5> Work tool and fixture: 6” hydraulic chuck
6> The technique remarks:
6.1> 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.)
6.2> assembly the air blowing device and water diversion block on the saddling board ( high pressure bump)
7> GONGTIE company will do the best to provide the technique guidance for CNC lathes and related suggestion of the products processing technology.
8> machining accuracy: completely follow up the customer’s drawing;
