PURPOSE:To provide a flat ground surface by soaking a grinding cylinder with side holes fixing a processed article on its peripheral surface in a grinding tank filled with grinding liquid, sucking out the grinding liquid from the bottom part of the grinding cylinder, concentratively flowing the grinding liquid again and generating a vortex along the peripheral surface of the grinding cylinder. CONSTITUTION:A proper amount of grinding liquid 3 is filled in a grinding tank 2, a grinding cylinder 1 with a processed article previously fixed on its inner peripheral surface is soaked and fixed in the grinding tank 2, the grinding liquid 3 is sucked out from a conduit 5 connected to the lower part of the grinding cylinder 1 and again percolated to the upper part of the grinding tank 2. Consequently, a vortex is generated inside of the grinding cylinder 1, and the lengthy surface of the processed article fixed on the inner peripheral surface of the grinding cylinder 1 is exposed to the accelerated grinding liquid 3 and ground. In the meantime, the processed article particulates ground and liberated are separated, filtered and removed on the way of circulation by a liquid pump 4 installed with separator and filter functions. When the grinding liquid 3 is sucked out from the conduit 5 connected to the lower part of the grinding cylinder 1, the grinding liquid 3 in the grinding tank 2 flows out downstream while revolving in high speed as a vortex curved by a fin provided on the outer peripheral surface of the grinding cylinder 1 in the vortex revolving direction. |
