SOLUTION ：
1. Products processing solution
1) customer: *******
2) product:
3) Work tool & fixture: 6 inch hydraulic chuck
******>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) GONGTIE company will do the best to provide the technique guidance for CNC lathes and related suggestion of the products processing technology.
6) Processing flow proposal:
cycle time and process proposal: 1>ID(rough turning); 2> ID(fine turning); | |||||||
process | tools | Process speed(r/min) | Traverse (mm/r) | Cycle time(S) | |||
ID(rough turning) | | S1500 | F0.09 | ≈3s | |||
ID(fine turning) | | S1800 | F0.08 | ≈5.5s | |||
Processing time | ≈10 | ||||||

total | ≈20 | ||||||
The second process: Precise linear guide-way CNC lathe with flat bed Q7 + gantry auto loader + hoist
8.1> CNC lathe outside total-view sketch:
Technique remarks: the raw parts is stocked by a hoist, first, to position the raw parts at the material staging exit, through the gantry auto loader feeding the raw part to the spindle work fixture, and during the machining time, the auto loader goes to grab new raw part, after finishing the machining, the auto loader take out (unloading) the finished part, meanwhile feed the raw parts to the spindle work fixture, then unloading the finished parts to the convey belt.
The advantages is the machining withe high precision, and more effective running, more stocking quantities, and realize the parts no scratch damages.
