Rotary Indexer

Hardinge has streamlined their indexer to a curved front casting over the spindle and has made the handle removable for increased spindle clearance and tool access. The dual-bearing spindle accommodates heavier radial and axial loads increasing overall indexing capabilities. Having 100-lb part weight and 1,000-lb tailstock thrust per spindle is not a problem, even on a quad unit with tailstocks.

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. 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 5C(2) unit takes the field with a ± 4 arcsecond accuracy and a maximum runout of 0.0002" TIR.

Hardinge offers three collet closer options to best suit the shop requirement. The pneumatic fail-safe closer provides 1,760 lbs of drawbar force and features a 27-mm through-hole. The pneumatic high-force closer allows reduction of gripping force for delicate parts. The manual closer is lever-operated with 950 lbs of drawbar force.
