Slitting machine daily maintenance checklist: 6 simple steps to reduce equipment failure rate

The following is a concise list of 6 steps for the daily maintenance of the slitter to help effectively reduce the failure rate and extend the life of the equipment:

1. Cleaning and maintenance (daily/per shift)

• Blades & Rollers: Use a soft cloth to clean up debris and glue stains to avoid scratching the surface (operation after stopping).

• Fuselage and guide rail: remove dust and oil to prevent impurities from entering the transmission parts.

• Dust collection device: empty the waste bin and check whether the suction pipe is blocked.

2. Lubricate key areas (weekly/50 operating hours)

• Rails and bearings: Use special grease to apply linear guides and housings.

• Transmission chain/gear: add anti-wear lubricating oil drip, wipe off excess oil stains and prevent sticky dust.

• Pneumatic components (if any): Add 1-2 drops of light oil to the gas valve fittings.

3. Blade inspection and maintenance (per shift/during material change)

• Sharpness: Observe the quality of the cut surface and sharpen or replace the burrs in time.

• Installation status: Confirm that the blade is tightened without loosening and the angle is not offset.

• Anti-rust treatment: Apply anti-rust oil protection when the machine is shut down for more than 24 hours.

4. Drivetrain Inspection (Weekly)

• Belt/coupling: check the tightness without cracks or slippage.

• Servo motor: clean the heat dissipation hole, monitor for abnormal noise or overheating (temperature < 60°C).

• Gearbox: When the oil level is insufficient, the lubricating oil of the specified model is replenished.

5. Electrical & Safety Devices (Daily)

• E-stop button: test response sensitivity.

• Sensor/photoswitch: Clean the sensor head to ensure position alignment.

• Wiring: Check that there is no exposure, aging, and the joints are tight.

6. Parameter calibration (monthly/when switching materials)

• Tension system: Use standard weights to check whether the tension value is accurate.

• Correction device: test the automatic correction function and adjust the sensitivity.

• Slitting accuracy: measurement width error after cutting 100 meters of material (within ±0.2mm).

⚠️ Additional tips

• Record maintenance logs: including date, operator, and abnormal conditions.

• Wearing parts inventory: Keep blades, belts, etc. on hand to avoid downtime and waiting for parts.

• Operational training: non-professionals are prohibited from adjusting core parameters.

By regularly implementing these 6 steps, sudden failures can be reduced by more than 60% and production efficiency can be significantly improved. When encountering complex problems, it is recommended to contact the manufacturer's technical support.
