(1) saw the line speed: in actual work, the line speed of diamond saw blade by blade quality and equipment condition, is only the limiting nature of cutting stone. From the best saw blade life and sawing efficiency, the line speed of the saw blade should be selected according to the properties of different stones. When sawing granite, the speed of the saw line can be selected within the range of 25m to 35m/s. For granite with high content of quartz and difficult to sawing, the lower limit of the speed of the saw line is appropriate. When the granite tile is produced, the diamond circular saw blade is small in diameter and the line speed can reach 35m/s.
(2) sawing depth: the sawing depth is an important parameter that involves diamond wear, effective sawing, saw blade force and sawing stone properties. Generally speaking, when the wire speed of diamond circular saws is high, small cutting depth should be selected. From the current technology, the depth of sawing diamond can be selected from 1mm to 10mm. Usually cut granite blocks with large diameter saw, sawing depth can be controlled at 1mm ~ 2mm, feed rate should be reduced at the same time. When the line speed of the diamond circular saw blade is large, a large cutting depth should be selected. But when the performance of the sawmill and the strength of the cutting tool is permitted, the larger cutting concentration should be taken as far as possible to improve the cutting efficiency. Small depth cutting should be used when the processing surface is required.
(3) feed speed: the feed speed of the stone is cut through the speed of cutting the knife. Its size affects the sawing rate, the force of the saw blade and the heat dissipation in the sawing zone. Its value should be selected according to the properties of the sawn stone. Generally speaking, cutting the soft stone, such as marble, can appropriately increase the speed of the knife, if the speed of the feed is too low, it is more beneficial to improve the cutting rate. The granite with fine grain structure and relatively homogeneous can improve the speed of the feed, and if the speed of the feed is too low, the diamond blade is easy to be smoothed. But when cutting coarse grain and hard and uneven granite, the cutting speed should be reduced, or the saw blade vibration will cause the diamond fragmentation to reduce the sawing rate. The cutting speed of sawing granite is generally selected within the range of 9m to 12m/min.
