machine tool with a linear motors driven by a functional unit

摘要

A machine tool has an operating unit that can be moved by at least one linear motor (24) along a first guide structure in the direction of a first axis of travel (z-axis) and by at least one second linear motor (21, 22) jointly with the first guide structure along a second guide structure in the direction of a second axis of travel (y-axis). Each linear motor (21, 22, 24) includes primary elements as well as secondary elements (15/1, 17; 15/2, 17; 23). The secondary element(s) (23) associated with the first axis of travel (z-axis) is/are operatively connected to the operating unit; the secondary element(s) (15/1, 17; 15/2, 17) associated with the second axis of travel (y-axis) is/are operatively connected to the second guide structure; and the primary elements associated with the different axes of travel (y-axis, z-axis) are operatively connected to the first guide structure and are positioned between the secondary elements (23) associated with the first axis of travel (z-axis) and the secondary elements (15/1, 17; 15/2, 17) associated with the second axis of travel (y-axis). The primary elements associated with the different axes of travel (y-axis, z-axis) are arranged in a linear side-by-side array in the direction of one axis of travel (y-axis) while mutually overlapping in the direction of the other axis of travel (z-axis).
