Process type: Carburizing and quenching + tempering / Other surface hardening processes (selected according to product requirements).
Equipment and Control: Utilizing multi-zone temperature control for multi-purpose furnaces and strict management of the quenching medium, it achieves uniform carburized layers and controllable quenching hardness.
Indicators and Quality Assurance: The surface hardness, carburizing depth, core toughness, etc. have all undergone hardness testing and metallographic inspection before leaving the factory, ensuring the wear resistance of the tooth surface and the fatigue resistance of the tooth root.
Advantage description: The highly stable heat treatment significantly enhances the wear resistance and fatigue life of the gears, which is a crucial factor for the long-term reliable operation of large and heavy-duty reducers.

The processing procedure includes rough casting finishing, CNC rough and fine milling, mirror milling / fine boring in combination, assembly positioning hole processing, etc.
Key points: High rigidity machine tools and fixture design ensure the flatness, coaxiality and installation matching accuracy of the box body, thereby reducing assembly stress and improving the stability of the entire machine operation.
Surface treatment: Combining lost foam casting with fine processing to improve the surface finish and dimensional consistency of the box body, making the product both "perform well" and "look good".

Before and after assembly, each rotating component undergoes rotor dynamic balance testing and noise vibration analysis.
By optimizing tooth profile trimming, fit clearance and lubrication design, noise is suppressed at the source and transmission efficiency is improved.
Result: Ensure no abnormal vibration or noise during the operation of the entire machine, and adapt to applications that are sensitive to noise (such as wind power, precision manufacturing, etc.).

Assembly is carried out in accordance with standard operating procedures (SOP) and torque/gap control; strict sealing and leak prevention measures are adopted at key joints.
The component management and assembly traceability system ensures that the source of parts and the assembly process of each product can be traced.
