Troubleshooting Guide
Common Issues and Solutions
- Short Working Life: Check grinding wheel grain size - too coarse reduces blade lifespan
- Burred or Dented Edges: Verify cutting edge sharpness and check cardboard moisture content
- Blade Breakage: Ensure proper assembly, avoid improper contact during operation, check grinding wheel bearings
- Chips on Cutting Edge: Inspect grinding wheel stability and prevent hard object strikes
- Uneven Corrugated Board Edges: Match blade strength to high-density corrugated board requirements
