A pipe machining apparatus includes a frame, a tool support, an advancement device, and an advancement member. The tool support is coupled to and movable relative to the frame. The tool support is adapted to support a tool and move the tool in a direction toward a pipe at an increment. The advancement device includes an advancement projection fixedly attached to the frame. The advancement projection includes a contact-surface. The advancement member is coupled to the tool support. Upon the advancement member contacting the contact-surface of the advancement projection the advancement member is adapted to advance the tool towards the pipe at the increment. The contact-surface of the advancement projection is shaped to always be in a non-perpendicular contact position with the advancement member.

A rotating machining device for machining a work piece includes a body having a support housing and a headstock rotatable relative to the support housing. A tool module is mounted to the headstock that includes a tool feed system and an actuating assembly is attached to the support housing. The actuating assembly is arranged to collide with and actuate the tool feed system at a collision point. The radial position of the collision point is adjustable relative to the tool module such that the collision point is repositionable independent of the tool module.
