1. products processing solution
1) customer:.；
2) product:；
3） material:; ：
4) the product profile
5) machining accuracy: completely follow up the customer’s drawing;
6) work tool and fixture: 6” 3-jaw high speed hollow power chuck
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>installing the additional air-blowing advice on the chuck to make sure no chips on the
surface of the fixture.
8) gongtie company will do the best to provide the technique guidance for cnc lathes and
related suggestion of the products processing technology.

9) proposal cnc lathe：q7-4d
9.1) cnc lathe: precise linear guide-way cnc lathe flat bed : q7
9.2) auto-loading/unloading system: gantry loader with rotary workstocker in 8 station
10)feeding system: rotary workstocker sketch:
remarks: the raw materials will be positioned by the rotary workstocker, and then be moved to the
chuck end face through the gantry loader, then the chuck clamping, and the gantry loader move to
the feeding area(above of the 8 station rotary workstocker，start the processing. after the products
be finished, the gantry loader take out the processed products and move to the rotary workerstocker.
taking example of h=22.4, the rotary workstocker can stock around 100pcs products. this cnc
machine has the features of stock more, faster feeding and better processing precision.
