ABSTRACT:
Cutting apparatus having a ram axis gear tube (32) equipped with internal threads engageable with external threads (48) of a main shaft (42). A tool can be fixed to the main shaft (42). The external threads (48) of the main shaft (42) are formed on external splines (44). A main shaft rotation gear (46) has internal splines (41) mating with the external splines (44) of the main shaft (42). Rotation of the ram axis gear tube32thus causes the main shaft (42) to move axially via the internal and external threads. Rotation of the main shaft rotation gear (46) causes rotation of the main shaft (42). The tool fixed to the main shaft (42) can thus undergo axial and rotational movements. A motor (74) can be coupled to main shaft (42) and a motor shaft (63) extended through the ram axis gear tube (32) and the main shaft (42). The motor shaft (63) can drive a linear gear (68) of a cross slide assembly (24) and thus radially move a tool fixed to the cross slide assembly (24).
