Process for grinding and/or polishing surfaces

摘要

The assembly (1) to remove material from a workpiece surface (S), by grinding and/or polishing, uses abrasive particles (5) carried in a liquid (3) mostly of water. A gas (4) and especially air is fed into the liquid or its holding tank (12) through a volume control (8) by a pump (7). At the workstation, a jet (9) accelerates the flow of liquid and particles against the workpiece surface. A gas pressure is used for grinding, and no pressure is used for polishing.
