This paper describes some cutting performances of diamond plated wire tools. 2 types of wire tools of 0.22mm in outer diameter with different diamond grain size have been used. They are l0μm grain and 35μm grain. Ceramic materials and silicone rubber are selected as difficult-to-machine materials. These wire tools are moved with reciprocating motion and their cutting performances are estimated by their accumulative cut area with the number of cycles. Also the changes of the tool and the grain are studied by SEM. Results obtained are as follows : it is hard to cut a silicon nitride ceramics comparing with alumina ceramics on account of the hard wear of the diamond grain; the cutting rate sensitively depends on the cutting load. Wire tool can cut silicone rubber as well as alumina ceramics.
