I apologize if this is an inappropriate place to post this question but i really need help. my boss threw a new job at me today and i need to use the tailstock on a hwacheon ht 400 with a fanuc 18-tb control, but i don't know how to get it to unclamp and inject the pin so i can move the thing! if anyone can please explain to me how this works i'd be so greatly appreciative. Also, once i know how to unclamp and inject the pin, it'd be nice to know how to re-clamp the body and retract the pin

Well first you need to know an M code's for your machine. Look in your manual programming book they should tell you. Then include your M codes in the program.

M6 and M7 advance and retract the quill, but the M-code list has nothing about the tail stock body.

For your pin try M31/M32 or M55/M56 or M21/M22. First time you need to align manually. Try with MDI mode,

I know m55/56 are conveyor on/off for that machine but i'll give the other codes a shot. i spent a fair portion of a 12 hour shift today googling and furiously flipping pages in the manual trying to figure this out. quite a frustrating day. thanks for the help
