Cutting parameters of diamond saw blade
Parameters of saw blade linear speed, cutting depth and feed speed.
(1) saw blade linear speed: in actual work, the linear speed of diamond circular saw blade is limited by the equipment conditions, saw blade quality and the nature of the stone to be cut. In terms of the best service life and cutting efficiency of the saw blade, the linear speed of the saw blade should be selected according to the nature of different stones. When sawing granite, the linear speed of saw blade can be selected in the range of 25m-35m / s. For granite with high quartz content and difficult to cut, the lower limit of the linear speed of saw blade is appropriate. In the production of granite tiles, the diameter of diamond circular saw blade is small, and the linear speed can reach 35m / s.

(2) sawing depth: the sawing depth is an important parameter related to diamond wear, effective sawing, stress on the saw blade and the nature of the stone to be sawed. Generally speaking, when the linear speed of diamond circular saw blade is high, a small cutting depth should be selected. From the current technology, the depth of diamond cutting can be selected between 1mm-10 mm. Generally, when a large-diameter saw blade is used to cut granite, the cutting depth can be controlled between 1mm-2mm, and at the same time, the cutting speed should be reduced. When the linear velocity of diamond circular saw blade is large, a large cutting depth should be selected. However, when the performance of the saw and the strength of the cutting tool are within the allowable range, the cutting concentration should be as large as possible to improve the cutting efficiency. When the machining surface is required, small depth cutting shall be adopted.

(3) feed speed: the feed speed is the feed speed of the stone being sawed. Its size affects the sawing rate, the force on the saw blade and the heat dissipation in the sawing area. Its value should be selected according to the nature of the stone to be sawed. Generally speaking, the cutting speed of soft stone, such as marble, can be increased properly. If the cutting speed is too low, it is more conducive to improve the cutting rate. If the cutting speed is too low, the diamond edge is easy to be polished. However, when sawing the granite with coarse grain structure and uneven hardness, the cutting speed should be reduced, otherwise the vibration of the saw blade will lead to diamond fragmentation and reduce the cutting rate. The cutting speed of sawing granite is generally selected in the range of 9m-12m / min
