Abstract
A system, apparatus and method capable of grinding and polishing fabricated vertical surfaces of varying shapes and sizes without the use of hand tools. The system comprises a frame which can be affixed to the surface and which supports a grinding and polishing apparatus. The grinding and polishing apparatus uses air pressure to force a rotating grinding or polishing disc against the surface being worked on. The frame is designed so that the grinding and polishing apparatus can be moved (via, e.g., tracking) both vertically and horizontally to any desired point within the frame. The grinding and polishing apparatus optionally includes a water nozzle and vacuum system to spray and recapture water used to cool the surface being operated on.
Claims16
An apparatus for grinding or polishing a surface, comprising:
- an open-ended hollow body;
- a motor assembly in the hollow body set against at least one stand in a forward portion of the body by a counterforce mechanism;
- a grinding or polishing disc attached to a forward end of the motor assembly and set in the open end of the hollow body, the grinding or polishing disc being adapted to be rotated by the motor assembly to grind or polish the surface;
- an air stop attached to the rear of the motor to form an air chamber in the rear of the hollow body;
- and
- a compressed air hose attached to the rear of the hollow body adapted to increase air pressure in the air chamber and thereby force the motor assembly and grinding or polishing disc forward against the surface to be polished.
A system for grinding or polishing a vertical or sloped surface, the system comprising:
- a frame adapted to be affixed to the vertical or sloped surface, the frame comprising at least two tracked vertically oriented rails, and a horizontally oriented rail mounted in the vertically oriented tracks;
- and
- a grinding or polishing device mounted to the horizontally oriented rail, the device comprising a rotatable grinding and polishing disc, wherein compressed air is used to press the grinding and polishing disc against the vertical or sloped surface, said grinding or polishing device comprising:
- a motor assembly in a hollow body of said device and being set against at least one stand in a forward portion of the body by a counterforce mechanism,
- the grinding or polishing disc being attached to a forward end of the motor assembly and set in an open end of the hollow body, the disc being adapted to be rotated by the motor assembly to grind or polish the surface, and
- an air stop attached to a rear of the motor to form an air chamber in the rear of the hollow body.
