Sawing parameters of diamond saw blades

Saw blade speed:

In practice, the linear speed of diamond circular saw blade is limited by the equipment conditions, the quality of the saw blade and the nature of the stone being cut. In terms of the optimal service life and sawing efficiency, the linear speed of saw blade should be selected according to the properties of different stones. When cutting granite, saw blade linear speed can be selected in the range of 25m ~ 35m/s. For granite which has high quartz content and is difficult to cut, it is advisable to lower the linear speed of saw blade. In the production of granite brick, the diamond circular saw blade diameter is small, linear speed can reach 35m/s.

Cutting depth

The sawing depth is an important parameter related to diamond wear, effective sawing, force condition of saw blade and properties of stone being sawed. Generally speaking, when the linear speed of diamond circular saw blade is high, small cutting depth should be selected. Technically speaking, the depth of diamond sawing can be selected between 1mm and 10mm. Usually with a large diameter saw blade saw cutting granite waste materials, sawing depth can be controlled between 1mm ~ 2mm, at the same time should reduce the feed speed. When the linear speed of diamond circular saw blade is large, the cutting depth should be large. However, when the performance of the saw and the strength of the cutting tool are allowed, the cutting concentration should be as large as possible to improve the cutting efficiency. When the machined surface is required, small depth cutting should be used.

Feed speed

Feed speed is sawed stone feed speed. Its size affects the sawing rate, the force of the saw blade and the heat dissipation of the sawing area. Its value should be selected according to the nature of the sawn stone. Generally speaking, saw cutting soft stone, such as marble, can appropriately improve the feed speed, if the feed speed is too low, more conducive to improving the saw rate. Saw cutting fine grain structure, relatively homogeneous granite, can appropriately improve the feed speed, if the feed speed is too low, the diamond blade is easy to be ground flat. But when sawing coarse grain structure and uneven hardness of granite, should reduce the cutting speed, otherwise it will cause the vibration of the saw blade to lead to diamond fragmentation and reduce the sawing rate. The cutting speed of granite is generally selected in the range of 9m ~ 12m/min.
