Abstract
A structural member for a machine tool is formed of a nonmetallic substance, e.g. cement, concrete cement or ceramic, having discrete solid objects, e.g. fibers, filaments, chips, fragments and/or particles, of a metal, carbon, ceramic, cermet and/or plastic dispersively distributed therein as reinforcing elements. Metallic frames may be embedded in the nonmetallic substrate to form a skeleton for the member.
Claims8
A method of making a structural member for a machine tool which comprises the steps of:
- (a) dispersing in a mass of a hardenable nonmetallic substance, a multiplicity of discrete solid objects forming reinforcing elements and in an amount comprising 0.5 to 30% by weight of the resulting composition;
- (b) shaping said composition into a configuration corresponding to the shape of the structural member and including at least a machine tool bed and a machine tool column extending upwardly from said bed;
- and
- (c) hardening the mass of the shaped composition to form the structural member as a rigid body with said elements distributed throughout said column and bed.
A machine tool support member comprising a bed, a column rising from said bed, and a head extending from said column and overlying said bed, said head, column and bed being formed unitarily from a hardened mass of nonmetallic material selected from the group which consists of cement, ceramic and concrete containing dispersed and embedded therein, 0.5 to 15% by weight of discrete solid objects selected from the group which consists of metals, carbon, ceramics, cermets and plastics and reinforcing said mass without rendering the same significantly thermally or electrically conductive thereto.
