Can anybody throw any light on parting off on Nakamura TW20 using parts catcher on sub spindle. Any help would be appreciated.

I have an old program from a TW20 that has a cutoff op in it. But I'm not sure what you want. Do you want me to type up the relevant parts with the wait codes?

Hi extanker59

Any help at all would be appreciated. At the moment we are unsure how to get the sub-spindle across and the catcher in position to catch the part.

Hi
Have you tried sub-spindle transfer on a nakamura tome tw20
if so, could you please share the codes and procedure
i have tw20 1989 model with fanuc 0tc control
any help or pointers on this please
regards
Hemanth

[stjohn_goldfingle]

I will add something to this post. Fusion360 has a post processor - nakamura tome fanuc that works with the tw10 etc very well on the main spindle. It does not work on the sub. I am looking at this now...

cheers!
