In order to make the diamond saw blade have a longer service life and higher work efficiency, we must minimize the wear of the diamond saw blade. Next, the diamond saw blade manufacturer will tell you how to reduce the wear of the diamond saw blade.
The quality of the diamond saw blade head itself is an important factor that affects the tool wear. Factors related to the tool itself, such as diamond grade, content, particle size, the matching of the binder and the diamond, and the tool shape, are important factors that affect the tool wear. The wear of the diamond saw blade tip is affected by the material being cut, the feed rate and cutting speed selected, and the geometry of the workpiece.
Different workpiece materials have large differences in fracture toughness and hardness, so the properties of workpiece materials also affect the wear of diamond tools. The higher the quartz content, the more severe the diamond wear; if the content of orthoclase is significantly higher, the sawing process is relatively difficult; under the same sawing conditions, the coarse-grained granite is better than the fine-grained granite. Cleavage fractures are more difficult to occur.
We also need to know some knowledge about the use of saw blades
Linear speed of saw blade: In actual work, the linear speed of 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 service life of the saw blade and the sawing efficiency, the linear speed of the saw blade should be selected according to the properties of different stones. When sawing granite, the linear speed of the saw blade can be selected within the range of 25m to 35m/s. For granite with high quartz content that is difficult to saw, the lower limit of the linear speed of the saw blade is appropriate. When producing granite tiles, the diameter of the diamond circular saw blade used is small, and the linear speed can reach 35m/s.
Feed speed: The feed speed is the feed speed of the stone being sawed. Its size affects the cutting 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 being sawn.
Generally speaking, when sawing soft stone, such as marble, the feed speed can be appropriately increased. If the feed speed is too low, it is more conducive to improve the sawing rate. When sawing fine-grained and relatively homogeneous granite, the feed speed can be appropriately increased. If the feed speed is too low, the diamond blade will be easily ground. However, when sawing granite with a coarse-grained structure and uneven hardness, 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. The feed speed for sawing granite is generally selected within the range of 9m to 12m/min.
