Abstract
A linear blind broaching machine (10) includes a base (22), a broaching ram assembly (24), a linear tool slide (26) supported on the base by linear antifriction bearings (90) and a support block (92) mounted between the base and the linear tool slide below a broaching ram of the broaching ram assembly to provide support to the linear tool slide during blind broaching. The linear tool slide has an elongated construction including an elongated positioning block (114) against which blind broaches are laterally positioned, and an electric servomotor (108) drives the linear tool slide (26) to provide indexing thereof between broaching movements of the broaching ram. A roller screw drive (54) driven by an electric servomotor (56) drives a broaching ram (44) supported by linear antifriction bearings 46.
