In actual operation control, the grinding wheel is prone to edge breakage during cutting in and out:

When cutting a grinding wheel with a tool with a larger main deviation angle, the edges are prone to collapse at the cut in and out points. The diamond grinding wheel operating layer, also known as the diamond layer, is composed of abrasives, binders, and fillers, and is the operating part of the grinding tool. The transition layer, also known as the non diamond layer, is composed of a binder, metal powder, and filler, and is the part that firmly connects the diamond layer to the substrate.

To address this issue, a circular blade was selected and the main deviation angle was changed to make the cut and exit smooth. When the feed rate is 1 to, there is no edge collapse phenomenon.

The chips are in powder form:

The chips from cutting the grinding wheel are in powder form, and the wear of the cutting tool is mainly caused by the wear of the rear cutting surface, which mainly bears the wear of the diamond grinding wheel abrasive. Diamond grinding wheel is a circular solid grinding tool with a through hole in the center, made from diamond abrasive as the raw material and metal powder, resin powder, ceramics, and electroplating metal as the bonding agent. It has the advantages of high strength, good heat resistance, sharp cutting, high grinding efficiency, less heating and blockage during the grinding process, and low thermal expansion.

Low cutting force and cutting temperature:

Diamond composite sheets have a high thermal conductivity, which is~9 times that of hard alloy and 2-6 times that of copper, allowing the temperature in the cutting area to quickly spread out. Diamond grinding wheel is a circular solid grinding tool with a through hole in the center, made from diamond abrasive as the raw material and metal powder, resin powder, ceramics, and electroplating metal as the bonding agent. It has the advantages of high strength, good heat resistance, sharp cutting, high grinding efficiency, less heating and blockage during the grinding process, and low thermal expansion.

Therefore, the temperature of cutting resin bonded or ceramic bonded grinding wheels with diamond composite cutting tools is many times lower than that of cutting metal.

Compared to traditional turning, diamond composite discs have almost no dust flying during the cutting process, and the noise is effectively reduced. The working environment of diamond grinding wheels has been further improved
