Diamond bit is an ideal tool for drilling non-ferrous materials. The diamond grinding wheel is made of diamond abrasive, which is bonded with metal powder, resin powder, ceramic and electroplated metal respectively. The circular bonded grinding tool with through hole in the center is called diamond grinding wheel (alloy grinding wheel). Compared with the copper electrode, the diamond electrode has the advantages of low electrode consumption, high machining speed, good machining performance, high machining accuracy, small thermal deformation, light weight, easy processing, high temperature resistance, high machining temperature, adhesive electrode and so on, as well as the structure parameters of the drill bit（ For example, the thickness of the core, the shape of the chip removal groove and the helix angle determine the rigidity and strength of the bit, Through a large number of scientific tests on the machining characteristics of diamond materials, para tool optimizes the geometric angle of related tools, so that the overall cutting performance of the tool is greatly improved.
When designing and selecting diamond bit, it is very important to determine these parameters reasonably for improving the structure, cutting performance and efficiency of diamond bit. The diamond grinding wheel is made of diamond abrasive, which is bonded with metal powder, resin powder, ceramic and electroplated metal respectively. The circular bonded grinding tool with through hole in the center is called diamond grinding wheel (alloy grinding wheel).
There is essential difference between the angle of diamond coated tool and that of common coated tool, so when designing diamond coated tool, due to the graphite (chemical formula C ）Due to the particularity of processing, its geometric angle can be properly enlarged, and its cutting groove can be enlarged, which will not reduce the wear resistance of its cutting edge. CBN, PCD, PCBN, diamond wire mould, diamond saw and bit products are its representatives. The hardness of diamond grinding wheel determines the main characteristics of diamond grinding wheel. It can grind hard materials such as hard alloy, glass and ceramics efficiently, and the grinding tool has a long service life.
