Bore polisher, 1″ x 3/4, 1/4″ shank, 120 Grit, Aluminum oxide

Technical information

Description

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

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.

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.
