Hi,

I'm using 2 brand news Hyundai-Kia SKT300MS with Fanuc 21TB controller.
I plan to make work transfer from main spindle to sub spindle while chucks are turning. Does anyones know how to do this with this contoller model. I would like to know if it's only possible with 18T controller or if we can do something.

Thanks !

yes you can do it.
We have a 250 MS with 18-i and a 300MS with a 21-i.

start both spindles up,
Give it a M160. Spindle sync
M162 (Spindle phase sync)
M119 sub unclamp
G0 B-23.5???
M118 Sub clamp
M69 Main unclamp
G0 B0 Sub goes home
M161 cancels spindle sync and spindle phase sync.
etc.
etc.
