ABSTRACT:
Particularly compact facing head structure including a housing having an axis of rotation and adapted to be directly secured to a rotating spindle for rotation about the axis of rotation thereof, slides secured to an end face of the housing for movement transversely of the axis of rotation of the housing, an actuating member positioned within the housing for movement axially thereof having external helical cam teeth thereon, an axially fixed cam member positioned between the housing and actuating member for rotation relative thereto having internal helical cam teeth engaged with the helical cam teeth on the actuating member whereby an axial movement of the actuating member relative to the housing the cam member is rotated angularly with respect thereto, and slot and pin mechanisms operable between the slides and cam member for moving the slides transversely of the axis of rotation of the housing on rotation of the cam member, which facing head extends a minimum distance beyond the mounting face of the spindle.
One end of the actuating member may extend through the end face of the housing so that a boring tool may be secured to the end of the actuating member whereby simultaneous boring and facing operations may be accomplished with the facing head. The slides are spring biased in one direction in all positions thereof by means of a helical spring operable between a bolt in the slides and a pin in the housing to compensate for centrifugal force, backlash and facing head wear.
Structure is provided for lubrication of the facing head under predetermined pressure with the facing heat rotating. Passages are provided in the facing head for passing coolant to a workpiece through the head.
