Impact Diamond Round Saw Chip efficiency and lifetime factors and the Diamond Cutting

Wire process parameters particle size, concentration, binder hardness. It has cut the number of blades can be wire-speed, concentration and feed rate of cutting.

One, cutting parameters (1) Blade speed: In practice, the line speed diamond saw blade by equipment conditions, stone cutting saw blade quality and are only limited in nature. From the best blade life and cutting efficiency, the stone should be based on the nature of the choice of different blade of the line speed. Cutting granite, the blade speed can be 25m ~ 35m / s range selected. The high quartz content of granite sawing difficult, remove the blade speed limit is appropriate. Granite tile in the production, the use of smaller diameter diamond saw blades, wire speed can reach 35m / s.

(2) Cutting depth: Cutting depth is related to diamond cutting wire manufacturer wear, effectively cutting, saw the situation by force and by the nature of the important parameters for cutting stone. In general, when the diamond saw blade speed is high, consumers should select a small depth of cut from the current technology, the cutting depth of the diamond can choose between 1mm ~ 10mm. Usually large diameter blade sawing granite blocks, the cutting depth can be controlled in 1mm ~ 2mm between the feed rate should be lowered at the same time. When the diamond saw blade speed is high, a large depth of cut should be selected. But when the saw the performance and Tools Strength to the extent permitted, should try to take a larger concentration of cutting cutting to improve cutting efficiency. When the surface of processing the request should be using a small depth of cut.

(3) feed rate: feed speed Jibei stone cutting feed rate. It is the size of the impact of cutting rates, blade cutting area by force and heat dissipation. Its value should be the nature of cutting stone selected. In general, cutting soft stone, such as marble, can increase proper feed rate, if the feed rate is too low and help to improve cutting rate. Cutting fine structure, more homogeneous granite, can increase proper feed rate, if the feed rate is too low, diamond cutting wire manufacturer blade easily be flattened. However, coarse-grained structure of soft and hard uneven cutting granite, should reduce the feed rate, otherwise it will lead to blade vibration lead to fragmentation and reduce the cutting rate of diamond. Granite cutting feed rate is generally selected within 9m ~ 12m/min.

Second, other factors (1) Diamond Size: common size of diamond in the range of 30/35 ~ 60/80. The more hard rock, with a smaller particle size should choose. Because the same pressure conditions, the smaller the diamond the more sharp will help cut into the hard rock. In addition, the general requirements of large diameter of the saw blade cutting efficiency is high, should select the use of coarse granularity, such as 30/40, 40/50; small diameter of the saw blade cutting efficiency is low, required cross-section of rock cutting and smooth should choose smaller size, such as 50/60, 60/80.

(2) head concentration: the so-called diamond concentration, diamond refers to the distribution in the working layer of the density matrix (the unit area contained in the diamond weight). "Standards" provides that the work of matrix per cubic centimeter containing 4.4 karats of diamonds, its concentration is 100%, with 3.3 karats of diamonds, its concentration is 75%. Agglomeration of diamond volume concentration that the number of share volume, and that when the volume of the total volume of diamond 1 / 4 concentration of 100%. Expected to increase the concentration of diamond saw blade to extend the life of, because increasing the concentration that reduces the average received by each piece of Diamond Cutting Wire force. But the increase in depth will increase the cost of the saw blade, so there is a concentration of the most economical, and Cheng cut the rate of concentration with the increase.

(3) head binder hardness: In general, the higher bond hardness, its wear resistance is stronger. Thus, when cutting abrasive rock big time, should the high bond hardness; when cutting soft rock material, the binding agent should lower hardness; when the cutting and polishing of the great hard rock, the binding agent should moderate hardness .

(4) strength effect, temperature effect and grinding damage: diamond cutting wire manufacturer saw blades in the process of cutting stone, will be subject to centrifugal force, cutting force, cutting heat, etc. The role of alternating load.
