A preparation method for a single-layer brazing diamond grinding wheel

Abstract

A preparation method for a single-layer brazing diamond grinding wheel comprises the following steps: a. performing rust removal and polishing to a surface of a grinding wheel base body, and then performing alcohol flushing; b. applying a solder layer on the surface of the base body and applying a silver solder layer on a surface of the solder layer; c. cleaning the diamonds with a dilute sulfuric acid and rinsing in ionized water and drying; d. scattering the dried diamonds on the surface of the solder layer and performing brazing treatment by brazing heating equipment, and adding a small amount of carbide in the brazing process. The single-layer brazing diamond grinding wheel manufactured by the invention can enable the grinding material bare height to reach 70-80 % of the grinding material height, and the chip space among the grinding materials is greatly expanded and is not easy to block. More cutting blades are used for efficiently grinding materials and are sharper. The specific grinding energy can be greatly reduced. The heat generated by grinding away each unit volume of metal is decreased. The large chip space can efficiently hold more grinding fluid, so that the grinding temperature is greatly reduced and the grinding burn injury can be efficiently prevented.

AI Technical Summary

Problems solved by technology

The most important thing is that the bonding strength is not high. The coating metal on the electroplated grinding wheel is not a binding agent in the strict sense of the abrasive industry. There is no firm metallurgical chemical bond at the interface between the coating metal, the substrate and the abrasive, and the abrasive is actually just It is mechanically embedded in the plated metal, and the holding force is not strong. In the high-efficiency grinding with heavy load, the grinding wheel is prone to failure due to abrasive grain falling off.

In order to increase the holding force, the plating thickness must be increased, resulting in a reduction in the exposed height of the abrasive grains, a relatively reduced space for chips, easy clogging of the grinding wheel, poor heat dissipation, and burns on the surface of the workpiece.
