Recently, the mechanical properties of ceramic materials were improved, especially their tougthness. The applicationfield of the Si_3N_4-based ceramics as cutting tools has been specified in the high-speed machining of gray cast irons. In paticular, self-reinforced Si_3N_4 with acicular beta-grains and other Si_3N_4-based ceramic tools exhibited high performance under severe cutting conditions.In this note, a trial using ceramic endmill tools made of Si_3N_4-based material has been described. The effect of tool geometry on the cutting performace of the ceramic endmill tool under high-speed cutting conditions was investigated.Results obtained can be summarized as follows.(1) The finished surface of the workpice machined by the ceramic endmill tool was better for a tool with a helix angle.(2) Wear property of the ceramic ball-endmill tool was superior under the high-speed cutting condition (V=1500m/min) to that under the low-speed condition (V=300m/min).(3) The finished surface obtained in high-speed cutting by the ceramic ball-endmill tool was smooth, exhibiting low degree of roughness.(4) The ceramic ball-endmill tool can be successfully applied to high-speed milling of gray cast iron.

近年来，陶瓷材料的力学性能不断提高，尤其是韧性。明确了Si_3N_4基陶瓷作为刀具在灰铸铁高速加工中的应用领域。特别是针状β晶粒自增强Si_3N_4陶瓷刀具和其它Si_3N_4基陶瓷刀具在苛刻的切削条件下表现出很高的性能。研究了高速切削条件下刀具几何形状对陶瓷立铣刀切削性能的影响。(1)对于具有螺旋角的刀具，用陶瓷立铣刀加工的工件表面质量较好。(2)陶瓷球头铣刀在高速（V= 1500 m/min）切削条件下的磨损性能上级低速（V= 300 m/min）切削条件下的磨损性能。(3)用陶瓷球头立铣刀高速切削得到的加工表面光滑，粗糙度低。(4)该陶瓷球头铣刀可成功地应用于灰铸铁的高速铣削加工。
