What Makes Us Different

To call the polyurethane spindle liner revolutionary might sound exaggerated to those who are unfamiliar with bar turning technology — but Trusty-Cook’s patented CNC lathe accessory allows machinists to manufacture parts from extruded profiles and odd shapes to the same exacting tolerances as parts machined from standard round stock.

Since 2003, we’ve held U.S. patent number 6,634,263 B2 for inventing the first tubular, one-piece, unibody spindle liner with an outside and inside diameter that may be sized to fit virtually any spindle of a turning machine.

Every spindle liner is manufactured in our plant and is designed to solve application issues, extend the life of tooling, and, plain and simply put, allow your machine to crank out good parts, as our customers will tell you:

WOW!!! That spindle liner is awesome. We have had vibration issues for years on this machine. Steel liners only carry the vibration through the spindle, through the collet and right to the surface finish of the part. This liner totally eliminated it. We will be doing more business real soon. Thanks!
