ABSTRACT:
A machine tool elevating and guiding apparatus comprising a tool mounting head which is movable vertically between a pair of guide columns. Guide surfaces on the guide columns are positioned closely adjacent to guided surfaces on the tool mounting head and a flow of pressurized fluid is passed at a fixed pressure between the guide and guided surfaces, such as to eliminate tilting of the tool mounting head. At least one guide surface serves as a reference surface, with a thin film of pressurized lubricating oil being formed between this and an adacent guided surface. The tool mounting head is mounted on an elevating feed screw, with means provided whereby the weight of the head is supported independently of that screw, so that a very high degree of precision in vertical positioning of the tool mounting head is attained.
