Factors affecting the efficiency and life of diamond saw blades include sawing process parameters and diamond grade, particle size, concentration, bond hardness, etc. The sawing parameters are the linear speed of the saw blade, the cutting depth and the feed speed. The linear speed of saw blade: In actual work, the linear speed of a diamond circular saw blade is limited by equipment conditions, the quality of the saw blade and the nature of the stone being sawed. From the perspective of the best saw blade service life and sawing efficiency, the linear speed of the saw blade should be selected according to the properties of different stone materials. Sawing depth: Sawing depth is an important parameter involving diamond wear, effective sawing, force on the saw blade and the properties of the stone being sawed. Generally speaking, when the linear speed of the diamond saw blade is high, a small cutting depth should be selected. When the linear speed of the diamond saw blade is large, a large depth of cut should be selected. However, when the performance of the saw machine and the strength of the tool allow, the cutting depth should be taken as far as possible to improve the cutting efficiency. When there is a requirement for the machined surface, a small depth cut should be used. Feed speed: The feed speed is the feed speed of the stone being sawed. Its size affects the sawing rate, the force of the saw blade and the heat dissipation from the sawing. Its value should be determined according to the nature of the stone being sawn. Generally speaking, when sawing soft stone, the cutting depth can be increased and the feed speed can be reduced, which is more conducive to improving the sawing rate. When sawing fine-grained stone, the feed speed can be appropriately increased. If the feed speed is too low, the diamond blade will be easily ground. However, when sawing coarse-grained stone, the feed speed should be reduced, otherwise, it will cause the saw blade to vibrate and cause the diamond to break and reduce the sawing rate.
