A diamond grinding wheel is a rigid grinding tool made from diamond abrasives combined with metal powder, resin powder, ceramics, or electroplated metal as the bonding agent. It is a circular bonded abrasive tool with through-holes.

 

The following describes the grinding methods of diamond grinding wheels.

 

 

This method has relatively low working efficiency, but the grinding quality is very good, with lower surface roughness compared to similar products. During grinding, the diamond grinding wheel rotates at a very high speed.

 

The worktable performs a compound longitudinal movement, and during each operation or processing cycle, the diamond grinding wheel receives one compensation. Any remaining material is removed during the grinding process.

 

 

This method offers significantly higher efficiency, but also has its drawbacks. The grinding force is very large, and the grinding temperature is relatively high, so sufficient coolant must be supplied during grinding.

 

The rotation of the diamond grinding wheel provides the main driving force. The combined rotational motion of the spindle and the wheel enables continuous compensation.

 

In this method, the worktable does not perform longitudinal movement. The width of the diamond grinding wheel is greater than the grinding width, and grinding continues until it reaches the required specification.

 

 

This method combines the two approaches mentioned above. Combined grinding offers higher efficiency, better quality, and other advantages. In this process, a segmented grinding method is used for rough grinding of the workpiece, followed by fine grinding of the remaining portion using a grinding wheel.

 

 

This method offers very high production efficiency, but the dressing technique for diamond grinding wheels is relatively complex. It also requires high structural rigidity of the workpiece and sufficient allowance for wheel entry and exit.

 

During grinding, the entire section of the diamond grinding wheel forms a stepped profile. The feed speed of the workpiece is very slow.

 

The remaining material after deep grinding is removed using longitudinal grinding.
