Frequently Asked Questions
Q: Can older crankshafts with severe scoring be salvaged?
A: Yes—our multi-pass grinding protocol removes up to 3mm of material while preserving heat-treated layers. Post-grinding hardness testing ensures compliance with OEM standards.
Q: What training/support is provided?
A: Includes on-site installation supervision plus a comprehensive operator certification program (16 hours). Remote troubleshooting via augmented reality (AR) guides is available.
*Q: How does this compare to outsourcing repairs?**
A: In-house grinding cuts turnaround from weeks to days—with no transport risks or vendor markups. Cost savings average 45–60% per shaft after Year 1.*
