wood saw blades production methods and their application of the

 Diamond saw blade production methods and their application of the effect of different production methods and application performance saw blade, the method currently used mainly to suppress the production of sintered diamond saw, a few blades produced using electroplating, sintering  GUSHI colde saw blade method common with cold pressed sintered , hot pressing and sintering welding three main ways. Saw another frequency welding welding and laser welding points.
  Diamond saw blade in a wide range of applications in developed countries, more mature technologies and standards, product and market segments have been, but with the further development of the technology of diamond saw blades, diamond saw applications will continue to expand, the market will continue to grow. Diamond saw domestic market has become the world's largest market, but aspects of the blade level, variety, range of applications and manufacturing technology there are still a wide gap with developed countries, regardless of technology or the market has much room for development, I hope GUSHI cutting disc for drill  the industry ambitious people to continue their efforts to eliminate the gap as soon as possible. In general, diamond saw blade contrast harsh working environment, the primary use of the product is sawing stone, widely used in large marble, granite, ceramic tiles and concrete finished cutting, the stone, the building materials industry and the primary widely used in the processing equipment.
 Cutting circular saw blades have manipulated lunch, effectiveness, good processing quality and other advantages. But noise than the large, rigid blade poor. Process prone cutting blade runout, deviation, resulting parallelism of the workpiece to be cut is poor. Saw Spindle GUSHI abrasive flap wheels  unbearable than the large sawing force, swinging the cutting process occurs without grams less than the cut-out line, although the added thickness of the blade can improve its rigidity, it is still difficult to guarantee parallel slices. In addition, adding the thickness of the blade not only adds costs and makes adding kerf width decreases the volume ratio.

affect wood saw blades cutting parameters

Sawing sawing parameters of the main parameters of diamond saw blades : peripheral speed , feed rate , the transfer speed. Circumferential velocity : in practical work , diamond saw blade line speed is equipment conditions, limitations, and the quality of the blade sawing stone nature. From the best blade life and cutting efficiency , the linear GUSHI turbo diamond blade  velocity of the blade should be selected according to the different nature of the stone . When cutting granite , the blade can be selected by the line speed in the 25 ^} 35m / s range. For high quartz content and difficult cutting granite , remove the saw blade line speed limit is appropriate. In the production of granite tiles, using a diamond saw blade smaller diameter , the line speed can reach 35 ^} 50m / s. The amount of feed : feed quantity is involved diamond wear , effective sawing , saw the forces and vital parameters were sawing stone  GUSHI metal grinding wheel by nature . Generally speaking , when a higher line speed diamond saw blades , you should select a small depth of cut.
Feed rate: Feed rate Jibei stone cutting feed rate . Its size affect the rate of cutting , the blade and the cutting force by the heat dissipation area . Its value should be based on the nature of the stone sawing selected . In general, the sawing softer stone, such as marble, may be  GUSHI cutting discs appropriate to increase the feed rate, if the feed rate is too low , more conducive to improving cutting rates. Sawing fine structure , relatively homogeneous granite , may be appropriate to increase the feed rate, if the feed rate is too low , diamond blade easily be polished .

Some reasons concrete diamond blades wear

(1) diamond size: diamond particle size used in the range of 30/35 to 60/80. The more hard rock, should be selected with a finer granularity. Because under the same pressure conditions, the more detailed the GUSHI turbo diamond blade  more diamond sharp cut in favor of hard rock. Further, the general requirements of a large-diameter blade cutting efficiency high, the particle size should be selected with a coarser, such as 30/40, 40/50; lower small-diameter blade cutting efficiency requires a smooth cross-section of rock cutting, should to a smaller particle size, such as 50/60, 60/80.
(2) Segment concentration: the so-called diamond concentration, refers to the density distribution in the working layer of diamond carcass (ie, the weight of the diamond contained within the unit area). "Norms" provides the carcass per cubic centimeter work containing 4.4 kt diamond, its GUSHI carbide saw blades  concentration was 100%, with 3.3 karats of diamonds, its concentration was 75%. Represents the volume concentration of the volume occupied by the number of diamond agglomerates, and that, where a concentration of 1/4 volume of the total volume of diamond is 100%. Increasing the concentration of diamond is expected to prolong the life of the blade, i.e., reduced because of the increased average concentration of each piece of diamond cutting forces suffered. However, increasing the depth of the blade will increase the cost, so there is a concentration of the most economical and the concentration increases with the shear rate increases VS. (3) the hardness of head binders: In general, the higher the hardness of the binder, the stronger its wear resistance. Thus, when a large rock cutting abrasive, hardness should be high binding agent; when cutting soft rock material, the hardness of the binding agent should be low; when sawing hard and abrasive rock large, the hardness of the binding agent should be moderate . (4) force effects, temperature effects and grinding damage: cutting stone diamond saw blades in the process will be subject to centrifugal force, cutting power, cutting hot alternating load effect.
As the force and temperature effects caused by diamond saw blade worn donate damage.
Force effect: the cutting process, the saw blade to be  GUSHI carbide drill bits subjected to an axial force and tangential force. Because of the force acting radially and in the circumferential direction, so that the wavy blade axially, radially dish-shaped. Both can cause deformation of the rock section is not straight, stone waste more time sawing noise, vibration intensified, resulting in diamond caking early damage, reducing blade life. Temperature effect: the traditional theory: the effect of temperature on the blade process mainly manifested in two aspects: First, cause agglomeration of diamond graphite; Second, causing thermal Ili diamond and diamond particles resulting from the carcass of premature loss . New research indicates that: the heat generated during the cutting process the incoming primary agglomeration. Arc temperature is not high, generally between 40 ~ 120 ℃. The abrasive grinding points, but a higher temperature, generally between 250 ~ 700 ℃. The average temperature of the coolant only reduce the arc zone, the temperature of the grains was less affected. Such temperature does not result in charring of graphite, but will occur between the abrasive friction properties and the workpiece changes, and to thermal stress between diamond and additives, which led to a fundamental failure mechanisms diamond bend of. Research shows that the temperature effect is to make the maximum impact factors blade breakage.
