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.)
5.2>Installing the additional air-blowing advice on the collet to make sure no chips on the surface of the fixture.
5.3>Installing the additional air-blowing advice on the tool holders.
6) GONGTIE company will do the best to provide the technique guidance for CNC lathes and related suggestion of the products processing technology.
