WebSep 15, 2024 · In scan hardening, the inductor or workpiece (or both) can move linearly relative to each other during the hardening cycle [2]. Depending on workflow, the system can be built vertically, horizontally, and at an angle, though vertical-scan hardening is the most popular design for a number of reasons, including a reduced equipment footprint … WebGear Technology magazine, The Journal of Gear Manufacturing : The Gear ...
WebOct 30, 2024 · Case hardening is the process used to prevent brittleness after heat treatment. Case hardening explained. Case hardening produces a hard and wear … Webgear which requires additional finishing operations to correct Gearthe distortions. Dual frequency induction hardening [3] uses a low fre- quency to Thispre-heat the gear and a much higher frequency to very quickly heat the surface of the gear for case hardening. The gear is then immediately quenched resulting in a hard case and good core losses
