technique solution
solution ：
1. products processing solution
1) customer: 2) product: clutch pressure plate； 3） material: fn-0205-25;
4) the product profile
5) machining accuracy: completely follow up the customer’s drawing;
6) work tool and fixture: 6 inch hydraulic 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.)
gongtie company will do the best to provide the technique guidance for cnc lathes and related suggestion of the products processing technology.
8) proposal cnc lathe：
precise linear guide-way cnc lathe with slant base body in t-slot blade row : s36
s36 lathe feature: high precision, high efficiency, heavy cutting, best cost-competitive
*with 45º body base design, and excellent resin sand, die-casting for integral bed body, strict thermal aging treatment, to make sure the high stiffness.
* high precision and sleeve-style independent spindle structure, and high speed hydraulic swing system, to guarantee the high rotating speed.
* high precision and enhanced linear guideway and ballscrew, with central and pre-stretching ballscrew assembly method, for realizing the precise turning with tolerance of µ level.
* reasonable layout, large internal space, fashionable appearance design.
