Description

Resinoid-bonded CBN grinding discs are often used for grinding tungsten carbide or HSS tools, as well as for other production grinding processes. They are used in both wet and dry grinding.

Phenolic resin bond for high-performance dry grinding. The PHT bond is designed for dry grinding and allows cool grinding, even without coolant.

Advantages

The characteristics of the resinoid bond can be optimally adjusted to the application.
Easy to dress.

Recommendations for use

A larger diameter D allows greater economic efficiency thanks to the improved thermal and kinematic conditions.
Always select a coating width, W or U, that is narrower than the workpiece to be ground.
If possible, wet grinding is to be preferred to dry grinding. This reduces tool wear and the risk of thermal damage to the workpiece. Bonds that are designed for dry grinding may, in exceptional circumstances, also be used for wet grinding.
A larger abrasive coating thickness, X, affects the material cost for CBN and the bond. It has only little influence on production costs, however. A greater abrasive coating thickness, X, is therefore generally more economical.
