Maintenance Tips
-
Clean after every use: Remove metal punchings and debris from dies, base, and guide plate to keep cuts sharp and accurate.
-
Light lubrication: Apply Durston lubricant or a thin machine oil to punches and guide surfaces to reduce friction and prevent wear.
-
Protect cutting edges: Avoid striking misaligned material—always ensure sheet is flat and properly clamped before cutting.
-
Use correct material thickness: Stay within recommended limits (typically up to ~1mm non-ferrous metal) to avoid damaging punches.
-
Keep clamping system clean: Ensure Allen-key clamp threads are free of swarf so material stays securely fixed.
-
Maintain urethane pad: Replace or rotate when excessively indented to preserve clean cutting action.
-
Prevent rust: Wipe all steel surfaces lightly with anti-corrosion oil after use, especially in humid environments.
-
Store organized: Keep punches in their tray to avoid edge chipping or misalignment from impact
