The content of diamonds in the grinding rim depends on the application.

 

When a good surface finish is demanded lower concentrations (20 - 50) in combination with finer diamond powder are required.

 

Where rapid stock removal of tungsten carbide or hardened steel is intended a concentration of 75 to 125 is usually selected.

 

Concentrations of up to 150 are used for profile grinding wheels and cylindrical wheels which have a small contact area.
