摘　　要：对直径为2 mm的高速钢钻头在允许的最大切削速度和进给量条件下,对45钢进行钻孔时的切削温度进行了理论计算和实际测量,得到了钻头前刀面上切削温度值远远低于高速钢耐用度时的温度值,此时钻头磨损的主要形式是机械磨损的结论。The cutting temperature of a high-speed steel drill with diameter 2mm was Calculated and measured under the maximum cutting speed and depth for cutted material of Steel 45. It is qiven that the cutting temperature of drill rake face is far below the temperature of tool life and the main wearing form of drill is mechanical wear.

关 键 词：小直径钻削 切削温度 磨损
