Flap wheel Ø40xH20mm grit 240 aluminum shank Ø 6 mm PFERD

Corundum A · with abrasive flaps on backing material · for universal use from coarse to fine grinding · Shank Ø 6 mm · Also suitable for processing brass, copper and zinc · Shank Ø: 6mm · Drive type: flexible shaft drive, straight grinder · Recommended application: Reducing contact pressure and peripheral speed and adding grinding oil reduce tool wear and workpiece temperature load. An increase in removal rate should be achieved by using a coarser grit and not by increasing the contact pressure, in order to prevent unnecessary tool wear and temperature load on the workpiece. For best performance, use at a recommended cutting speed of 15–20 m/s. This achieves an ideal compromise between removal rate, surface quality, workpiece temperature load, and tool wear. Use grinding oil suitable for the material to significantly increase the service life and grinding performance of the tools. Increasing the cutting speed results in a slightly finer surface. Increasing the contact pressure makes the surface slightly coarser. The softer the material to be machined, the coarser the surface (when using · Materials that can be machined: steel materials with a hardness > 54 HRC, aluminum, malleable cast iron, brass, cast steel, copper, gray/nodular cast iron (GG/GJL, GGG/GJS), stainless steel (INOX), steels up to 1,200 N/mm² (< 38 HRC), hardened, tempered steels over 1,200 N/mm² (< 38 HRC) · Machining tasks: equalization, weld seam processing, texturing (matting, linear matting and satin finishing), stepwise fine grinding, deburring, surface processing · Width: 20mm · Note: PFERDERGONOMICS recommends flap wheels to sustainably reduce vibration and noise generated during use and to improve working comfort. · Length, shank: 40mm · RPM, opt.: 9600RPM · Safety instructions: For safety reasons, the specified maximum permissible speed must never be exceeded. The contact pressure must be significantly reduced if the specified optimum speed is exceeded. Safety is only guaranteed if the clamping length is at least 15 mm and the specified maximum speed is not exceeded for open shank lengths. · Advantages: Optimal contour adaptation due to high flexibility. Frontal use very close to edges and in corners possible due to flat core construction. Consistently high material removal over the entire service life, as new, aggressive abrasive is continuously released.
