The Stenlypol company is the sole producer of this type of discs. It is the elasticity of flap discs that dictates their exclusivity.
    There is no adequate alternative to these discs in machining of spherical, cylindrical and shaped surfaces. They also demonstrate great performance on flat surfaces, providing even and smooth junctions, leaving no cuts and other defects. They are mainly used on angular grinding machines with electric or pneumatic drives.
    Body production in automobile construction, processing of curved surfaces in aircraft construction, machining of elevator and refrigerator parts, large tanks and reservoirs, working of flat surfaces with simultaneous cleaning of welds in manufacturing sates and other metal structures - this is a short list of the use of flap conic discs in metal working.
    Flap conic discs are also used in repair and construction works, as well as in everyday life.
    They can be fabricated from a grinding cloth of different grits; from P4Q to P320, depending on specific conditions of processing.
    The recommended grinding and polishing speeds range from 18 to 35 m/s depending on the material of the processed part.
