technique solution
solution ：
1. products processing solution(refer to drawing 378y2)
1) customer: 2) product: 378y2； 3） material: ;
4) the product profile
5) machining accuracy: completely follow up the customer’s drawing;
6) work tool and fixture: 6.1) precision customized 6 inch power chuck
6.2) double quill clamping
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.)
8) gongtie company will do the best to provide the technique guidance for cnc lathes and related suggestion of the products processing technology.
