Pin mirror milling tool fixing mechanism for milling crankshaft of internal combustion engine

摘要

The fixing mechanism for a pin mirror milling tool (21) has the main body (22) of the milling tool fitted in the inner circumferential surface of the milling tool fixing sector (23), forming an angled surface with a narrow sector (24) on the body and another angled surface with a narrow sector (25) on the tool fixing sector, which are in contact with each other. The diameter of the contact surfaces decreases in the insertion direction.
