ABSTRACT:
A plastic grinding method under isostatic pressure, wherein, by using a container capable of increasing liquid pressure and generating vibration with supersonic waves, work-pieces to be ground and a grinding compound and grinding granules are placed in the container, the liquid pressure of the grinding compound in the container is raised to a predetermined value according to the Pascal's law, so that the high pressure grinding compound in the container can form a grinding vibration with supersonic waves, and an Blaha effect and a cavitation effect can be created thereby to lower the stress on the surfaces of the work-pieces, by these two principles, the whole work-pieces can be ground and polished exactly along the whole contours thereof with better accuracy and efficiency, and plastic shaping ability of the work-pieces can be enhanced.
