Machinery Processing

Manufacturing Process Flow:

Forging/Casting – Precision forging or sand casting to ensure material density.
Rough Machining – Turning/milling for preliminary shaping.
Heat Treatment – Carburizing & quenching + tempering to enhance surface hardness and core toughness.
Finish Machining – CNC gear hobbing/grinding for tooth profile accuracy.
Deburring & Polishing – Minimize frictional losses.
Dynamic Balance Test – High-speed operation stability.
Quality Inspection – Gear testing center (profile, helix, hardness verification).

Grinding Process Overview

No Undercut Design: The left and right helical teeth intersect at the center, requiring specialized grinding strategies.
High-Precision Requirements: Typically conforms to DIN 3962 Grade 3 or AGMA Class 13 accuracy standards.
Tooth Flank Twist Control: Strict management of tooth alignment deviation to prevent meshing interference.
