Large size commercial gears are high load items that are often accompanied by problems such as inconsistent hardening and distortion.
Fuji Denshi's circumferential single-shot hardening system heats the entire perimeter of the gear with high power in one step which results in even heating. After heating, the work piece is submerged and quenched by dip-spray to achieve an even hardened, high strength, high toughness and high precision result.
