摘　　要：难加工材料的小孔钻削加工严重地磨损钻头的后刀面,而后刀面的磨损是麻花钻磨损的主要形式。针对难加工材料不锈钢板采用导电加热钻削小孔进行试验,定量地分析了进给量、加热电流以及切削速度等参数与麻花钻后刀面磨损程度之间的关系,并研究了该磨损量对孔壁表面粗糙度的影响趋势。It is very serious of blade wear of twist bit to drill hard-to-cut materials,while the blade wear is the main wear form of twist bit.Aimed at using the electric hot drilling to test hard-to-cut materials as stainless steel plate,the relationship between the grades of the blade wear from parameters such as feeding,heating current and cutting speed to twist drill were analyzed quantitatively. At meanwhile the influence tendency of the blade wear to surface roughness of hole-wall is also researched.
