Q7 CNC PLUS ROTARY WORKSTOCKER

TECHNIQUE SOLUTION AS FOLLOWS：

1. Products processing solution

1) customer:； 2) product: NA； 3） material: GJS-500-7,EN-1536 ;

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

5) 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.

6) GONGTIE company will do the best to provide the technique guidance for CNC lathes and related suggestion of the products processing technology.

the processing flow proposal:

the first CNC lathe process--- products fixture method and process proposal(example of H=22.4)

process		tools	Process speed(r/min)		Traverse (mm/r)		Cycle time(S)
flat head, outside chamfer angle			S1600		F0.1		≈9
Inside chamfer angle, turning ID			S1800		F0.1		≈8.5
End face groove			S800		F0.05		≈3.5
Processing time							≈25
Auto loading/unloading + air blowing							≈11
total							≈27
the second CNC lathe process--- products fixture method and process proposal l(example of H=22.4)
fixture from outside internal expansion fixture
process	tools			Process speed(r/min)		Traverse (mm/r)		Cycle time(S)
Flat head, OD processing				S1600		F0.1		≈12
ID chamfer angle				S1800		F0.1		≈2
End face groove				S800		F0.05		≈3.5
Processing time								≈25
Auto loading/unloading + air blowing								≈11
total								≈21.5

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

10.2) Feeding system: rotary workstocker sketch:

Q7 CNC PLUS ROTARY WORKSTOCKER

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.
