Hardinge Rotary ProductsMore Accuracy, Speed and Flexibility!The Most Flexible Quick-Change Workholding Concept in the Market Hardinge’s A2-4 (5C) and A2-5 (16C) spindle nose designs allow quick change between collets, expandingcollets, step chucks, 3-jaw chucks and face plates. Common spindle tooling can be shared between theHardinge Rotary System(s) and a lathe. The gripping is in the spindle, closest to the spindle bearings, unlikesurface-mounted adapters used on traditional rotary tables. Multiple workholding options provide alternategripping solutions for increased precision and capability.800.843.8801 www.ShopHardinge.comwww.HardingeWorkholding.com2

Quality Manufacturing ProcessesHardinge's GD5C2 has higher accuracy, more spindle clearance and more thrust and radial load.All rotary products are manufactured in Elmira, New York to strict specifications.Curved front casting and removablehandle for increased spindleclearance and better tool access.Robust, dual-bearing spindle forheavier radial and axial loads.50-lb (23kg) part weight and 1000-lb(4448N) tailstock thrust per spindle isnot a problem – even on a quad unitwith tailstocks!14 5 arc-sec Repeatability 30 arc-sec Accuracy.0002" Max. Runout (.005mm TIR)62543Hardinge next-generation 5C2 mechanically outmaneuvers the competition.1. HOUSINGMachined and bored on a Dixi 280 precision CNC jigboring machine for close tolerance finish dimensions.Foundry castings (made in the USA) provide vibrationdamping.2. SPINDLESpindle is finish ground on a high-precisionKellenberger CNC universal grinding machine. Allsurfaces where bearings and gears are installed areground in the same setup for maximum accuracy.3. BEARINGSHigh-load, tapered dual roller bearings are used tosupport heavy radial and axial loads and to provide alonger spindle life.THE EVOLUTIONOF THE HARDINGE 5C2INDEXER SYSTEM44. DOUBLE ECCENTRICSDouble eccentrics (not single) provide the finest gearmesh adjustment. Hardinge has lowered the backlashrange and improved accuracy overall. Customers canperform future gear wear compensation for extended lifeand improved accuracy over time.5. WORM DRIVE SHAFTHardened and ground steel worm drive shaft is standard.The process begins on a Hardinge SUPER-PRECISION CNC lathe and the threads are finish ground on a Drakethread grinder. Grind quality of AGMA class 13 is verifiedon a Wenzel CNC gear inspection machine.INSPECTIONFinal inspection of every unit is performed using aHeidenhain encoder mounted directly on the spindlenose to assure final positioning accuracy and repeatability.Printout of accuracy is shipped with each unit.19011940Hardingemanufactures the5C ColletHardingemanufactures andintroduces the 5C"threaded-nose" spindle6.
