Diamond rollers can be divided into the following categories according to how they are used:

1. Plunge-cut dressing diamond roller, that is, the diamond surface of the diamond roller is made to be consistent with the surface of the workpiece to be processed, and the grinding wheel is dressed directly by the machine tool.

2. Straight-cut grinding diamond rollers are mainly used for: grinding wheel dressing in the grinding of machine tool guide rails, general bearings, screws, valve parts and other workpieces;

3. Bevel grinding diamond rollers are mainly used in situations where the width of the grinding profile is relatively large or the end face of the workpiece needs to be grinded at the same time. During the grinding process of the workpiece, the rotation axis of the workpiece and the grinding wheel axis are tilted at a certain angle to avoid During the grinding process, burns occur on the end face of the workpiece. At the same time, it can increase the grinding surface of the grinding wheel and reduce the radial grinding force of the grinding wheel, such as the grinding of workpieces such as flange bearings and hub bearing inner rings.

4. CNC trajectory dressing diamond roller: a diamond roller that uses a standard diamond layer surface (usually arc or sharp angle) to run the grinding wheel according to the trajectory compiled by the CNC program to achieve grinding wheel dressing. Its advantage is that it can adapt to the high-precision dressing of grinding wheels when grinding various workpieces through program changes. At the same time, it has a higher service life and accuracy stability compared to single-point diamond CNC dressing.
