Klingelnberg Gears to the equivalent of AGMA quality 13 Surface hardness of 58-63 Rockwell C or higher Exceptionally smooth and quiet operation Up to 30% increased load carrying capacity Capable of pitchline velocities in excess of 20,000 ft./min. True Spiral tooth geometry up to 85" diameter.

 

Gleason Bevels up to 100" DIA

Full capabilities for cutting, hardening, and testing Conventional Gleason, straight, and skewed tooth bevels Hypoid, Zero®, and Coniflex® gear designs Gleason Gears to AGMA quality 10

Carburizing Furnace Systems Two new state of the art vertical pit furnaces.

Employ the latest U.S. and European technologies Accept work pieces up to 80" in diameter and 100" long Have four controlled heating zones to ensure consistent and uniform results Continuously monitor the entire carburizing process Can display the actual carburizing profile via carbon content in real-time Have rapid cooling systems that cool both the retort and workload

84" Quench Press Our new 84" diameter Quench Press is possibly the largest in the world.

Custom designed and manufactured Hydraulic cylinder applies pressure to clamp the gear flat while the expander ram applies hydraulic pressure to hold the gear concentric Minimizes distortion during the hardening process Gives hardened gears more uniform stock removal during post heat machining
