Spindle Liners Vibration Dampening for C.N.C. Lathes

Spindle Liners - Anti Vibration


Pro-active Technical Solutions Ltd are delighted to be working with another great innovator of CNC lathe accesories bringing our customers across the UK more opportunities to save time and money.

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

Since 2003,Trusty-Cook have held the U.S. patent 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 their plant and is designed to solve application issues, extend the life of tooling and machine spindles and plain and simply put, allow your machine to produce better component parts.

The liners are manufactured from an engineered polyurethane. The technology behind the manufacturing allows for not only holding round, square and hexagonal stock but also extruded shapes can be held securely within any machine drawtube.

We have an extensive database of machine drawtubes, a sample of these manufacturers are shown below.
