Document Type and Number:
Japanese Patent JP2916937
Kind Code:
B2
Abstract:
A grinding method is provided which is capable of uniformly and precisely grinding objects in a short time, softening shocks produced when the rotation of a grinding barrel is changed between the forward direction and the backward direction to thereby eliminate bruises of the surface of grounded objects, coping with grinding for a large number of objects to be ground in a small quantity or a heavy-weight or a large-size object to be ground, and preventing contacts and collisions between objects to be ground. The grinding method comprises the steps of rotatably mounting not less than one grinding barrel (8) at locations away from the central axis (3) of a rotary drum (2), enclosing a grinding material and objects to be ground in the grinding barrels (8), rotating the grinding barrels (8) in the directions identical to and opposite to the direction in which the rotary drum (2) is rotated, and grinding the objects to be ground. A grinding apparatus for implementing the above-mentioned method is also provided.
