Polishing or grinding device i.e. pressurized air power tool, for polishing or grinding coated surface i.e. motor car part, in automobile industry, has pressurized air guide device comprising work spindle rotatable in air guidance cup

摘要

The device (1) has a pressurized air guide device connected between a multi-disk motor (4) and a polishing pad (2) or a grinding element. The polishing pad and/or the grinding element is formed with air ducts (29) in a region of a lower surface (3) for discharging driving pressure air (7) from a middle area of the lower surface of the polishing pad and/or the grinding element to a peripheral edge (30) of the polishing pad and/or the grinding element. The pressurized air guide device comprises a hollow work spindle (6) rotatable in an air guidance cup (20).
