Abstract:
A machine tool comprising:a rack (2) defining an inner space (3), and comprising a front side (5) positioned in an x-y plane; an x skid (7) and a y skid (13), the x skid (7) having a rear side (9) facing the front side (5), and a face side (11) turned away from the rear side (9) and assigned to an operating side (4); x guides (6, 8) mounted on the rack (2) on the one hand, and on the x skid (7) on the other, and allowing a displacement of the x skid (7) relative to the rack (2) in an x direction; y guides (12, 14) mounted on the x skid (7) on the one hand, and on the y skid (13) on the other, and allowing a displacement of the y skid (13) relative to the x skid (7) in a y direction; a tool spindle (20) arranged in the y skid (13) and extending in a z direction (3); x linear motors (23) arranged on the front side (5) of the rack (2) on the one hand and on the rear side (9) of the x skid (7) on the other, each comprising a primary part (27) and a secondary part (24), and each comprising an air gap (37) between the primary part (27) and the secondary part (24), wherein the air gaps (37) of the x linear motors are arranged in a common x-y plane; and y linear motors (30) arranged mirror-symmetrically relative to a central y-z plane (22) of the x skid (7) and further arranged on the face side (11) of the x skid (7) on the one hand and on the rear side (15) of the y skid (13) on the other, each comprising a primary part (34) and a secondary part (31), and each comprising an air gap (38) between the primary part (34) and the secondary part (31), wherein the air gaps (38) of the y linear motors (30) are arranged in a common x-y plane.
