对于较大而长的正方体(或长方体)型体毛坯,一般采用弓锯床锯切的方法备料。锯切速度低、耗费原材料比较大。而且对后面工序的加工增加了困难。为此,我们采用在铣床上以铣断的方法进行备料,既可以提高工效,缩短生产周期,又可以节约材料,降低加工费用,而且为后面工序的加工提供了方便。例如,磁性表座的底座体零件,进厂的型材为410×70×50mm,可以加工 For larger and longer cuboid (or cuboid) body blank, bow sawing is generally used to prepare the sawing method. Sawing speed is low, the cost of raw materials is relatively large. But also the processing of the back of the process increased difficulties. To this end, we use the milling machine milling method to prepare, not only can improve work efficiency, shorten the production cycle, but also save material, reduce processing costs, but also for the back of the processing process provides a convenient. For example, the magnetic base seat base parts, into the factory profile 410 × 70 × 50mm, can be processed
