NT—J320A型数控铣床的Z轴行程为127mm。而我们在该机床上成功地加工了厚度为200mm,两侧表面为圆弧型的大型工件,方法简单易行,现介绍如下。 NT—J320A型数控铣床的主轴孔为30#(7:24)锥孔。而30~#(7:24)锥柄的立铣刀所能加工的最大厚度不超过100mm。加变径套后能装入的立铣刀最大为莫氏3~#柄,也不能加工如此厚的工件。若将立铣刀加长刀杆,则由于刀杆太长,刚度太差,加工时必然产生严重让刀和颤振,精度不能保证,甚至崩刀而无
NT-J320A CNC milling machine’s Z axis travel of 127mm. And we successfully processed in the machine tool thickness of 200mm, both sides of the arc-shaped large-scale workpiece, the method is simple, are described below. NT-J320A CNC milling machine spindle hole 30 # (7:24) tapered bore. And 30 ~ # (7:24) taper shank end mill can process the maximum thickness of not more than 100mm. After the change sleeve can be installed after the milling cutter maximum Mohs 3 ~ # handle, it can not process such a thick workpiece. If the end mill to extend the arbor, then the arbor is too long, the rigidity is too poor, the processing will inevitably produce a serious knife and chatter, the accuracy can not be guaranteed, and even chipping without
