PURPOSE:To obtain a shaping material which has excellent dimensional stability, machinability, and polishability, and can be easily cut to give an excellent shaped article, by mixing a cellulose powder with a thermosetting resin binder. CONSTITUTION:A shaping material for cutting is obtained by mixing a cellulose powder (prepared by the acid hydrolysis and mechanical treatment of cellulose or by the mechanical treatment thereof, preferably having such a particle diame ter distribution that the percentage of particles passing through a 100-mesh sieve is 90wt.% or higher and having a moisture content of 10wt.% or less) with a thermosetting resin binder (preferably comprising a liquid epoxy resin and in two pack form consisting of a principal component and a curing agent). This shaping material has excellent dimensional stability, machinability, and polishability, hardly causes wear of a cutting blade in cutting, and shows remark able machinability particularly in high-speed cutting at 10,000rpm or higher. |
