Aerospace and High-End Power Sectors
Core Requirements:Gear precision must meet ISO grades 3–6; precision gear grinding processes are employed.
Application Scenarios: Aircraft engines and high-speed turbomachinery. These require absolute reliability under conditions of high temperature and high rotational speeds (up to 71,000 rpm); any deviation in precision could lead to serious safety incidents.
Precision Machine Tools and Measuring Instruments
Core Requirements: Gear precision must meet ISO grades 2–7; gears in certain indexing mechanisms require nanometer-level surface roughness.
Application Scenarios: Spindle drives and indexing mechanisms for precision machine tools, as well as various high-precision measuring instruments. Gear precision directly determines the machining or measurement accuracy of the entire machine, and backlash (return error) must be kept to an extremely low level.
Industrial and Humanoid Robotics
Core Requirements: Gear precision must meet ISO grades 3–6; strict requirements exist for lightweight design and high-ratio synchronous transmission.
Application Scenarios: Robot joint reducers (such as harmonic drives and RV reducers). These ensure precise control of robotic movements and represent the fastest-growing segment of the high-precision gear market.
