Solution driven
With our accurate, reliable products and perfect service system, we have won the trust of many users, and gradually built up a good brand impression in the CNC lathes automation industry.
SOLUTION A:
1. Products processing solution
1) customer: *****
2) product: piston rod
3) Processing accuracy: Follow the drawing from customer
4) 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:
turn the two terminal end of the rod , then process the step.
8) recommended lathe:
we prefer to the Q5 lathe for the piston rod whose dimension is not bigger than 20 mm diameter;
when the piston rod dameter is between 20mm and 25 mm we prefer to the lathe Q7.

SOLUTION B:
total sketch of precise linear guideway flat bed cnc lathe Q5 /Q7 with back feeding device
technical remark:
multiple rods can be layed on the feeding device in which each of the rod would be arranged itself as a simple processing method.
After the product is fulfilled ,the receiveing device will stretch out and then finished product will slip into the placing box through the slope groove.
you can save a lot of manual working time so that multiple machines can be looked after due to the stability and reliability of the feeding ,processing and receiving the materials.
