Ledger Mechanism — The Heart of Your Tobacco Cutter
The ledger mechanism in Hauni KTC and KTH tobacco cutters positions the cutting blade against the anvil with micron-level precision. Proper maintenance is essential for consistent cut quality.
Daily Checks
- Verify blade-to-anvil clearance (should be 0.02-0.05mm)
- Listen for unusual grinding or knocking sounds
- Check cutting pressure readings on the machine display
- Inspect cut tobacco for width variation
Weekly Maintenance
- Clean ledger mechanism surfaces with compressed air
- Check all mounting bolts for proper torque
- Inspect blade edge condition under magnification
- Verify pressure gauge calibration
Monthly Service
- Remove blade and inspect the ledger assembly for wear
- Replace any worn bushings or bearings
- Realign the ledger assembly using the manufacturer's alignment fixture
- Document cutting pressure trends
