Spindle Liners: 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.

  • Fast Deliveries!!!
  • Guaranteed to Fit: With minimal information, usually just the lathe make & model, we will provide quality spindle liners that are guaranteed to fit your lathe or we will re-work them for free.
  • Easy to order: Minimal information required - usually just lathe make & model
  • Ready to use: Includes mounting holes, screws for attaching to the lathe, adapters if required, and stock size marked on every spindle liner. No drilling is required!
  • Free Extensions: When required to increase lathe bar stock length capacity
  • Experience: The industry leader with 20+ years of experience with a database of over 50,000 spindle liners manufactured.
  • Quality: All liners are manufactured to the highest quality standard.  Each liner is straightened to within .005" TIR
  • Variety of Materials: Steel; Hybrid Style of Steel & Urethane (patent pending); Phenolic; Nylatron & more.
  • Any Stock Shape: Liners can be made for hex, square, irregular shapes, etc.
  • Options: Liners can be honed to special IDs, hardened, lined with non-metal materials and more.
  Quick Change Spindle Liners: With this patented system, a spindle liner can be exchanged in a matter of seconds without tools or loose pieces such as screws or retaining rings.  After inserting the liner through the adapter into the lathe, rotating the liner 30 degrees puts it into the locked position and the spring loaded pull pin keeps liner in place until the next change is made.  The price of quick change spindle liner is the same as our standard liners.  Each CNC Lathe will require the purchase of one quick change adapter.

Spindle liner extensions

Free Spindle Liner Extensions: Extensions are provided when needed at no additional charge.  They increase the bar length capacity of the lathe.  If the extension is longer than the coolant collector, we can also provide coolant collector extensions.
  The FACTS on Metal Spindle Liners
  • They can be made with extensions to increase the lathe spindle capacity
  • The weight of the spindle liner is negligible compared to the capacity of the lathe and does not increase spindle bearing or drive wear - they also do not decrease the maximum turning speed of the lathe.
  • They can be made with extremely thin walls to maximize the capacity of the lathe
  • Less likely than non-metal liners to 'pickup' metal chips that can scratch the part
  • Metal spindle liners can be hardened to 70 rockwell for even less scratching potential
  • Extremely durable
  • Little to no vibration when sized properly
  • We offer the patented Quick Change Spindle Liners for no tool changeovers
  • Because the spindle liner rotates with the stock, metal to metal contact does not create any noise louder than the lathe itself
  • Metal spindle liners are quickly re-workable
  • Specials (such as 2 or 3 part liners) can be designed and manufactured
