Under the action of alternating load and impact load, the gear surface is subjected to higher stress than the core under the action of the gear. In the case of friction, the surface layer of the gear is also constantly worn, so its surface layer needs high strength, high hardness and high wear resistance. Surface induction quenching by induction hardening equipment can meet the above requirements.
Double station quenching machine can realize induction quenching of two gears at the same time to improve the quenching efficiency. And the quenching effect of both gears is very good. Two gears are placed on the machine tool and are simultaneously heated and spray-cooled. The entire quenching process is fully automatic, and the operator can set the heating time and cooling time in advance.
Double station quenching requires induction hardening equipment and CNC quenching machine tool to complete the process to ensure high precision machining. After quenching, the strength, hardness and wear resistance are significantly enhanced. Because the induction quenching has the advantages of small deformation and high productivity, it is widely used in production.
