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 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.
Application is possible for both dry and wet grinding. If possible, wet grinding is to be preferred in order to reduce tool wear and the risk of thermal damage.
Generally, the following applies: For optimum economic efficiency, select a grit size that is as coarse as possible and as fine as necessary. Influencing factors include the hardness of the material and the surface quality required.
Loaded tools can be cleaned using ultrasound. In the event of strong contamination on the coating, please clean using the sharpening block DSB 2005025 (EAN 4007220168332).
Select as large a tool diameter as possible, as this increases the amount of grit that engages the workpiece. For internal grinding, the maximum tool diameter is 3/4 of the diameter to be ground.
The longitudinal feed rate for internal grinding must not exceed 2/3 of the total width per workpiece rotation. The infeed depends on the material to be machined, the cutting speed, the stability of the tool, its holder and the tool drive.
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.
