wheel life increased from 25k to > 1MM parts with CBN!
In this application, a customer was grinding the face of a hardened steel valve plate in high-production using a conventional aluminum oxide cup wheel, achieving an average wheel life of 10,000-25,000 parts.
The goal was to increase productivity by increasing wheel life and reducing the downtime for wheel changes. Meister’s solution was to upgrade the process with a vitrified CBN wheel, which improved wheel life dramatically, while maintaining all quality requirements.
Process Summary
Wheels
- original wheel spec: 600-grit aluminum oxide
- NEW wheel spec: 325-mesh Vitrified CBN
Results Achieved
- wheel worked immediately, with all existing feeds / speeds
- wheel wear measured only 0.7mm after 300,000 parts ground
