Abstract

The invention relates to a grinding wheel production process. The grinding wheel production process comprises the following steps of tool bit material proportion setting, tool bit raw material mixing,tool bit cold press molding, tool bit hot press sintering, tool bit finished product treatment, matrix casting molding, matrix quenching, matrix electrolysis and matrix tempering. The manufactured tool bit has excellent mechanical performance, the improvement of the grinding quality in a grinding operation and the service life of the tool bit is facilitated, the bonding strength of the tool bit and a base body reaches the standard, and the use requirement can be met. A grinding wheel manufactured according to the process has high strength, good abrasion resistance and excellent heat dissipation performance, and therefore, the service life of the grinding wheel is prolonged.

Description

technical field [0001] The invention relates to the technical field of grinding wheel products, in particular to a grinding wheel production process. Background technique [0002] Grinding wheel is the most widely used type of abrasive tools. It rotates at high speed when used, and can be used for rough grinding, semi-finishing and Fine grinding as well as grooving and parting off etc. [0003] However, due to the low strength of the existing grinding wheel, it is easy to deform, and at the same time, it is easy to slip during the grinding process, resulting in unstable and unreliable grinding of the grinding wheel, weak grinding force, and weak structure, which not only grinds the workpiece Processing brings great potential safety hazards, and also seriously affects the grinding accuracy of the workpiece, which cannot meet the grinding requirements of the product. At the same time, the service life is short, the grinding efficiency is low, and the range of workpieces that ...
