|Title||Method for cutting grinding wheel by diamond grinding wheel|
Using diamond abrasive as raw material, respectively, using metal powder, resin powder, ceramics and electroplated metal as bonding agent, the circular fixed abrasive with central through hole is called diamond grinding wheel.
First, the grinding wheel is easy to collapse when cutting in and out: When cutting the thin flat cutting disc with a tool with a large main angle, the cutting edge is easy to collapse. In order to solve this problem, a circular blade is used to change the main yaw angle, so that the cutting and cutting are smooth. When the feed amount is 1 to 1.5 mm, no chipping occurs.
Second, the chips are in powder form: the chips of the cutting wheel are powdery, and the form of tool wear is the flank wear, which mainly bears the wear of the diamond wheel abrasive.
Third, the cutting force and cutting temperature is low: the diamond composite sheet has a high thermal conductivity, 1.5 to 9 times that of the cemented carbide, and 2 to 6 times that of the copper, so that the temperature in the cutting zone is quickly transmitted. Therefore, the temperature of cutting a resin bond or a ceramic bond wheel with a diamond compact tool is many times lower than that of a cut metal.
4. With the traditional turning tools, the diamond composite sheet has almost no dust flying during the turning process, and the noise is effectively reduced. The working environment of the diamond grinding wheel is further improved, which is beneficial to the physical and mental health of the employees.
