Abstract A cross-feed facing head is described which includes a housing adapted to be mounted on a spindle for rotation therewith. Slides are mounted in transverse slideways on an end face of the housing, the slides including means for mounting cutting tools and being adapted for movement transversely to the axis of the rotation of the housing. An actuating member is axially, slideably mounted within the housing and has external helical teeth thereon. An annular year member is mounted within the housing for ro- tation about the axis thereof and this annular gear member has gear teeth on the outer cylindrical edge thereof and further gear teeth on the inner cylindrical edge thereof, these inner teeth being preferably in the form of a series of spaced and adjustable racks mounted in pockets in the inner cylindrical edge with the teeth thereof mating with the external helical teeth of the actuating member. Rotatable pinion shafts are mounted in the housing for rotation about axes parallel to the axis of rotation of the housing and each pinion shaft has at one end thereof pinion teeth mating with the outer gear teeth of the annular gear member and has at the other end thereof a spur gear which mates with a rack on one side of each slide. The gear train is indexable to allow fresh gear teeth to be moved into the work areas.
