In September 2025. an innovative fixture technology for automotive wheel hub grinding was authorized by the National Intellectual Property Administration. This fixture enables multi-angle free rotation of wheel hubs through an adjustable rotating shaft structure and modular clamping units, addressing industry challenges related to inadequate coverage of complex surfaces with traditional fixtures.

Its core technology lies in the high-precision bearing linkage system, which allows 360-degree rotating grinding without stopping the machine, significantly reducing processing downtime. Test data show that this technology improves wheel hub polishing efficiency by approximately 30% and reduces surface scratches caused by repeated clamping.
