Machining machine

Abstract

The invention relates to a machine for machining parts comprising a frame (1) and a tool spindle (2) designed to carry a tool (2a). The machine also comprises a main workpiece holder (3) designed to hold a workpiece (4), movable relative to the tool spindle, in translation along three axes X, Y, and Z that are not parallel to each other, and in rotation along an axis B, the main workpiece holder (3) being mounted on a cradle (5b) integral with a hollow shaft (5a) movable in rotation about the axis B. The machine also includes a secondary workpiece support (6) that can be actuated by control means between a position of engagement in contact with the workpiece (4) and a position of disengagement without contact with the workpiece. Remarkably, the machine also comprises a finishing unit (10) housed at least partially in the hollow shaft (5a) and extending through an opening (5c) in the cradle (5b), said finishing unit (10) comprising a sliding rod (11) movable in translation along axis B between a retracted position and an extended position, the secondary workpiece support (6) being kinematically connected to the sliding rod (11).
