PCT No. PCT/EP86/00259 Sec. 371 Date Jan. 5, 1987 Sec. 102(e) Date Jan. 5, 1987 PCT Filed May 2, 1986 PCT Pub. No. WO86/06666 PCT Pub. Date Nov. 20, 1986.The present invention relates to a guidance system on a machine, especially a machine tool, consisting of a twist-resistant, vibratioin damping support body, of concrete for example, and at least one body fastened thereon or integrated therein, which is not of itself twist-resistant, and which forms the guidance ways. In order to endow such guidance ways with minimal thermal expansion and elasticity, make them very hard, give them good low-lubrication running characteristics, and enable them to be manufactured simply and very accurately, the body forming the guidance ways consists of sinterable nonmetals, especially ceramic material.
