precision cnc lathe q7 4a-1929cc威尼斯

technique solution

1. products processing solution

1) customer:

2) product:

3) processing accuracy: follow the drawing from customer

4) work tool&fixture: 6 inch hydraulic 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.)

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:

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
auto loading/unloading				≈10
total				≈20

8) proposal equipment：

the second process: precise linear guide-way cnc lathe with

flat bed q7 gantry autoloader 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.
