Rotary indexer takes heavier loads
Robust rotary indexer takes heavier radial and axial loads and offers greater accuracy and more spindle clearance and tooling access.
The Hardinge 5C2 Rotary Indexer offers more accuracy, more spindle clearance, more axial load and more radial load when compared with its earlier 5C models Hardinge has streamlined the indexer body to a curved front casting over the spindle and has made the handle removable for increased spindle clearance and tool access

Added performance and capability at no extra cost on all of the Hardinge produced VMC II range, which have been enhanced with new spindle drives and motors and still start at GBP32,000.
Hardinge speeds up pick-up spindle VTL working
The revolutionary Hardinge / EMAG joint venture produced VL machines provide a guaranteed load / unload time of 4 - 6 seconds - chip to chip - which is critical for cycles of 30 sec and less.
The robust, dual-bearing spindle accommodates heavier radial and axial loads increasing overall indexing capabilities.
100 lb (50kg) part weight and 1000 lbf (4448N) tailstock thrust per spindle is not a problem, said the company - even on a quad unit with tailstocks.
* Design features - a hardened and ground steel worm gear with cross-axis helical gears and a hardened and ground steel worm drive shaft provide high accuracy and reduced wear.

Bar and chucking lathes designed for hard turning
Designed for hard turning use, CNC bar and chucking lathes lift the performance / price index by as much as 30%, in terms of productivity on a very wide range of applications.
Double eccentrics provide the finest gear mesh adjustment.
Hardinge has lowered the backlash range and improved accuracy overall.
The customer can perform future gear wear compensation for extended life and improved accuracy over time.
The Hardinge 5C2 unit has +/-4 arc.sec repeatability, +/-25 arc.sec accuracy and a maximum run-out of 0.0002in (0.005mm) TIR (total indicated run-out).
Each unit shipped contains a printout of accuracy - final inspection is performed using a Heidenhain encoder mounted directly on the spindle nose to assure final positioning accuracy and repeatability.
Hardinge offers three collet closer options to best suit the shop requirement.
The pneumatic fail-safe closer provides 1760 lbf (798kgf) of drawbar force and features a 27mm through-hole.
The pneumatic high-force closer allows reduction of gripping force for delicate parts.
The manual closer is lever-operated with 950 lbf (431kgf) of drawbar force.
Hardinge told manufacturingtalk.com that it is easy to integrate the 5C2 Rotary Indexer into an existing CNC manufacturing application for true 4th axis interpolation.
The Hardinge system is compatible with Fanuc, Siemens, Heidenhain, Hurco, Milltronics, Fadal, Haas Yaskawa and other CNC systems.
The 5C2 is industry compatible for drop-in replacement with fast 360 deg/s indexing speed.
The Hardinge design incorporates a collet-ready spindle for total gripping flexibility.
Collets, step chucks, expanding collets and manual jaw chucks can be used without the use of an adapter.
This allows a wide variety of gripping options to handle most part sizes, shapes and materials.
* History of the 5C rotary system - the evolution of the Hardinge 5C rotary system began in 1901 with the production of Hardinge's first 5C collet.
Hardinge introduced the 5C 'threaded-nose' spindle in 1940 on a precision bench lathe.
In the 1960s Hardinge manufactured a 5C manual indexer using their threaded-nose spindle and collet closer design.
Later the Hardinge 5C rotary system was manufactured based on their original 1960s mechanical design.
Today, Hardinge takes the 5C indexing market to the next level with more accuracy, more spindle clearance, more axial load and more radial load with its 5C2 Rotary Indexer.
