Introduction

Proper maintenance of CNC digital knife cutting machines is essential to ensure their longevity, accuracy, and efficiency. Regular upkeep helps in avoiding unexpected downtimes and costly repairs. This maintenance manual provides a detailed schedule and procedures for maintaining your CNC digital knife cutting machine.

 Daily Maintenance

Clean the Knife Head

    Procedure: Wipe the knife head with a clean cotton cloth to remove any dust or residue.

Clean the Surface of the Machine

    Procedure: Use an air gun and a rag to clean the machine’s surface, ensuring there is no dust accumulation.

Check the Drag Chain Slot

    Procedure: Ensure the drag chain slot is free of sundries and there is no unusual noise.

Check Operation in X and Y Directions

    Procedure: Run the machine without cutting to check for any unusual noises in the X and Y directions.

Clean the X and Y Rails and Add Grease

    Procedure: Wipe the rails with a cleaning cloth and apply new grease to ensure smooth operation.

Clean the Cutting Tools

    Procedure: Use an alcohol rag to remove any residue from the cutting tools.

Check the Working of Knife Apron and Cutting Tools

    Procedure: Before starting work, check whether the knife apron and cutting tools operate normally.

Check the Oil and Water Inside the Air Compressor

    Procedure: Adjust the drain screw of the air compressor tank to check and remove any water accumulation.

Check the Total Pressure Value

    Procedure: Ensure the standard air pressure is 0.6 Mpa (0.8 Mpa if using a pneumatic knife).

Check the Air Pressure Valve

     Procedure: Confirm there is no water inside the air pressure valve.

Check Screws on the Tool Apron and Knife Head

     Procedure: Ensure all screws are tight and none are loose or missing.

Clear the Surface of Felt
