Abstract
A piston pin hole boring system and method of forming pin holes therewith includes fixing a piston to a fixture supported by a slide member. Then, rotating a cutting member about a first axis and moving the slide member with the fixture thereon toward the cutting member along the first axis and bringing the piston into cutting contact with the cutting member. Further, moving the fixture along second and third axes, each extending transversely to the first axis and machining the desired pin hole contours in the piston with the cutting member.
