About Automotive Gears
Detailed Product Features
Superior Noise Reduction
Building on our experience manufacturing zero-backlash harmonic drives ( 10 arc sec), we apply the same rigorous standards to automotive gears. Our ISO Level 5 precision ensures smooth meshing, significantly reducing whine and vibration in Electric Vehicle (EV) reducers and high-speed transmissions.
Complex Internal Gear Capability
Equipped with the state-of-the-art Kashifuji Gear Skiving Machine KPS30, we specialize in manufacturing high-precision internal ring gears used in planetary gear sets (Automatic Transmissions & Hybrids). This allows for integrated gear manufacturing that traditional hobbing cannot achieve.
Ultra-Precision Surface Finishing
Our capability extends beyond shaping. With ultra-mirror finishing capabilities (Accuracy 0.002mm), we optimize the gear surface to reduce friction, extend service life, and improve overall transmission efficiency.
