The flaps made of coated abrasive are arranged radially around the axis in a fan-type structure. Designed for fine grinding. 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.
Applications
- Cleaning
- Deburring
- Step-by-step fine grinding
- Grinding out
- Leveling
- Removing oxide layers
- Surface work
- Work on weld seams
Materials that can be worked
- Stainless steel (INOX)
- Steel materials with a hardness > 54 HRC
- Steels up to 370 HV (< 38 HRC)
- Aluminum
- Brass
- Cast steel
- Copper
- Grey/nodular cast iron (GG/GJL, GGG/GJS)
- Hardened, heat-treated steels over 370 HV (38 HRC)
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
- 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.
