Cutting parameters of diamond blades
- Nov 03, 2017 -
As a diamond blade suppliers,now we're pleasure to tell all the customers or friends about some cutting parameters of diamond blades.
(1) blade line speed: In actual work, the linear speed of the diamond saw blade is limited by the conditions of the equipment, the quality of the saw blade and the nature of the saw blade. From the best saw blade life and sawing efficiency, the speed of the saw blade should be selected according to the nature of the different stone. Sawing granite, the saw line speed can be selected in the range of 25m ~ 35m / s. For the quartz content is high and difficult to cut the granite, saw blade line speed limit is appropriate. In the production of granite brick, the use of diamond saw blade diameter is smaller, line speed can reach 35m / s.
(2) blades cutting depth: blades cutting depth is involved in diamond wear, effective sawing, saw blade force and saw the nature of the important parameters of stone. In general, when the diamond saw blade line speed is high, should choose a small cut depth, from the current technology, the depth of the sawing diamond can be selected between 1mm ~ 10mm. Usually with large diameter blade saw the granite block, the sawing depth can be controlled between 1mm ~ 2mm, at the same time should reduce the feed speed. When the linear speed of the diamond saw blade is large, a large cutting depth should be selected. However, when the sawing performance and tool strength within the scope of permission, should try to take a larger cutting concentration for cutting to improve the cutting efficiency. When required for machined surfaces, small depth cutting should be used.
(3) Feeding speed: Feeding speed is the feed rate of cutting stones. Its size affects the sawing rate, saw blade force, and the heat dissipation of the sawing area. Its value should be selected according to the nature of the sawed stone. In general, sawing soft stone, such as marble, may be appropriate to improve the feed speed, if the feed speed is too low, more conducive to improve the cutting rate. Sawing fine grain structure, relatively homogeneous granite, may be appropriate to improve the feed speed, if the feed speed is too low, the diamond blade is easy to be polished. However, cutting the coarse grain structure and soft and hard granite, should reduce the feed speed, otherwise it will cause the blade vibration led to diamond fragmentation and reduce the cutting rate. Sawing granite feed rate is generally selected in the range of 9m ~ 12m / min.
