Yes you would need a relay, but surely if you are going to actually use this
machine, would not somebody be operating its other functions, you need an NC
machine to be able to do all the adjustments remotely. I cannot think of any
reason for doing this unless you are machining something radioactive or
toxic like beryllium or plutonium!

Whoops

This is what I was referring to

As the others said, it won't control a three phase load directly since its
intended as a light switch it will be only switching one pole, and you
need three or four (depending on if your three phase machine has a neutral
or not), and also it will have very limited current switching capability
(and that might be even more limited when switching inductive loads like
motors).

You could use it to remotely switch a three phase contactor or possibly
even a variable frequency drive.
