Turret-type machine tool

A turret-type machine tool comprising

• a workpiece support (1, 010), rotatably supported for rotation about a vertical tool switching axis (6, 60) and indexable incrementally by a step-drive,
• said workpiece supports (1, 010) being lockable in stationary position in individual machining stations (A, B, C) in accordance with respective angular positions,
• said workpiece support (1, 010) being formed with at least one pair of side surfaces (9, 90) positioned opposite each other, with respect to said tool switching axis (6, 60), and extending parallel to each other;
• at least two workpiece holders or receptors (10, 100) located on the workpiece support (1, 010), said workpiece holders or receptors being formed as circular rotatably supported tables, rotatable about their own axis and each defining a planet axis (11, 10);
• switching or drive means (13, 130) coupled to the workpiece holders or receptors (10, 100) for rotating the respective holders or receptors about their own planet axis (11, 110);
• machining units (22, 220) assigned to the respective machining stations (A, B, C), said machining units being located laterally of the workpiece support (1, 010),
• at least one machining unit having at least one machining spindle (38, 380), which spindle can be positioned in the direction of the workpiece support (1, 010),
• wherein the planet axes (11, 110) of the workpiece holders (10, 100) are
• located in at least one horizontal plane (12, 120),
• two of said planet axes being aligned as a pair parallel to each other,
• are spaced by equal distances from the vertical tool switching axis (6, 60), and
• extend at a tangent to a theoretical circle having the tool switching axis (6, 60) as its center;
• and
• wherein the workpiece holders or receptors (10, 100) are located at opposite side surfaces (9, 90) and facing in opposite directions with respect to said pair of side surfaces of the workpiece support (1, 010).
