Tails tock sleeves are used on CNC lathes. It is the equivalent to a tail stock quill on a center lathe but in this case it uses hydraulic pressure to move it in and out of the tail stock.
The function of both tail stock sleeve or quill is to clamp the workpiece by means of a center that is inserted into the sleeve or quill. On a center lathe it is used for drilling also but not on a CNC lathe.

The spindle of a lathe is a rotating hollow tube within, and protruding the head stock and to which a chuck, drive plate or facing plate attaches and rotates to enable machining. It is housed within the head stock in bearings and has some gears around it which is driven by other gears which in turn is driven by an electrical motor.
A milling machine basically look like a drill press, but with the ability to move the work piece sideways. A lathe clamp and spin the work piece horizontally and use a stationary tool bit to cut and shape the work piece.
