Wire electrical discharge machining of pressureless sintered TiB2 containing Cr and C as the sintering aids was investigated. The effects of machining conditions on the surface roughness and bending strength were discussed. The surface roughness increased with increase in the cutting speed. The bending strength remained with increase in the cutting speed to 5-40mm2/min. The bending strength of 320MPa was very close to the values for sintered body prepared by cut and polished with a diamond disc and powder.
