CNC Machining High Precision Hardening Heat Treatment Gears

Induction hardening is commonly used in the heat treatment of gears. Induction heating is a process which uses alternating current to heat the surface of a gear tooth. The area is then quenched resulting in an increase in hardness in the heated area. It is typically accomplished in a relatively short period of time.

Different heat treating processes’ as well as the materials being treated, impart particular qualities. Heat treatment is a critical and complex element in the manufacturing of gears that greatly impacts how each will perform in transmitting power or carrying motion to other components in an assembly. Heat treatments optimize the performance and extend the life of gears in service by altering their chemical, metallurgical, and physical properties. These properties are determined by considering the gear’s geometry, power transmission requirements, stresses at different points within a gear under load, load cycling rates, material type, mating part designs, and other operating conditions.

Guangda Core advantage for the precision gears

• Listed company. Strong scientific research ability , Strength for Market experience and customer service .
• Completed industrial supply chain for smelting, casting ,forging, heat treatment to the precision finished processing.
• Better control for the cost ,quality,delivery term as we control every link of the completed chain.
• Certificate PED,DNV, BV, Rina, ISO, GL, ABS, LR etc.

Comparing with companies who only make the material , we directly face the end customers and better understand customer's demand. Compared with comapanies who only do the processing, we can accurately control the quality of materials to meet the technical requirements of customers. In this way we could provide a holistic solution and control the cost of the whole process, meet the delivery time, and resist market risks.
