Industry Pain Points and Requirements Analysis
Current medical robotics industry faces six core challenges: 1) Extremely high repetitive positioning accuracy requirements (within ±0.1mm); 2) Long-term operation in sterile environments, requiring higher standards of cleanliness and corrosion resistance; 3) Compact structural design due to space-constrained operating room layouts; 4) Stability under temperature-sensitive conditions (stable output required at various temperatures); 5) Low backlash for multi-degree-of-freedom coordinated control; 6) High reliability assurance for human-robot collaboration safety.
Waimica Customized Solutions

Typical Application Case
A German orthopedic surgical robot manufacturer selected Waimica’s customized RV-80N gearbox for its MRS-7 project, successfully enabling sub-millimeter precision cutting for knee replacement surgery. Key configuration parameters include:
- Reduction Ratio: 80:1
- Output Torque: 350N·m
- Dimensions: Φ80×115mm
- Material: 7075-T6 aerospace-grade aluminum alloy (anodized treatment)
- Operating Temperature: -10°C~150°C
- Protection Rating: IP67
- Mounting Method: Flange embedded + dual locking screws
This solution reduced mechanical arm end trajectory deviation from ±0.3mm to ±0.07mm through optimized gear meshing angles and dynamic compensation algorithms, improving surgical success rate by more than 15%. After 1,000 continuous hours of simulated surgery testing, the mean time between failures (MTBF) exceeded 20,000 hours, far surpassing industry standards.
