ABSTRACT:
A machine tool having torsional compensation for the machine tool support. Generally, a machine tool head is movably mounted on a cross member in such a way that it induces a torsional couple in the cross member. A mechanism is provided for inducing a torsional couple in the cross member which is substantially opposite to that produced by the supporting of the machine head. In one embodiment this mechanism is a tube which has one end rigidly interconnected with the cross member and another end which is movable relative to the cross member. A torsional force may be induced within the tube by movement of the second end relative to the cross rail and at least a portion of this torsional force is thereby transmitted to the cross member by the rigid interconnection of the first end of the tube with the cross member.
