Saw blade plate quality is very important. Because the blade to adjust the rotation, it has to pass the cutting force while keeping the stability of the work . Not only has excellent static blade geometry GUSHI carbide saw blades and accuracy , and more importantly, its dynamic characteristics. When the cutting blade continuously , the heat generated sawtooth cutting saws will be transmitted to the temperature rise of saws , saws quality in this case also to maintain the accuracy of position , and the poor quality of the blade saw board warpage occurs , the impact of cutting accuracy. Dynamic stability is particularly important for sawing boards of several pieces into a fine blade set GUSHI colde saw blade conditions for use . When multiple devices using a set piece saw blade instability , how can guarantee the quality of the longitudinal opening material . Saw blade plate and the head is an integral part of quality . Depending on the angle of the blade to grind the teeth , with left , center and right . There are left, right , middle . Tooth tooth width ( tooth density ) with the cut material size , wall thickness of the blade a great relationship, the more books tooth wall thickness is relatively dense , thick wall thickness should open GUSHI stone polishing pads wide more, do not understand what you can always ask me, usually online.
To be determined according to the thickness of the blade cutting the material , size open tooth , first , on the edge of the blade off the mouth of the well , and the second , on the grinding wheel grinding is good , and the third , chamfer should be uniform.

Research stone diamond bit drilling parameters affect its surface temperature
Drilling in stone, because of relatively high speed movement between the diamond drill and stone complex tribological phenomena arising in the contact interface. Friction between diamond drill and stone, as the stone poor thermal conductivity, most of the heat transferred diamond segment, making diamond drill surface temperature, resulting in diamond graphite, diamond cutting capacity reduced, which leads to the bit matrix thermal polishing pads for granite fatigue, lower strength and stiffness, increased noise when processing stone, increased vibration, reduce bit life, serious diamond head off, causing injury to the operator, but also affect the processing quality and efficiency. Research diamond bit drilling parameters affecting its surface temperature to identify factors that influence the relationship between surface temperature and the law, determine a reasonable processing parameters, help to improve the diamond drill bit life and reduce processing costs, improve processing quality.
Experimental conditions are diamond segments using a Cu powder, a diamond particle size of 60 to 80 mesh, using pressing sintering method, the welding head in the high speed steel cylinder. Diamond drill diameter φ37mm, high-5.6mm, width 2mm, base diameter φ35.6mm, height 45mm. Processing equipment used XK5032C type CNC milling machine, the device implements the X axis, automatic feed three directions Y and Z axes, spindle cooling method using water-cooled. The temperature measured with an infrared wood band saw blades temperature measuring surface of the tool, the measurement temperature range of -50 ~ 650 ℃. Direct l2 ℃ measured at room temperature conditions. Stone were selected marble, sandstone and granite. This experiment studies the spindle speed, feed rate and stone impact performance parameters such as surface temperature of the diamond drill bit. Experiment was carried out under dry cutting conditions, machining state. Results of impact 3.1 feed rate on temperature
When processing stone diamond drill, impact drill surface temperature of many parameters, including diamond properties, performance bond, stone physical and mechanical properties, processing parameters, cooling parameters. Effect on the surface temperature of the diamond drill bit experimental study of stone processing parameters and performance. Figure 2 is the spindle speed is 300r/min, the feed rate was 10mm/min, 15mm/min, 20mm/min, 25mm/min, when the surface temperature of the pre-drill drilling marble drilling time curve. As can be seen in Figure 2, in the four kinds of conditions of feed rate, the surface temperature of the diamond drill bits are increased with the increase of the processing time. In the early stage of diamond tools manufacturer processing, the temperature increases relatively slowly, when the processing time exceeds 4s, sharp increase in temperature. When the processing time reaches 10s, the diamond drill is the initial surface temperature 5 times. Figure 3 feed rate versus temperature curve for the processing of marble. From the figure can be seen in the feed rate l0 ~ 20mm/min the temperature rises slowly, the feed rate of 20 ~ 30mm/min, the temperature rise is most obvious, the most heat in this interval drills stone processing generated. As the drilling process, the diamond drill bit with a large stone surface friction, resulting in diamond drill surface temperature rise. Due to the low thermal conductivity of marble, and a high thermal conductivity of the tool, a large part of the heat conducted to the diamond drill bit, diamond drill causes the surface temperature. Since the feed rate increases, the cutting face of the contact per unit time increases, the number of cutter contact with the stone, the surface temperature increases.

Affect the efficiency of diamond saw blade main reason
One , sawing 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 difficult cutting granite , remove the blade speed limit is appropriate. Granite tiles in the sds hammer drill bits 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 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 stone polishing pads 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 . Generally speaking , sawing softer stone, such as marble, may industrial saw blades be appropriate to increase the feed speed , if the feed rate is too low, more conducive to high cutting rates . Sawing fine structure , relatively homogeneous granite, may be appropriate to increase the feed speed , feed rate is too low if the diamond blade easily be polished . But sawing UNEVEN coarse granite structure , should reduce feed speed , otherwise it will cause the blade vibration and reduce fragmentation leading diamond cutting rates . Granite cutting feed rate is generally 9m ~ 12m/min within the selected range .

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 difficult cutting granite , remove the blade speed limit is appropriate. Granite tiles in the sds hammer drill bits 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 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 stone polishing pads 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 . Generally speaking , sawing softer stone, such as marble, may industrial saw blades be appropriate to increase the feed speed , if the feed rate is too low, more conducive to high cutting rates . Sawing fine structure , relatively homogeneous granite, may be appropriate to increase the feed speed , feed rate is too low if the diamond blade easily be polished . But sawing UNEVEN coarse granite structure , should reduce feed speed , otherwise it will cause the blade vibration and reduce fragmentation leading diamond cutting rates . Granite cutting feed rate is generally 9m ~ 12m/min within the selected range .

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.

blade grinding develop some of the trends
An alloy saw blade when grinding a number of factors can not be ignored, the matrix deformation, inconsistent thickness, bore tolerances big. Congenital defects of the base there is a problem, no matter the kind of graphics device, there is grinding errors. Matrix deformation on the two side angle bias; matrix inconsistent thickness right sand paper rear corner and edge front corner of bias, such as the existence of cumulative tolerance is too large, the quality and accuracy of the blade severely affected. 2, grinding teeth grinding effect on the structure. Alloy saw blade grinding machine structure and assembly is good or bad, about two types of models currently on the market: one is floating in Germany Seoul ink types. The type with vertical grinding off, all the advantages of hydraulic stepless movement, all of the feed system using V-shaped guide rail and ball screw work, grinding or big arm with slow feed forward, rewind retraction, Clips cylinder regulator center support piece flexible and reliable, accurate positioning pulling teeth, blade positioning center firmly self-centering, arbitrary angle adjustment, cooling flush reasonable, man-machine interface, high precision grinding off, pure grinder rational design; Type II, which is currently Horizontal such as Taiwan and Japan models, the presence of mechanical transmission gears and mechanical clearance dovetail slide accuracy, stable performance low clip, branched piece center adjustment difficult, pulling teeth institution or poor reliability, flat two sides, left and right rear corner is not a central mill cut, resulting in large deviation angle difficult to control, mechanical wear disaster ensure accuracy. 3, welding factor. Welding Alloys for moderate deviations and impact grinding precision, resulting in a large pressure while grinding, while pressure is small, the posterior horn of the same generation of the above factors, welding angle difference, human factors will inevitably have on the grinding wheel, etc. factors produce unavoidable impact. 4, wheel width affect the grinding stone quality and size. Optional wheel running gold films, note wheel size, granularity is too coarse grinding wheel produced traces wheel easy to plug the optional fine granularity grinding less easy to burn knife. Grinding wheel diameter and length width thickness is based alloy and alloy tooth width or different each face the situation, not a corner after corner or front wheel specifications are the same as any different from tooth grinding, must be targeted to choose a suitable Specifications Wheel. 5, grinding feed speed. Alloy saw blade grinding entirely good or bad decision grinding feed rate, generally alloy saw blade feed rate at from 0.5 to 6 mm / s can not exceed this value should be 20 per minute teeth, the ultra in every minute 20 tooth feed rate is too large, it will have serious knife tumors or burning alloy wheel impact generated convex and concave surface precision grinding wheel wasted. 6, grinding feed rate, the choice of wheel size on the amount of feed has an extremely important significance. General grinding wheel recommendation to use 180 # 240 # 240 # to use at most an opt 280 # 280 # to 320 #, or to adjust the feed rate. 7, grinding center. All grinding the blade and the substrate as the center, rather than with the blade as the center, get it out flat grinding center, rear angle, rake angle with a processing center can not be sharpened a saw blade, saw blade grinding three processes the center can not be ignored. Side angle grinding alloy thickness is still careful observation, the thickness change with different grinding center, regardless of how the alloy thickness, the grinding surface grinding wheel center line and the welding position to be maintained in a straight line, or have a poor impact angle cutting. 8, pulling teeth institutions can not be ignored. Regardless of how the structure of any grinding, pulling teeth designed to coordinate accuracy sharpening design quality, machine adjustment pulling teeth acupressure reasonable position in the tooth surface, and not with the move is extremely critical, back teeth when pulling teeth claw should flexible and reliable. 9, Clips institutions: institutions firmly clip stable and reliable quality is the main part of the Brothers, the Brothers when any clip institutions can not have the slightest loosening, or grinding teeth deviation seriously out of control. 10, grinding itinerary. Regardless of wet tile saw any part of the blade grinding, grinding grinding stroke is very important, generally require grinding wheel or exit out of the workpiece 1 mm 1 mm is appropriate, or tooth blade produces two faces. 11, the program options: Sharpening generally provided with a rough and fine grinding three different programs options, depending on the degree of demand for product selection, and finally recommended when grinding rake angle grinding process. 12, coolant grinding teeth grinding fluid that is good or bad decision. Partridge produce large amounts of tungsten grinding, diamond grinding wheel powder, not timely flushing and cleaning of grinding wheel tool surface pores, causing the surface of the grinding tool can not grind finish, there is not enough cooling will burn alloys.

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.

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.
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.

What are the current market and diamond tools
At present, China's use of abrasive machining, geology drill and stone cutting
tools manufacturing technology level has been greatly improved, the product has
formed, standardization, variety specification is complete, stable product
quality, some products in the hss drill bits international market certain competitiveness. All
kinds of diamond tools also been widely used in various industries, and
achieved significant economic benefits, but on the whole diamond tools
industry, still need to improve the industrial planning, broaden application
areas, creating an international brand.
1 Industry Planning: strengthen macro-control management
Because the blind development, hardware and tools, especially diamond tools
production layout appears scattered and chaotic situation everywhere, generally
small-scale producers, production is not centralized, process technology, the
lack of market competitiveness, product quality tools sales market instability,
competition disorder, price confusion, economic efficiency is not high.
(2) Product Development: Widening the application areas of diamond
The current domestic production tools as well as new product development,
technology research and other aspects of insufficient capital investment, to
increase tool industry investment, pay close attention to new product
development and new technologies, promotion of new technology and continue to
broaden the field of application of diamond to enhance diamond tools industry
overall technological level and market competitiveness, variety, quality of
survival, to scientific and technological progress and development.
Tools to meet the needs of the market at home and abroad, we must accelerate
the development of new products, improve product quality, increase product
variety and improve production. In recent years, machinery, gems, medical
equipment, wood, glass, steel, stone handicrafts, ceramics and composites
processing of non-metallic brittle materials the metal grinding wheel field of diamond tools demand
increases every year, at present, these products are domestic or imported, must
as soon as possible developed a variety of high-quality range of tools to
replace imports.
Currently urgent need to develop products: oil drilling PDC bits, stone
polishing with diamond grinding blocks, core bits, diamond honing stone,
diamond film coating tools, diamond wheel, rubber plastic-bonded diamond tools,
PCD diamond tools, diamond needle, nozzle, diamond heat sink and transistors
and other products. To ensure the quality of their products, we must accelerate
new technologies, promotion of new technology, such as vacuum welding
technology, spark sintering technology, uniform technology of diamond, diamond
-plated iridium technology and metal bonding technology, laser welding
technology.
3 development of the industry: joint build international brands
Enterprise, innovation is advanced technology, and constantly improve the
production process, reduce production costs and improve economic efficiency.
Take the group or joint venture on the turbo diamond blade road, the formation of several large
enterprise groups, to guide development of the industry, to create their own
brand, and actively participate in international competition. Relying on
technological progress, increase scientific and technological input, update
equipment, pay close attention to new technologies, new processes, new product
research and promotion, to improve tool substrate material usage, accelerate
the development of China's hardware tools industry to further enhance economic
efficiency and overall level of technology.
