technique solution
1. products processing solution
1、customer:
2、product:
3、material
4、the product profile
5、machining accuracy: completely follow up the customer’s drawing
6、work tool and fixture: homemade external chuck
7、the technique remarks: the program will set up the tools life-time management (customer pre-set up the q’ty of the machining products, when reach it, automatically warning, for reducing the products scraps and the tools damage.)
collet and blowing device.
the first processing technology route:
③ rough turning step, flat head, outer diameter ② flat head fine turning step
③chamfer drilling with compound drill ④tapping
