work tool&fixture |
machining process |
time |
xxx |
spring collet |
machining end face, drilling hole, side face drilling hole |
≈22s |
loading&unloading process:servo robot for short&small work piece |
≈8s |
||
total: |
≈30s |
5) machining accuracy: completely follow up the customer’s drawing;
6) work tool and fixture: precision spring collet
7) the technique remarks:
7.1) 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.)
7.2) the spindle with brake device
7.3) figure with the end face & side face head spindle
8) gongtie company will do the best to provide the technique guidance for cnc lathes and
related suggestion
of the products processing technology.
