Mazak SQT250MSY.640T Subspindle transfer

[Zoffen]

I'm trying to do some sub spindle transfer stuff and am looking for a code example to enlighten me on the m codes for spindle syncronizing and turning with both the main and sub supporting the workpeice. Anyone have some code they would like to share?

thanks!

Just I am sure what you asking, you want to turn on the main spindle then grab with the sub spindle and turn with both spindles? Are you handing the part off to sub spindle or using a cut-off tool?

[Jeremy Herron@DBS Solutions™]

Almost forgot to ask, what controller does the machine have?

I want to do it all!!!lol

 

It has a 640T control on it.

 

This is the sequence of events i'm trying to achieve:

 

(Main spindle program)

Open subspindle

Position sub to pickoff position

clamp sub

unchuck main

move sub away from main with the material still being held by the sub

clamp sub

sync spindles

proceed with cutoff operation

(Sub spindle program)

 

basically i'm wondering how to sync both spindles and cutoff while held by both spindles.

 

thanks!

I don't know if this can be useful, but try to program it as you want it in Mazatrol, run the program and check the M and G codes which are used! They are usually shown in the position window on the right side of the "buffer move" and "remaining move", when you run the program! Else take a look on your M and G gode list or contact your local Mazak, they are usually very helpful with info in the cases I have had with correction of post processors etc...

 

HTH....

This is from an Integrex with a Matrix control, but the code should be the same...

 

 

 

(THIS FIRST 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***)

Let me know if you have questions.

 

 

 

 

[Jeremy Herron@DBS Solutions™]

The "M901" stuff may not be necessary on your machine BTW.

Thanks a bunch!

 

Just what i needed.

 

Should be fun to start playing with it next week!
