The influence of temperature on saw blade processing is mainly reflected in two aspects:
First, it causes graphitization of diamond in agglomerates;
Secondly, the thermal forces between the diamond and the matrix cause the diamond particles to fall off prematurely.
New research shows:
The heat generated during the cutting process is mainly transferred into the agglomeration. The temperature in the arc zone is not high, generally between 40 and 120°C. The temperature at the abrasive grinding point is relatively high, generally between 250 and 700°C.
The coolant only reduces the average temperature of the arc zone and has little effect on the temperature of the abrasive particles. Such temperatures will not cause graphite carbonization, but will change the friction properties between the abrasive particles and the workpiece, and generate thermal stress between the diamond and additives, causing fundamental bending of the diamond failure mechanism. Research shows that temperature effects are the biggest factor causing saw blade breakage.
