  • Multi-function machine tool which permits complex machining of long pieces
    Patent number: 5052089
    Abstract: The machine tool of the invention combines the following three features: the workpiece holder (22) rotates around an axis (C) which is referred to as horizontal turning axis and is parallel to one (X) of the three orthogonal axes (X, Y, Z), the said axis (C) overlying a table (12) the flat upper-face of which is parallel to said turning axis (C) and comprises means for fastening one or more support and/or centering means (15, 24); the toolholder (38) comprises two clamping mandrels, one for a stationary tool and the other for a rotary tool; the workpiece holder is in relation with drive means (23, 25) which confer upon it one of the three kinematics of the following kinematic group: immobilization in a given angular position, a so-called slow speed of rotation for milling operations which are not parallel to the axis (C), and a so-called high speed for the turning.
