Grit Recommendations Grit Size Materials 36 For aggressive grinding and weld removal. 60 For alloyed and low-alloyed steels, stainless steels of low tensile strength. 80 High-alloyed, stainless, high temperature and heat treatable steels, and high tensile non-ferrous steels. 120 Recommended for a fine finish of metal surfaces. A coarser grit offers the advantage of a high stock removal rate and service life. A finer grit should only be used if a compromise is necessary for surface finish vs. stock removal rate.
Power Flap discs have a unique feature in that their glass fiber backing and abrasive material wear simultaneously during the grinding operations. Therefore the grinding efficiency is not impaired and the backing disc does not damage the surface of the work-piece. Quality and performance differences are not visible during short performance tests. The excellent performance features of the Power Flap's extremely long service life and constant high stock removal rate are only evident after long use and only after the flap disc has been consumed.
Optimum Results Using Flat and Conical Wheels The choice between using a flat or a conical wheel depends on the type of application. • The flat Power Flap wheel reaches its optimum efficiency at an angle of application between 0 - 15 degrees. Points to note for good surface finish: If a lower grinding angle is possible, the flat Power Flap wheel achieves better surface finish than the conical type with the same grit size.
P-96
• The conical Power Flap wheel offers advantages when grinding with steeper angles of 15 - 25 degrees.
• When grinding stainless and high temperature steels these angles can be slightly exceeded if necessary.
