            SOLUTION


      1. Products processing solution


           1) customer: ******


          2) product: 

CNC S36 PLUS BAR FEEDER

 

   


    Processing accuracy: Follow the drawing from customer


CNC S36 PLUS BAR FEEDER



  3) 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.


   7)  Processing flow proposal:
