About This Part
The harmonic drive gears processed by our KGL machining are critical in many high-end fields. It is widely used in industrial robot joints, especially the forearms and wrists of collaborative robots, to achieve precise motion control; it is also used in aerospace, such as satellite antenna pointing, space manipulators, precision machine tools, CNC turntables, indexing heads, semiconductor manufacturing equipment, photolithography machines, wafer handling, medical equipment, surgical robots, rotating parts of imaging equipment, optical instruments and high-precision measuring equipment. It is an indispensable core transmission component of modern precision machinery. The core of achieving the excellent performance of harmonic drive gears lies in the perfect combination of material science and precision technology. The key components of our KGL machining are made of special alloy steel with high strength, high toughness and high fatigue limit. As the core elastic deformation element, the flexible wheel needs to be hardened and toughened on the surface through carburizing, carbonitriding combined with precision quenching and tempering processes. The surface teeth are extremely wear-resistant and hard, and the core is strong and tough and fatigue-resistant; its tooth root area also needs to undergo key shot peening treatment to introduce compressive stress to greatly increase fati
