3. Core Manufacturing Processes

1. Precision Fabrication

• Material Selection: The 304 stainless steel housing is forged to achieve a hardness of HV200+, with corrosion resistance superior to conventional alloys. Gold-gold contacts use 99.99% pure gold plating with a thickness ≥5μm.
• Key Technologies:
  • Five-axis CNC machining: Concentricity between ring grooves and bearings controlled within ≤0.01mm
  • Mirror polishing: Contact surface roughness reaches Ra0.02, minimizing friction loss;
  • Vacuum plating: Gold coating on conductive rings ensures uniformity error <1%, stabilizing signal transmission.

2. Integrated Assembly

• Assembled in a fully automated dust-free workshop, using laser positioning to calibrate the gap between brushes and conductive rings (≤0.05mm). The near-zero pressure brush design extends service life by 33%

4. Full-Process Testing System

1. Electrical Performance Testing

• Insulation withstand voltage test: 300VAC power frequency voltage applied for 60 seconds, with leakage current <0.1mA
• Dynamic resistance monitoring: Real-time recording of resistance fluctuations ≤20mΩ at 10,000 rpm

2. Mechanical Reliability Testing

• Life cycle test: Continuous operation at 8,000 rpm for 1,250 hours (equivalent to 10 million rotations), with brush wear <0.1mm
• Environmental adaptability test: 100 cycles in -50℃~80℃ range with no performance degradation

5. Typical Application Scenarios

1. Aerospace Industry

• Aircraft engine testing: Collects strain signals from compressor blades, enabling high-speed data transmission at 18,000 rpm in a turbofan engine test rig

2. Rail Transit
