在参观北京展览会后,我厂为了不断地降低刀具制造成本,大胆试验了铸造硬质合金车刀来代替焊接式车刀。对铸造车刀经多次反复的试验,目前已取得良好效果,并已应用到生产中去。实践证明:铸造车刀在正常的、稳定的切削负荷下,所允许的切削用量和刀片刀杆的粘结牢固程度,都不次于整体焊接式车刀。图1是我厂铸造的90°外圆车刀。图2是铸造示 After visiting the Beijing Exhibition, I plant in order to continuously reduce tool manufacturing costs, boldly tested the casting of carbide lathe instead of welding-type turning. The casting tool after repeated tests, has achieved good results, and has been applied to the production. Practice has proved that: Casting tool in the normal, stable cutting load, the allowable cutting amount and the blade blade bonding firmness, are not inferior to the overall welding type turning tool. Figure 1 is my factory casting 90 ° cylindrical lathe. Figure 2 shows the casting
