Abstract: The process of fine boring
machining of piston pin bore is concerned as an important point for quality
control.Machining quality has a big effect on the pistons performance and
compression height and Diameter Of pin bore are the key dimensions.This paper
mainly introduces the improvement of fixture used for fine boring of piston pin
and the method of temperature control,which updates the ability of fine boring
greatly.
