Document Type and Number:
Japanese Patent JPS58219017
Kind Code:
A
Abstract:

PURPOSE: To uniformly finish a molded object with good accuracy, by a method wherein a molded object of rotary body shape is held with a holder capable of freely being driven by rotation, the molded object being rotated around its central axis by rotating the holder and it is deburred by allowing an edged tool to abut against the burr sticking surface of molded object.

CONSTITUTION: The molded object 1 of rotary body shape is put on a base 5, and the molded object 1 is pinched between the top and bottom pinching bodies 10 and 8 and floated from the base 5 at the same time by raising a rotary shaft 7. At that time, because the central axis of molded object 1 was caused to concur with the center of rotary shaft 7, the burr sticking surface of molded object 1 is rotated in a surface perpendicular to the rotary shaft 7 by rotating the rotary shaft 7. After rotation, the burr 4 is slowly deburred during raising the edged tool 3, the edged tool 3 being stopped when the tip of edged tool 3 reaches the finish final surface, and the deburring operation is finished. Thus, the uniform finish with good accuracy can be obtained, and there are no defects such as clogging, etc., according to the use of edged tool.
