Mounted flap wheel – bore polisher

Bore polisher

Bore polisherThe 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 featuresConforms to contours due to high flexibility.Consistently high stock removal rate throughout the entire service life as new, aggressive abrasive is constantly exposed.ApplicationsCleaningDeburringStep-by-step fine grindingGrinding outLevelingRemoving oxide layersSurface workWork on weld seamsMaterials that can be workedStainless steel (INOX)Steel materials with a hardness > 54 HRCSteels up to 370 HV (< 38 HRC)AluminumBrassCast steelCopperGrey/nodular cast iron (GG/GJL, GGG/GJS)Hardened, heat-treated steels over 370 HV (38 HRC)Recommendations for useFlap 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.SafetyFor 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.Technical informationDia.
