されている。The cutting jig 2 is composed of an air grinder 5 which rotates at high speed by compressed air, and a rotary bar 6 made of cemented carbide attached to the tip thereof, and a U-shaped handle 7 is projectingly provided on the upper portion thereof. It is attached to the formed support frame body 8 by pressing metal fittings 9 and is supported horizontally. Further, wheels 10 are attached to the lower portions of both ends of the support frame 8 via mounting plates 11, respectively.
The molded product fixing jig 1 is configured to roll in the grooves of the two running guides 4. Furthermore, the difference in height between the lower end of the wheel 10 and the rotary bar 6 is
0 is equal to the difference in height between the surface of the traveling guide groove 4 in contact with the part of the molded product to be finished.

つこれに沿って移動させる。In order to finish the parting part using the apparatus of the embodiment thus constructed, first, a molded article 12 made of a thermoplastic resin to be finished is
The molded product fixing jig 1 is mounted so as to cover the protruding portion 3 of the molded product fixing jig 1. At this time, the inner peripheral surface of the molded product 12 is adhered and fixed so that the inner peripheral surface of the molded product 12 is closely adhered to the outer peripheral surface of the protruding portion 3 and no gap is formed. Next, the air grinder 5 is operated and the rotary bar 6 attached to the tip thereof is rotated. And
In this state, the operator grips the handle 7 and causes the wheel 10 to travel along the travel guide groove 4, so that the rotary bar 6 is brought into contact with the parting portion 13 of the molded product 12 and moved along this.
