Abstract
In a multi-axis machine tool comprising a first slide way (2a) and a second slide way (2b) set apart one from the other and extending parallel along a longitudinal axis (X), a machining station (3) delimited laterally by the slide ways (2a, 2b), a cross member (4) presenting opposite ends (4a, 4b) each coupled to a respective slide way (2a, 2b), and a machining head (5) mounted to the cross member (4) and positionable over the machining station (3), at least the cross member (4) is fashioned from a low thermal expansion material.
Claims25
A multi-axis machine tool comprising:
- a first slide way (2a) and a second slide way (2b) set apart one from the other and extending parallel along a longitudinal axis (X);
- a machining station (3) delimited laterally by the slide ways (2a, 2b);
- a cross member (4) presenting opposite ends (4a, 4b) each associated slidably with a respective slide way (2a, 2b);
- a machining head (5) mounted to the cross member (4) and positionable over the machining station (3);
- characterized in that the cross member (4), at least, is embodied in a low thermal expansion material (LTEM);
- wherein the cross member is slidably actuated by a linear motor including a magnet that is positioned adjacent a layer of resilient material able to absorb expansion of the magnet.
