Maintenance checklist
Rotary die maintenance checklist
Use this operator checklist to spot wear, confirm pressure settings, protect paired tooling, and schedule resharpening before performance drifts.
Before the run
- Confirm die serial, anvil, gear, and magnetic cylinder pairing.
- Inspect the die edge, journals, bearers, and anvil surface under good lighting.
- Verify liner, adhesive, caliper, and material stack match the setup sheet.
- Start from the last documented pressure settings instead of over-pressuring the tool.
During the run
- Watch for rising pressure, liner bruising, hanging slugs, fuzzing, or incomplete cuts.
- Log speed, pressure, liner, adhesive, and any operator adjustments.
- Stop and clean adhesive or ink build-up before it masks a die-condition issue.
After the run
- Clean and protect the die edge before storage or shipment.
- Record run counts and symptoms so resharpen intervals are based on production evidence.
- Schedule sharpening when pressure or quality begins to drift from the documented window.
