A fixed spindle for fixing the polishing tool is swingably connected to the joint shaft that moves forward and backward as the crankshaft rotates, and the main arm, on which this fixed spindle is attached so that it can move forward and backward, is attached to the mounting body. The main arm is rotatably connected via a rotation shaft, and the main arm is connected and fixed to a rotating swing piece via a rotation shaft, and the main arm is connected to the eccentric shaft for eccentrically rotating the swing piece. A second electric motor for pendulum movement, which is separate from the first electric motor, is connected to make the swing piece move in a pendulum manner.

の形状に合わせた研磨加工が可能となる。The polishing tool is moved forward and backward by the rotational force of the first electric motor, and the spindle on which the polishing tool is fixed is moved to the second motor.
By causing the main arm to swing in a direction that intersects the forward and backward movement axis using the rotating force of the motive, the polishing tool is reciprocated and swings in a direction that intersects with the reciprocating direction axis. The oscillating motion and oscillating motion are performed by first and second separate electric motors, and by arbitrarily selecting the ratio of the motion speed of the reciprocating motion and the oscillating motion, the trajectory of the polishing tool can be changed to a straight line, circle, ellipse, or low profile. Glue surge figures, etc. can be freely set from next to higher order, so the contact area between the polishing tool and the workpiece is not concentrated in one part, and there is no groove layer, making it extremely unlikely to cause scratches or uneven wear. It is possible to perform a polishing process with a smaller amount and in accordance with the shape of the polished part.

固定した固定スピンドルを同時に進退運動させる。To explain the operation of the present invention more specifically, when the first electric motor is operated, the eccentric shaft connected to the first electric motor rotates, and the crankshaft rotates eccentrically as the eccentric shaft rotates. The joint shaft connected to this crankshaft in a direction intersecting the axial direction of the crankshaft is moved forward and backward. A fixed spindle connected to this joint shaft and to which a polishing tool is fixed is simultaneously moved forward and backward.

時に行うものとなる。Further, if the second electric motor is activated at the same time as the first electric motor is activated, the eccentric shaft rotates eccentrically, causing the swinging piece connected to the eccentric shaft to perform a pendulum movement. This pendulum movement of the swing piece causes the main arm connected to the swing piece to swing. A fixed spindle is attached to the main arm so as to be movable forward and backward, and the polishing tool fixed to the fixed spindle simultaneously moves forward and backward and swings in a direction crossing the forward and backward axis.

Because of this, the contact area between the polishing tool and the workpiece is not concentrated in one part, and there is no groove layer, and scratches, uneven wear, etc. are extremely unlikely to occur, and polishing that matches the shape of the part to be polished is possible. Processing becomes possible.
