Is it a fully programmable tailstock?...
I've even made the mistake myself in the past. Is it a fully programmable tailstock or not? what is a fully programmable tailstock?
Often when engineers are new to CNC lathe technology, they overlook what seems to be minor aspects of a lathe purchase, however these minor aspects can prove to be very important.
When looking to buy a new lathe, manufacturers will offer two types of tailstock, a programmable tailstock or a programmable quill, believe me, there's a world of difference between the two.
As per the picture; a programmable tailstock is programmed within the program and is moved using the turret axes as and when required within cycle. There is a lever that extends out of the tailstock (evident in the picture) this is picked up by the turret slide. The benefits to this solution are as the name denotes, it's fully programmable within cycle.
This is different, a programmable quill, is just that. A quill that moves within cycle when programmed, NOT the actual tailstock. You will have to move the tailstock by hand. Moving a tailstock is not that easy, as you have to lock it into place and unlock when you choose to move it. If you do opt for a programmable quill solution, make sure you check the length of the quill's axis, as this will be all the movement you can have within cycle.
