<p>A metal workpiece finishing machine has a pair of upper and lower rotary shafts (4,5) each having an integral eccentric (4a,5a). These are mounted in an operation member (3) which is provided with a pair of circular through holes (3a,3b) in which the eccentrics (4a,5a) are received. The rotary shafts (4,5) are connected to an electric motor through a transmission mechanism (14,13a,13b,4b,5b). A cutting tool (30) with a V-cross-section edge is detachably mounted in a recess (3c) on the upper surface of the operation member. The arrangement is such that a circular motion is imparted to the edge of the tool. A metal workpiece is longitudinally fed along a base, with the tool motion causing a workpiece corner to be machined.</p> |
