Dedicated manufacturing teams and work cells are established to provide 24-hour delivery of collets and guide bushings for Citizen, Hardinge, Star, Tornos, Traub and Tsugami Lathes - as well as for cam-operated lathes.
Swiss-Type Collets
Hardinge Swiss-type Collets are ground to precise size and TIR to meet precision machining requirements with a standard accuracy that rivals the industry! Every collet and guide bushing is inspected on a Hardinge Super-Precision (.000015" TIR) headstock before reaching the stockroom. Hardinge manufactures to Swiss quality, in the USA, for all brands of Swiss-style machines and cam-operated lathes. Extended-Nose Collets feature added nose length, flat or tapered, for doing pick-off work or to compensate for tooling interference. An Emergency Collet can be machined to the desired bore size. Emergencies are also available in extended-nose for added nose length.
Guide Bushings
Hardinge round Swiss Guide Bushings are carbide-lined to keep the stock clean and unmarked. Specials are available in hardened steel, Meehanite lining, angular & zig-zag slotted and extruded shapes. Escomatic counter collets and guide bushings can be manufactured to order. TSG-20R guide bushings are turned, threaded and bored as shown on this Hardinge QUEST TwinTurn 65 twin-spindle, twin-turret CNC lathe with bar feed. Simultaneous machining is one of the many methods Hardinge uses to increase productivity.
Bar Loader Collets
Hardinge manufactures bar loader collets for FMB, LNS and Robobar bar feeders. Collets available for other brands on request.
Tool and Tap Holders and Collets
Hardinge offers a complete line of toolholders, tap holders, toolholder collets, tap collets and bushings that can be used on Swiss-type lathes. You'll find reliable and economical solutions for back-end, sub-spindle and end-working slides.
Custom ID Pick-off Collets
Custom expanding pick-off collets may be the solution for workpieces with delicate outside threading or a thin wall, and may eliminate the time and cost involved with second operations. A built-in spring ejector can drop each part into a basket or conveyor for automated parts process.
