Guiding system for machine tools that is held by means of cooling bars

摘要

A guiding system for machine tools of the type having first machine parts with guiding rails fastened thereto and second machine parts supported by shoes on the guiding rails of the first machine parts in such a way that they can be moved with respect to each other. At least in sections along their length that are exposed to high thermal loading, the guiding rails are kept in close pressure contact over a large surface area by cooling bars to which a coolant is applied.

1. A guiding system for a machine tool, the machine tool having a first machine part and a second machine part, the system comprising:
an elongated guiding rail secured to the first machine part, said guiding rail having a base part; a guiding shoe on the second machine part and engaging said guiding rail, said guiding shoe being shaped and configured to be linearly movable along said guiding rail so that the second machine part is movable with respect to the first machine part: at least one elongated cooling bar mounted to the first machine part to maintain pressure on at least a portion of the length of said base part of said guiding rail; and means for applying a coolant to said cooling bar.
