wood saw blades are the most commonly used wood products processing and cutting
Carbide saw blade is the most commonly used wood products processing and cutting tools, carbide saw the quality and the quality of processed products are closely related. Proper selection of reasonably carbide saw blades for improving product quality, shorten cycle times, reduce processing costs is significant. Optional carbide saw what to pay attention to? Contains tooth carbide saw blades, angle, number of teeth, blade thickness, blade diameter, carbide, etc. Most types of parameters that determine the processing capacity of GUSHI diamond polishing tools the saw blade and cutting. When you select the correct selection of the blade to blade parameters based on need.
Tooth, tooth commonly have flat teeth, Dou tooth, trapezoidal tooth, inverted trapezoidal tooth (Figure 1). Flat teeth the most widely used, mainly for ordinary wood sawing, this tooth is relatively simple, rough kerf, slotting process operating level during tooth formation can bottom. Dou teeth sawing kerf quality is better for cutting all kinds of wood-based panels, plywood. Trapezoidal tooth suitable sawing plywood, fire board, obtain higher cutting quality. Inverted trapezoidal tooth saw blade used in the bottom slot.
Zigzag zigzag angle is in the cutting position. Serrated cutting angle affects the performance results. Greatest impact is on the cutting rake angle γ, the angle α, wedge angle β. Rake angle γ is serrated cutting edge angle, the greater the cutting rake angle more brisk, rake angle generally between 10-15 °. After the angle is the angle between the machined surface of the sawtooth between its role is to prevent the serrations machined friction surface, the smaller the angle the greater the friction, the more smooth the processing products. After the general value of carbide saw blade angle 15 °. Wedge angle is derived from the anterior horn and posterior horn out (Figure 2). But the wedge angle is not too small, it plays a role in keeping the teeth, according to strength, heat resistance, durability degrees. The rake angle γ, the angle α, the wedge angle β of the three equals 90 °.
Jagged teeth, teeth more generally, the GUSHI concrete polishing pads more the cutting edge per unit time, the better the cutting performance, but required more and more carbide cutting teeth number, the price of the blade is high, but too dense serrated , the chip between the teeth becomes smaller, the heat is easy to cause the blade; sawtooth excessive addition, when the feed amount of mismatch, then cut per tooth is small, the friction will increase with the workpiece edge, the life impact of the blade . Typically tooth pitch 15-25mm, should be selected based on a reasonable number of teeth sawing material.
The thickness of the blade from the saw blade in theory, we hope the thinner the better, is actually a kerf consumption. Materials and manufacturing processes carbide saw blade sawing board determines the thickness of the blade. To consider when selecting blade thickness from work and the stability of the blade sawing materials. Diameter and thickness of the blade used for cutting and sawing equipment related artifacts. Blade diameter is small, the cutting speed is relatively low; blade diameter saw blade and GUSHI metal grinding wheel cutting equipment requirements will be higher, while cutting efficiency is high profile, angle, number of teeth, thickness, diameter, species such as a carbide combination into a whole series of parameters hard alloy saw blade, and with a reasonable choice in order to better play its strengths. Various parameters carbide saw blades should be added choose? Carbide saw blade manufacturing companies can not do so many specifications saw, according to the law and according to the current preferred specific factors wood processing enterprises equipment, materials and other components of the current series of specifications used carbide saw blades. This helps us choose carbide saw blades, but also conducive to the alloy saw blade manufacturing enterprise scale production.

Kim saw blade grinding must be noted at the time
Factor in the use of gold saw blade grinding to note about the : 1 , coolant grinding teeth grinding fluid that is good or bad decision . When a large amount of tungsten partridge grinding , diamond grinding wheel powder, not timely flushing and cleaning of the grinding wheel tool surface pores, resulting in surface grinding tool can not grind finish, there diamond blades is not enough cooling will burn alloys. 2, the grinding mechanism for grinding teeth affected. Alloy saw blade grinding machine structure and assembly that is good or bad , about the current market two types of models: one is floating in Germany Seoul ink types. The type with vertical grinding off , all the advantages of using hydraulic stepless movement , all the feed system using V -rail and ball screw work , grinding or arm using the jog feed retraction rewind, adjust the fuel tank clip heart, flexible and reliable support piece , pulling teeth accurate positioning, strong self-centering blade positioning heart , any angle adjustment , cooling rinse reasonable man-machine interface , high precision grinding off , pure grinder rational design ; II , which is currently horizontal such as Taiwan and Japan models, the presence of mechanical transmission gears and mechanical clearance dovetail slide accuracy, low steady performance clips , adjust the difficulty heart support piece , pulling teeth institution or poor reliability, after the plane left and right sides and an angle not mind grinding cut , resulting in large deviation angle difficult to control, mechanical wear disaster ensure accuracy. 3 , welding factor. Welding alloys deviation big impact precision grinding , grinding pressure while causing great pressure on the small side , rear corner also produce the above factors, the welding angle difference , inevitable human factors , all of the grinding wheel, and other factors produce an unavoidable impact . 4 , wheel width on the quality and size . Optional wheel run- gold films , pay attention to wheel size , granularity is too coarse grinding wheel produced traces wheel grinding selected fine grain size is less easy to plug , easy to burn knife. Wheel diameter and thickness is based alloy wheel width or different tooth width and the length of each side alloy case may be , not a corner after corner or front wheel can be any size as different tooth grinding , must be targeted to choose a diamond cut off wheel suitable Specifications wheel. 5 , grinding feed rate. Alloy blade grinding entirely good or bad decision grinding feed rate , generally alloy saw blade feed rate from 0.5 to 6 mm / s can not exceed this value that should be within 20 teeth per minute per minute exceeding 20 tooth feed rate is too large , it will have a serious knife tumor or burn alloy wheel produces concave surface affect the accuracy of the waste grinding wheel . 6 , grinding feed rate , the choice of wheel size on the amount of feed has very important significance. General Wheel suggested the use of 180 # 240 # 240 # to most, the choice not to choose 280 # 280 # to 320 # , or to adjust the feed rate. 7 , grinding heart. All grinding the blade and the substrate for the heart, rather than with the blade of the heart, the heart does not get out surface grinding , horn , front Dressing plates corner with a processing center can not be sharpened a blade , blade grinding three processes Heart can not be ignored . Grinding side angle still careful observation alloy thickness , thickness change with different grinding heart , no matter how the alloy thickness , surface grinding wheel center line should be kept with the welding position in a straight line , otherwise the impact of cutting angle difference . 8 , pulling teeth institutions can not be ignored . Regardless of how the structure of any grinding , pulling teeth to coordinate accuracy Brothers Design quality , acupressure pulling teeth tooth surface in a reasonable position at the time of transfer machines, and not with the move is extremely critical , when back teeth , pulling teeth jaws should flexible and reliable.

affect the life of the main factors diamond saw what
Impact efficiency and life of saw blade sawing factors are process parameters and the diamond particle size, density, hardness and other binders. It has cut the number of blades can be wire-speed, concentration Plate Compactor and cutting feedrate.One, cutting parameters(1) blade speed: In practice, the line speed diamond saw blades by equipment conditions, saw the quality and the nature of the restrictions before sawing stone. From the optimum blade life and cutting efficiency, it should be selected depending on the nature of the stone saw blade speed. Sawing granite, the blade speed at 25m ~ 35m / s within the selected range. For high quartz content and tile cutting blades difficult cutting granite, remove the blade speed limit is appropriate. Granite tiles in the production, the use of smaller diameter diamond saw blade, the line speed can reach 35m / s.(2) Cutting Depth: diamond cutting depth is related to wear, effective cutting, saw cutting force conditions and the nature of the important parameters of stone. Generally speaking, when the circular blades line speed diamond saw blade is high, should be selected for cutting of small depth, from the current technology, the cutting depth of the diamond can choose between 1mm ~ 10mm. Usually with a large diameter saw blade cutting granite blocks, the cutting depth can be controlled within 1mm ~ 2mm between the feed rate should be reduced at the same time. When the line speed diamond saw blade is large, a large cutting depth should be selected. But in performance and tool strength saw the extent permitted, should try to take a greater depth of cut for cutting to improve cutting efficiency. When the machined surface when requested, should be used small depth of cut.(3) Feed speed: Cutting feedrate incurs stone feed rate. Its size sawing rate impact, the force and the cutting blade heat dissipation area. Its value should be based on the nature of the selected cutting stone.

When coarse diamond size and granularity of a single
sharp saw blade, cutting efficiency is high, but the flexural strength of agglomerated diamond drop; when fine or coarse grained diamond size when mixed with saw blade durability, but efficiency is low. Considering these factors, choose diamond size 50/60 mesh is more appropriate.
(2) the selection of diamond concentration distribution
Within a certain range, when the diamond concentration changes from low to high, the blade sharpness and cutting efficiency 4 inch saw blades decreased, while life is gradually extended; but the concentration is too high, the blade becomes blunt. The use of low concentration, coarse, efficiency will be increased. The use of various parts of the cutting head when the different roles of different concentrations (i.e. three or more layer structure in the intermediate layer can be used in low concentrations), the saw blade during the work head to form an intermediate groove, with helps prevent blade deflection, thereby improving the quality of stone processing.
3 diamond strength selection
Is to ensure the strength of the diamond cutting important indicator of performance. High intensity causes the crystal is broken, the polishing abrasive grains are in use, the sharpness decreased, resulting in performance degradation tool; diamond enough strength when subjected to shock easily broken, difficult to bear heavy cutting. It should choose a strength of 130 ~ 140N.
4 choice of binder phase
Depends not only on the performance of concrete saw blades 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 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.
5 Select the sintering process
As the temperature increases, the core bits for concrete carcass densification improved flexural strength also will increase, and with the holding time, the blank matrix and diamond caked flexural strength increased firstly and then decreased, you can choose 120s at 800 ℃ sintering processes to meet performance requirements.

diamond saw blade matrix detection indicators
testing methods
Diamond saw blade matrix is normally provided by 65Mn, T12 material composition with slotted disc, after quenching and wet diamond polishing pads tempering heat treatment is made. The processing required dimensional accuracy and geometrical precision both requirements. Dimensional accuracy requirements include: diameter, diameter, thickness, nozzle, gear units. Shape and position accuracy including: roundness, concentricity, flatness, parallelism, runout, face runout.
Diamond saw blade sawing work must ensure that small deformation, rigidity in order to make uniform thickness sawn slate of board rate. To meet these requirements, you must make multiple blade leveling and stress adjustment. Side jump flatness and smaller, more uniform stress. The better usage of the blade. Currently the world's most advanced set of stress testing and handling equipment based sports school saw peace as one detected by stress testing and rolling unit, flatness and side jump correction unit, automatic detection unit and PC software control unit four most components. How it works: the first high-precision laser sensor measures the base of the indicators, and then through the PC software control unit determines whether the 14 inch saw blade indicators meet the requirements in order to decide whether or not to stress rolling unit, flatness and side jump correction unit issued a directive , the substrate to be corrected. Can achieve the tension side jump, jump diameter, flatness four indicators integrated automatic processing.
The flatness and side jump test, which flange plane to plane, by laser sensor slide rail precise detection surface of the substrate while rotating the highest point and the lowest point of the distance between the same plane. Some devices also currently 50mm2 area to the highest point and the lowest point of the research object, the substrate surface of flap wheels the "package" particularly sensitive, and the image is displayed on the screen. If the base body pass, the point of the substrate surface are uniformly distributed to the reference plane in the center of a small control zone.
To the base of stress testing, is the use of a substrate pre a constant deformation, and by the laser sensor 90 axially proximal the deformation amount of the matrix stress detection to quantify the same time, avoiding the thickness and other factors of the stress detection effects.

Diamond Certification
In fact, to identify the authenticity of a diamond, with a 10x magnifying glass only as an auxiliary operand can be a simple observation
Method One:
Observed diamond waist, waist-shaped frosted if it is best suited for this method, because more than any diamond imitations hard abrasive tools to take, it will not appear as risk imitations like thin strip lines, diamond waist is grainy appearance.
Method two:
Also because of the diamond imitations than to take a hard, run imitations facet ridge often feel obtuse than diamond, and diamond facets must be a sharp ridge. Method three:
Than the risk-based diamond imitations hard, take imitations facet ridge often appears wear. Method four:
If left natural diamond surface, there is the opportunity to discover the natural surface of the diamond's unique "triangular growth pattern five:
If the diamond appear Bengduan mouth, usually are ladder-like appearance, but it will take very different presentation of imitation goods curved arc or conchoidal. A specific gravity test:
There are a measure of the proportion of drill bits liquid gemstone weight; specific gravity of 3.32 we can use the test liquid used genuine diamonds. The specific gravity of 3.52 natural diamonds, the proportion of all natural diamonds placed in the water will sink, so that both the proportion of water floating in gems, diamonds can be sure it's not.
(2) penetration observation:
Diamond has a high refractive index, the higher the refractive index of the diamond, the stronger the light reflected power, relatively low degree of perspective. May prepare a picture of a straight paper to be measured two unknown diamonds, face down, capping in a straight line from the back of the diamond to the naked eye directly read on, if they floor polisher pads can see the diamond under pressure a straight line, it is certainly not a natural diamond.
3 lipophilic law:
There is a diamond on the oil "oil absorption" fake diamond does not have this feature. Diamonds dipped slightly in the face amount of grease, rub the diamond with the thumb, the thumb will feel a plastic viscosity, easy to slide, and then let the thumb with fake diamonds slippery feeling.
4 breathe test:
Natural diamond heat transfer capacity, good heat disperse quickly. Diamond to be tested near your mouth, breathe gently, so that the tested diamond covered with mist, then immediately watch the diamond mist volatile situations, such as natural diamonds, the fog will be immediately dispersed, whereas in the fog fake diamonds remain for a while, until dispersed.

CVD diamond thick welding tool
CVD diamond thick film soldering tool is to first cut a good CVD diamond films once welded to the base (usually a class K carbide) to form a composite sheet, and then polishing composite sheet, the diamond blade second welded to the tool body, sharpening into the required shape and edge.Manufacturing process: high-quality CVD diamond films prepared by laser cutting → → welded into one composite piece → polishing → secondary composite sheet welded to the tool body → Grinding → test. Here are a few key processes, such as cutting, welding, polishing and grinding, etc.A laser cuttingCVD diamond film hardness, non-conductive (conductive CVD diamond now, but itsresistivity great), strong wear resistance, conventional machining and wire cutting method is not suitable for CVD Diamond Thick cut. Efficient processing method is laser cutting.(2) a weldingA welding means under vacuum CVD diamond thick film substrate is welded to some form a composite sheet. Diamond between the metal and the general poor weldability. Currently, diamond thick welding tool used mainly surface metallization methods. Solder the silver-copper alloy containing titanium, titanium role in the welding process of heating the surface of the diamond film and the reaction to produce an intermediate layer of TiC, the diamond film surface metal, thereby improving the welding strength.Welding Class K matrix is usually carbide. In the high vacuum conditions, using diffusion brazing welding process added, Ag-Cu-Ti alloy as an intermediate layer, the diamond films on cemented carbide substrate weld, weld strength to meet the machining requirements.3 Composite PolishingThe purpose is to polish the upper surface of the blade (i.e., the rake face) polished to a mirror, generally required to achieve Ra0.1μm less. After polishing tool rake face and the chip can reduce friction and adhesion, extend tool life; also can improve the flatness and sharp blade, improve machining accuracy. Polishing a composite sheet with a special polishing machine.4 secondary weldingSecond welding refers to the composite sheet welded to the tool body. Equipment used mostly for concrete blade high frequency induction welding equipment, the use of silver-copper solder and solder flux. Soldering temperature is between 650 ~ 700 ℃. Temperature is not too high, the welding process the welding surface should be kept clean. Rational use of flux help to improve weld strength and improving the composite sheet material substrate and knife welding performance. Generally the strength of the second weld 180 ~ 200MPa, the diamond cutting tool to meet the processing requirementsIn addition, in order to improve the appearance of the tool can be worn away excess oil stone of silver and copper, with the blasting method to remove the surface oxide layer with Ni plated with passivation liquid immersion method or tool body to prevent the oxidation of rust.CVD diamond grinding with high hardness and wear resistance, grinding extremely difficult. Now masonry blades widely used methods similar to PCD tool sharpening.5 Equipment: using a special tool grinder, equipment manufacturers in the United Kingdom COBORN Corporation, Taiwan KARMAM, Switzerland EWAG Corporation and Beijing Dean companies. Its main features include: straight edge grinding and circular grinding, circular grinding, and also includes a cylindrical conical flank flank formation and tapered cylindrical flank with a combination. In order to achieve these functions, requiring major sports machine include: machine tool spindle (wheel) rotational motion; spindle reciprocating linear motion; turret rotary motion, with the precise alignment of the microscope or projector rotation center, get a different tip round arc radius.
