1. Introduction: Precision Starts with "Heat"In gear manufacturing, heat treatment is a core process that determines the gear's strength, hardness, and fatigue life. However, it also brings a major challenge for manufacturers—deformation. After carburizing and quenching, gears often experience issue

Core ConclusionIntermediate inspection during rough hobbing is crucial for ensuring gear machining quality, which can promptly detect deviations and reduce scrap rates. Two key inspection points (chordal tooth thickness and common normal length) are essential to control groove width, pitch, and toot

As the core component of machine tools, the machine tool spindle bears complex loads and has extremely high precision requirements. Its machining process directly determines the machining accuracy and stability of the machine tool. Based on the example of a CNC boring machine spindle, this article s

Gear tooth profile modification is a core precision optimization technology in mechanical transmission engineering. It involves deliberate, micro-scale adjustments to the geometric shape of gear teeth—departing from the ideal involute profile—to address inherent challenges in gear operation. This te
