Flap Wheels with hole most widely used in industry.
   These wheels are produced with diameter 120...400mm and are mainly installed on stationary equipment.
   Sets of flap wheels in the form of rollers for grinding and polishing billet surfaces are used in special automated machines cutlery working employ.
   Grinding and polishing of external and internal surfaces of stainless steel and aluminum utensils are conducted on special machines for obtaining matte or mirror surfaces.
   Round grinding machines allow the use of flap wheels for "longitudinal" external grinding of cylindrical and conic surfaces of billets whose length exceeds the wheel height (rollers, cases, etc.) and for "in feed" external grinding for cylindrical, conic, stepped and profile surfaces (flanges, pins of crankshafts, axles, pivots, ball pegs, etc).
   A universal non-center grinding machine is most effective to use for polishing cylindrical, conic, profile surfaces for mass and large-scale production, especially for manufacturing consumer (tubular billets for children's strollers, lighting equipment, bicycles, cornices, and etc.). For this sets of 2 or 3 different-grit flap wheels are mounted.
   Flat grinding machines are used for polishing of surfaces of thin-wall billets, processing of shaped and profile surfaces as well as
