, the user does not have to replace the entire drill body, you can simply replace the carbide tooth crown, and its purchase price is equivalent to welded or solid carbide drill regrinding a fee. Carbide crown replacement is easy and repeatable high precision, machine shop can drill body with a plurality of teeth crowns, to the processing of different pore size holes. This modular drilling system can be reduced 12 ~ 20mm diameter drill cataloging costs, but can also save on welding or grinding of solid carbide drills need to re-backup tool costs.
In considering the processing cost per hole, the total lifetime of the drill should be counted. Generally speaking, a solid carbide drill regrinding only 7 to 10 times, a welded carbide drill regrinding only 3 to 4 times, and replaceable carbide drill crown in the processing of steel material When the steel of the drill body can be replaced at least 20 to 30 times the crown.
As welded or solid carbide drills need to re-grinding, in order to avoid tool breakage, workshops in the wet tile saw use of such drills tend to use lower cutting parameters, thus also affect drilling productivity. The replaceable carbide drill crown without regrinding, the workshop can be used in the processing of the largest feed rate and cutting speed without having to worry about damage to the crown.
In many cases, the solid carbide drill or welding after regrinding of the cutting edge shapes and edge processing state is difficult to completely match with the new drill bit, so the cutting is some difference with the new drill. In addition, if re-grinding process of the cutting edge mishandled may easily damaged blade, drilling torque and increased drilling force, cutting heat increase, leading to drill shortened life expectancy. While the new replaceable carbide drill life of the crown is more consistent.

circular saw blade dynamic
Dynamic operation stability of the circular saw blade is a blade in the cutting processing, maintaining its inherent shape and stiffness properties. Job stability than the saw blade and the frame band saws poor, mainly because of large blade diameter to thickness ratio, and only the clamping disc holding the spindle rotates at high speed can not be tensioned. Part of the body alone saw serrated metal binding force, it maintains a certain rigidity. When the blade rotates at high speed, the centrifugal force, the grinding wheels saw tooth edge portion of the body begins to relax, in addition, timber sawing, the saw tooth edge portion of the body temperature rise sharply, volume expansion, and the blade but also by material constraints can not be arbitrarily scalable, large internal deformation occurring outside the small, on both sides of the blade to swim, was "hunting" state, causing rough sawn wood surface waves.
First, the centrifugal force
Rotating blade, the saw body parts of the material are subject to the centrifugal force.
Second, the impact of cutting heat and displacement caused by temperature gradients
Saw cutting work, saw tooth edge portion of the industrial saw blades body temperature is higher than the temperature of the rest of the blade on the outside there is a high internal temperature low, according to Mote, Szymani other scientists' research results, for the 1mm thick blade, When the blade in the radial direction of the temperature difference reaches 9 ℃, the blade wavy deformation occurs. Also exacerbated instability in the blade work.
Third, the circular saw cutting runout and lateral vibration on Processing Quality
Cutting circular saw blades, due to the number of teeth and more, chip thickness of only hundredths of a millimeter. So rather small radial deviation will be on chip thickness have a great impact, in addition to radial runout effects, the lateral vibration of the processing quality, especially surface roughness has a great influence.
Four, vibration analysis
Vibration of the saw blade is in its equilibrium position the blade reciprocating lateral movement. Vibration caused by external interference, and always behave as some kind of "class." Vibration of the blade during cutting can not be compensated, the vibration will increase sawing path loss, reduced cutting accuracy, increase the noise level and shorten tool life.
Fifth, the concept of stability
Saw work there is always a certain vibration, but not necessarily instability. The critical instability conditions, even if a frequency is zero or very small lateral forces can cause very large lateral displacement of the blade. Instability saw blade vibration theory is the stone polishing pads study of the most important fields.
Six, critical speed theory
Theoretical critical speed is determined by Lapin and Dugdale introduced into the study of circular saw blades, before this theory is mainly used in the design of turbine research.
Seven, plane stress
The initial blade manufacturing residual stress include stress, suitable for tensile stress. Rotary cutting blade, will turn with stress, thermal stress and the stress caused by cutting force. All of these stresses can be considered as plane stress.

First, the centrifugal force
Rotating blade, the saw body parts of the material are subject to the centrifugal force.
Second, the impact of cutting heat and displacement caused by temperature gradients
Saw cutting work, saw tooth edge portion of the industrial saw blades body temperature is higher than the temperature of the rest of the blade on the outside there is a high internal temperature low, according to Mote, Szymani other scientists' research results, for the 1mm thick blade, When the blade in the radial direction of the temperature difference reaches 9 ℃, the blade wavy deformation occurs. Also exacerbated instability in the blade work.
Third, the circular saw cutting runout and lateral vibration on Processing Quality
Cutting circular saw blades, due to the number of teeth and more, chip thickness of only hundredths of a millimeter.

diamond electroplated tools of new technology
Diamond is found in the highest hardness, sharp with good abrasive. The method
of electroplating diamond abrasive "plating out" on the metal base, instead of
the diamond saw blade traditional casting sintering, not less investment, low cost, and avoid the
oxidation of the diamond under high temperature conditions, to ensure the
hardness and sharpness of diamond.
Diamond in the whole process, the plating layer with more than 90% is due to
poor due to poor plating pre-treatment. Therefore, to improve plating quality,
the most important thing is to do pre-plated.
Pre-treatment of the general content include: degreasing, rust, etching,
pickling, cleaning and activation plus auxiliary electrode and fitted pegs.
In order to improve the coating quality, after the electroplating industry at
home and abroad were analyzed and compared with the actual, developed a new
treatment before plating process is as follows: deburring cleaning coating
thermal insulating plastic scrub chemical degreasing, pickling cold water cold
water electricity Chemical degreasing washing anodized flushed into the slot.
1 with sandpaper and hand deburring file to remove burrs on the workpiece, to
prevent the workpiece surface showing dielectric bad state.
(2) The workpiece cleaning with alcohol scrub again, initially cleared the
surface of the oil.
3 plastic insulation coating the masonry saw blades workpiece after the scrub, in the non-plated
parts coated with a layer rapid adhesive coated parts of the non-insulated.
4 To prevent the need to scrub plated parts are coated with plastic insulation,
hand file or sandpaper to polish the parts and then again, and then rinse.
5. Chemical degreasing degreasing formulations.
Sodium hydroxide has a strong saponification, and animal and vegetable oils
reacts fly soluble soap and glycerin. THF is a surface active agent call in its
hydrophobic group and a dodecyl sulfate synergy hydrophilic groups should,
lowering the liquid and the surface tension between the work. It acts as a
caustic additive accelerated degreasing speed. Sodium carbonate and sodium
silicate to place relative to the two buffer from the buffer to the acid, the
PH value of the melt remain substantially edges. The workpiece is set with the
above solution at 40 ℃ ~ 60 ℃ case of cleaning for about 30 minutes.
6 hot, cold rinse first with hot water, rinse with cold book, to avoid oil into
the acid solution in addition.
7 pickling acid liquid formulation, its purpose is to remove the oxide surface
of the substrate.
8 cold water after pickling, the workpiece clip out, rinse with cold water, and
then loaded linked to the electrochemical degreasing tank.
9 spark electrochemical degreasing degreasing formulations school
The work clothes hanging in the cbn grinding wheels solution, the connection with the point source,
the first cathode for 1 minute, 3 minutes and then anodized. The current
density used 10A/dm2, an electrode of stainless steel plate. Degreasing
electrochemical reactions are as follows:
Anode degreasing: 4OH - 2e = O2 + H2O
Cathodic degreasing: 2H + +2 e = H2
Very tired after using the first female co-degreasing method, with degreasing
speed, no hydrogen embrittlement advantages.
10 Rinse the workpiece after electrochemical degreasing sexual activity with a
book rushed into thin wash, prepare hast yang line processing.
11 anodized
Anodizing liquid formulations shown in Table 4, the substrate is mounted hung,
to be inserted into the fluid-plated parts. A negative electrode lead, the
positive electrode substrate. Current density of 25A/dm2, is applied for 3
minutes. Anodized avoid hydrogen embrittlement phenomenon, especially for the
last one into the groove before the procedure.
12. Rinsed into the slot of the anode substrate processed quickly rinsed, into
the plating tank, ready to plating.
This completes the entire diamond plating plating pre-treatment.
(Two) results
The specimen divided into five experimental groups, at various pre-plating
process under the pre-plating, and electroplating in the same plating
conditions into the slot. Specimens of each group specific treatment
conditions.
Specimen using 15152mm2 iron tablets. Experiment, the temperature was 40 ℃ 1
℃, the current density is 40MA/dm2, the anode 2 is pure nickel plate, cathode
specimen.
After the plating adhesion test pieces for both test and brittleness. Coating
adhesion test is a qualitative assay method using the rasp test. The so-called
experimental method refers rasp rasp coating from the substrate to the coating
direction 45o filing edges. If coating is not to be brought up or fall off, was
qualified.
When the binding is good, then the coating brittleness test. Brittle bending
test is used. Bending the specimen caught in the vise repeated bending, but
with a magnifying glass to observe the changes appear curved parts of the first
crack so far.
Table 5 shows the measurement results, the use of new technology, the specimen
surface smooth and good, grease and oxide are Ex, specimen showing a good state
by plating. Coating metal and the substrate has good adhesion between the
metal, coating uniformity, are better integrity.
(Three) Conclusion

workpiece surface showing the bad state of the dielectric;
(2) the sodium dodecyl sulfate as a base additive to enhance the activity of
the matrix surface, to the oil rate, good quality;
3 using low temperature to the oil, so that the substrate from heat stress;
4, after the chemical degreasing and pickling, and by electrochemical
degreasing and anodizing, greatly changed the state of the substrate surface to
improve the dispersibility of the bath and covering ability to improve the
uniformity of the coating, integrity enhance the coating adhesion.
