Granite saw blades often work for a long time, so the degree of wear is very large, the need for constant replacement of the blade. How to reduce the wear of the tool head?
The quality of granite saw blade itself, diamond grade, content, particle size, matching of binder and diamond, tool shape and other factors related to the tool itself are important factors affecting tool wear.
The wear degree of granite saw blade will be affected by cutting material, selected feed rate and cutting speed, and the geometry of the workpiece.
Different workpiece materials, their fracture toughness, hardness and so on are greatly different, so the workpiece material properties also affect granite saw blade wear.
The higher the content of quartz, the more severe the wear of diamond. If the content of orthoclase is obviously high, the sawing process is relatively difficult. Under the same sawing condition, the coarse-grained granite is more difficult to fracture than the fine-grained granite.
Granite saw blade is basically composed of matrix and cutter head, the matrix of the saw blade followed by diamond cutter head, driven by the cutting machine processing stone.
When we are using granite saw blade, can press cut corresponding specification to choose, near regular meeting sees a string of Numbers and letters, what do they represent after all?
Internal diameter of h-granite saw blade; L- the length of the segment; X- the height of diamond grain segments embedded in the matrix; D-granite saw blade diameter; Thickness of t-granite saw blade; E- matrix thickness.
For granite saw blade design parameters, the country has standards. First, the outside diameter of the saw blade is determined. After the outside diameter is determined, other parameters are also determined. Granite saw blade groove has three forms of wide water tank, narrow water tank, keyhole groove.
Practice makes perfect, and it is easy to see the meaning of a string of Numbers and the “mother” on a granite saw blade.
