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.

Collaboration Process
Engineering Review
Send us your drawings (STEP/IGES/PDF). Our engineers review feasibility, tolerancing, and suggest optimizations for manufacturability (DFM).
Prototyping
We produce small batches for validation testing using soft machining or wire EDM.
Mass Production
Scalable manufacturing with strict batch control.
FAQ
Q: Can you handle gears for high-speed EV motors?
A: Yes. Our capability to achieve ISO Level 5 precision and specialized tooth profile modifications (crowning/relieving) ensures our gears perform quietly and reliably at speeds exceeding 15,000 RPM.
Q: What is the advantage of Gear Skiving over traditional shaping?
A: We use the Kashifuji KPS30 for Power Skiving. It is 3-5 times faster than shaping and allows for "Hard Skiving" (machining after heat treatment), which corrects heat distortion and guarantees superior accuracy for internal gears.
Q: Do you provide heat treatment services?
A: We work with certified partners for Carburizing, Nitriding, and Induction Hardening, ensuring the metallurgical structure meets automotive standards. We control the final hard finishing in-house.
Q: What is your MOQ for custom automotive gears?
A: We are flexible. We can support prototyping (1-5 units) and ramp up to high-volume mass production. Contact our team for a specific quote
