Designed for universal work on medium-sized and large metal surfaces, e.g. fine grinding work on large radii in container, kitchen, and appliance construction, and achieving uniform finishes (grinding patterns) on large surfaces and contours in manual applications. Designed for all conventional keyway systems.
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
- Deburring
- Step-by-step fine grinding
- Leveling
- Structuring (matt finishing, brush matting and satin finishing)
- Surface work
- Work on weld seams
Materials that can be worked
- Steel materials with a hardness > 54 HRC
- Steels up to 370 HV (< 38 HRC)
- Aluminum
- Annealed cast iron
- 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 3,000-6,000 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.
- For the best results, use a power tool with 1,000–1,500 watts.
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.
- The maximum permitted peripheral speed is 6,300 SFPM.
