Project Overview
This project involved manufacturing high-precision engine shafts for a performance automotive client. The parts required exceptional durability to withstand high RPMs and strict concentricity to prevent vibration.
Challenge
The main challenge was maintaining concentricity across the 600mm length while achieving a mirror-like surface finish on the bearing journals. Any deformation during the hardening process would render the part unusable.
Our Solution
We utilized our 4-axis CNC turning center with live tooling for primary machining. To address the deformation issue, we applied induction hardening followed by precision cylindrical grinding. This ensured the core remained tough while the surface achieved the required hardness.
Results
- 100% pass rate on dynamic balancing tests
- Achieved Ra 0.4µm surface roughness consistently
- Delivered 2 days ahead of schedule
- Client reported a 15% increase in engine lifespan
