Description

With mounted flap wheels, coated abrasive flaps are arranged radially around the core in a fan-like structure. The flexible flaps perfectly adapt to surface contours. The abrasive grain is embedded in the sturdy, flexible cloth backing material with a resinoid bond.

In ISO 3919, mounted flap wheels are designated as "flap wheels with shaft."

For coarse grinding work with a high stock removal rate and cool grinding. Active grinding additives in the coating substantially improve the stock removal rate, prevent loading and result in cooler grinding.

Special features

Conforms to contours due to high flexibility.
Consistently high stock removal rate throughout the entire service life as new, aggressive abrasive is constantly exposed.
Can be used face-down very close to edges and in corners due to the flat, molded-core design.

Recommendations for use

Flap wheel wear and the thermal load on the workpiece are reduced by decreasing the contact pressure and peripheral speed, and by adding grinding oil.
Stock removal rate should be increased by using a coarser grit, not by increasing the contact pressure. This avoids unnecessary flap wheel wear and prevents the thermal load of the workpiece.
Increasing the speed results in a slightly finer surface quality. An increase in contact pressure results in a slightly coarser surface. The softer the workpiece material, the coarser the resulting surface (when using the same grit size).
For the best performance, use with a recommended peripheral speed of 3,000-4,000 SFPM. This provides an ideal compromise between stock removal rate, surface quality, thermal load on the workpiece and tool wear.
Use the appropriate grinding oil for the material to significantly increase the service life and the abrasive performance of the discs.

Safety notes

For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.
The contact pressure has to be reduced significantly when the optimum rotational speed is exceeded.
Ensure the clamping depth is at least 5/8" and the specified maximum rotational speed is not exceeded with unsupported shank lengths.
