Spindle liners (also referred to as filler tubes, reductions tubes or master liners), are used to reduce the I.D. of a CNC lathe spindle, usually to .030-.060" over the diameter of the bar being machined. The result is faster machining speeds and closer machining tolerances. They are used in lathes often in conjunction with barfeeders, bar loaders and bar pullers.
