激光器再配上CNC(计算机数控)系统,用来切割复杂齿形的锯片,不仅方便、快速,而且可获得很高的经济效益。这种工艺具有很多优点:(1)调整时间短,过去切割齿形需要六道工序并动用两台机床(铣床和冲床),现在只需在激光切割机上按揪扭和装料、卸料就可以了,并且对加工的几何形状几乎没有什么限制;(2)每一张锯片的生产工时平均减少67多;(3)工、模具费用的节省是十分可观的;(4)可以生产出特殊形状的锯片。总之,这一新工艺把一种劳动密集型的操作变成技术密集型的操作。据估计,全部投资四年便可回收。
Coupled with the laser CNC (computer numerical control) system, used to cut complex tooth-shaped saw blades, not only convenient, fast, and can get very high economic benefits. This kind of craft has many advantages: (1) The adjustment time is short, in the past the cutting tooth form needs six processes and uses two machines (milling machine and punch press), now only needs to press the pulling twist and the loading in the laser cutting machine, unloading can , And almost no restrictions on the machining geometry; (2) the average number of man-hours reduced by more than 67 per blade; (3) savings in labor and die costs are considerable; (4) special shapes Saw blade. In short, this new process turns a labor-intensive operation into a technology-intensive operation. It is estimated that all investment will be recovered in four years.
