     6. technical remarks:

          ①  The Program will set up the tools life time management.

              ( the lathe will give out the alarm according to the customer’s preset machining quantities to reduce the products scraps and the tool’s extra                                  damages.)                     

          ②  Add air blowing and water flushing function block on the blade carrier.

          ③  water out of the inner hole of the  Spindle.

8、Preferred  equipment type :D20-H-8C

(1) CNC lathe :precision line guide-way flat bed lathe with double spindles plus blade row D20-H

(2) Loading type: servo robot with gantry loader in tray.

 

9、sketch figure

(1)Here below is the whole sketch figure for the precision line guide-way CNC lathe with double spindles plus blades row. 

         The integral casted rigid structure results in better stiffness of the bed.

2)flow chart of the loading processing :

GONGTIE DOUBLE SPINDLE LATHE FOR HYDRAULIC CHUCK

For this double spindle flat bed lathe, spindle 1 and spindle 2 can move both in the X axial and Z axial direction. The servo robot snatch at the rough part and move to the principal spindle C1 collet ,where the part is served to be turned.

  After finishing the spindle C1 processing, spindle C1and C2 will move to the abutment platform. After their abutment ,the spindle C2 begins the turning while the spindle C1 begins to feed the rough part for the thereafter turning.

         The spindle C2 will move to the abutment platform after finishing the turning. And the robot then snatches back the finished part to the stacking tray Thereafter the spindle C2 waits for the spindle C1 for another working cycle, and so on.
