We recently delivered a batch of high-precision gear shafts for a major automotive manufacturer in China, demonstrating our capability to meet the automotive industry's strictest standards.
Here is how we solved the two biggest engineering challenges of this project:
- The Machining Challenge (Concentricity):
Operating under high torque, the slender shaft requires flawless alignment. We utilized advanced CNC turning and spline milling to maintain exceptionally tight tolerances across the bearing journals and splines, eliminating high-speed vibration. - The Heat Treatment Challenge (Hard Shell, Tough Core):
The application demands an ultra-wear-resistant surface combined with a shock-absorbing, tough core. Through precisely calibrated induction hardening and tempering, we achieved the exact transition zone and effective case depth required—ensuring maximum surface hardness with zero micro-cracking or geometric distortion.
