SOLUTION


1. Products processing solution(refer to drawing 026 71 440 with logo of 6976)


   1) customer: *****   


   2) product:  CRANKSHAFT 


   3) material: SPHEROIDAL GRAPHITE IRON;   




   4) the product profile



S350 CNC FOR CRANE SHAFT PROCESSING


  5) machining accuracy: completely follow up the customer’s drawing;


    6) Work tool and fixture: precision customized 6 inch Power Chuck


    7) The technique remarks: 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.)


    8) During the designing of the fixture, soft jaws should keep away from the tools, so we choose the CNC lathes with T-slot blade row for reducing the machining cycle time.( can choose the V-8 servo turret if the customer request)


    9) GONGTIE compan the best to provide the technique guidance for CNC lathes and related suggestion of the products processing technology.y will do
