多刀多刃切削法由去年的偏重用于有色金属,转向了黑色金属;由要求精度较差的工作物转向了精度较高的工作母机部件,并与高速切削快速切削结合起来,由车床进而逐渐扩展到其他各种机床。由于这一先进经验的推广,使机器工业的生产效率与产品质量都大大提高。但有此方面发展还是不够 Multi-blade multi-blade cutting method from last year’s emphasis on non-ferrous metals, turned to ferrous metals; by the poor precision of the work transferred to the higher precision parts of the work machine and rapid cutting combined with high-speed cutting, and thus Gradually expanded to a variety of other machine tools. Due to the promotion of this advanced experience, the production efficiency and product quality of the machine industry have been greatly enhanced. However, there is still insufficient development in this area
