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: 6” hydraulic 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 toolsdamage.)
8> gongtie company will do the best to provide the technique guidance for cnc lathes and related
suggestion of the products processing technology.
