PFERD Flap grinder set F 5030/6 A. The set contains an application-oriented selection of flap sanders for universal use from coarse to fine sanding. For flap sanders, the blades made of abrasive are arranged radially around the axis of the tool on a substrate. Thanks to their flexibility, they adapt perfectly to the contours of the workpiece. The abrasive grain is embedded in a synthetic resin bond on the tensile resistant, flexible fabric backing. Flap grinders are listed in ISO 3919 under the designation "lamellar grinding pins". // Contents: 3 flap sanders with abrasive corundum A, outer diameter 50 mm, width 30 mm, shaft diameter 6 mm, 1 piece each: grain size 60, 80, 120 // Opt. RPM: 7,000 // Max. RPM: 15,200 // Machinable materials: steel, cast steel, aluminium, copper, zinc, cast iron, plastics, other materials // Machining tasks: leveling, deburring, surface processing, weld processing, structuring (matting, line matting and satinising), gradual fine grinding // Suitable tool drives: bending shaft drive, straight grinder. Recommended use: For best performance when a Recommended cutting speed of 15-20m/s. An ideal compromise between removal rate, surface quality, temperature load of the workpiece and tool wear is achieved. Use abrasive oil suitable for the material to significantly increase the service life and grinding performance of the tools. // Safety instructions: The maximum permissible speed must never be exceeded for safety reasons. The contact pressure is significantly reduced if the specified optimal speed is exceeded. Safety is only guaranteed if: the clamping length is at least 15 mm and the specified maximum speed is not exceeded with open shaft lengths.
