Spindle Transfer

[KCollins]

When all else fails ask google....when that fails ask the forum.

 

We have a Mazak dual turn (twin spindle lathe) that has been converted over to run eia/iso. I'd like to set up the spindle transfer to auto load parts from one chuck to the other but I dont have a roadmap of the GCode required. Does anyone have any experience with a similar lathe? Any help would be greatly appreciated.

This is a cut-off transfer from a newer mazak but should give you a starting point. Let me know if you need more explanation on anything...

 

(THIS FIRST PART IS JUST SO I CAN USE THE MAZATROL SET UP INFO PAGE)

 

#997=5.46894 (***HEAD 1 Z OFFSET***)

#998=-55. (***PICKOFF POS - MANUALLY BRING SUB-SPIDLE OVER ON FIRST PART TO WHERE YO WANT TO GRAB PART AND THIS A MACHINE POSITION***)

#999=[[#997]+[ABS[#998]]] (***HEAD 2 OFFSET - THIS KEEPS MY PART ZERO THE SAME SO I NEVER MOVE MY PART IN MASTERCAM***)

#990=6.199 (***W-AXIS PULL AMOUNT - THIS HOW MUCH YOU WANT TO PULL OUT THE PART ***)

#996=[[#997]+[#990]](***SYCHED OFFSET - THIS KEEPS MY PART ZERO THE SAME SO I NEVER MOVE MY PART IN MASTERCAM***)

Thanks for the reply. Is this supposed to append to the first part program or does it go in as a separate program? This isn't something I'm familiar with and the only person here whos done it in the past used Mazatrol 15+ years ago to accomplish it.

The part before (TRANS-CHUCK) goes at the head of the program, the part after (TRANS-CHUCK) goes wherever you want the transfer to occur, if you pm I will send you the entire .eia file fo reference.
