The J.F. Berns Company manufactures high quality CNC Lathe and Bar Feeding accessories to increase your machining productivity. Products include spindle liners, bar chamfering machines, bar supports, spindle stops, draw tubes, draw bars, spindle extensions and special loaders and unloaders.
Spindle Liners (also referred to as filler tubes, reduction tubes, master liners or sleeves), are used to reduce the I.D. of a CNC Lathe spindle. Clearance is application and material dependent, but usually they are sized to 0.030"-0.060" over the diameter of the bar being machined.
The result is faster machining speeds and closer machining tolerances. Spindle liners are used in lathes often in conjunction with bar feeders, bar loaders, baster supports and bar pullers.
