SOLUTION :
1. Products processing solution
1) customer:
2) product:
3) Processing accuracy: Follow the drawing from customer
4) Work tool&fixture: precise spring collet chuck
5) The technique remarks:
5.1>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.)
6) GONGTIE company will do the best to provide the technique guidance for CNC lathes and related suggestion of the products processing technology.
