各种车刀在生产上消耗很大。我厂现在使用的各种车刀大部分是锒焊硬质合金的,刀柄是用45钢锻造出来的。过去,刀柄用自由锻的方法锻出,刀头部分的角度及形状是铣出来的,这样很费工时。近年来,用一套锻模,在60公斤空气锤上锻出车刀柄的主编角、副偏角及后角(即自由锻锤模锻),然后只需铣出锒刀片槽及前角,刨削刀柄底面就行了。节约了大量切削加工工时。现将C620车 Various turning tools consume a lot in production. Most of the lathe tools that I use in our factory now are brazed cemented carbide. The shank is forged out of 45 steel. In the past, the handle was forged by free-forging method, the angle and the shape of the cutter head part were milled out, which took a lot of man-hours. In recent years, with a set of forging die, 60 kg air hammer on the car forging the main editor angle, declination and relief angle (ie, forging hammer forging), and then only need to mound trowel groove and rake , Planing shank bottom on the line. Save a lot of cutting working hours. Now C620 car
