我厂先进车工朱谈林同志,在参加全国机械工业先进生产者代表会议后,回厂与技术员王兴飞同志共同研究,应用了机械夹固车刀,效果很好。这种车刀在我厂已广泛应用。过去,我厂使用的硬质合金车刀是用黄铜作焊料,用火焰喷嘴(氧炔焰)加热来进行焊接的,焊接的质量差,并且黄铜的熔点比较低。在进行高速切削时,常常出现刀片碎裂及刀片脱落的现象,硬质合金的浪 I advanced car factory workers Comrade Zhu Tanlin, after attending the National Machinery Industry Conference of Advanced Producers, back to the factory and technicians Comrade Wang Xingfei joint study, the application of mechanical clamping lathe, the effect is very good. This type of turning tool has been widely used in our factory. In the past, the cemented carbide turning tool used in our factory was made of brass for welding, which was heated by a flame nozzle (oxy-acetylene flame) for welding. The welding quality was poor, and the melting point of brass was relatively low. In the high-speed cutting, often appear blade fragmentation and blade off the phenomenon of carbide waves
