With the National Day holiday just around the corner, as employees head off for a break, CNC machine tools in factories also require proper shutdown and maintenance. Performing thorough holiday upkeep will help prevent parameter loss and component corrosion, ensuring smooth resumption of operations after the holiday.
✅Key Maintenance Points
1. One week prior to shutdown, check the voltage status of the drive battery and the NC system battery.
2. Ensure the battery is securely installed and making reliable contact; replace it promptly if the voltage is low.
💾II. Back up important data in advance
✅Key Maintenance Points
1. To prevent parameter and program loss due to power outages during the holiday, perform backups in advance for added security.
2. Export the NC parameters, machining program, and compensation data, and save them to a USB flash drive, CF card, or your computer’s local storage.
🛠️ III. Spindle Cleaning and Rust Prevention
✅Key Maintenance Points
1. Remove all tool holders from inside the spindle.
2. Clean the spindle taper and the tool holder.
3. Apply anti-rust oil evenly to the spindle taper and the tool holder surface.
🌫 4. Moisture Protection for Key Components Rust prevention
During long holidays, workshop humidity is high, making metal components highly susceptible to rust.
✅ Maintenance Tips
To Rust‑preventive treatment is applied to metal working surfaces, including the machine table, guard shields, turret, spindle taper bore, and lead screws.
🧹 V. Thoroughly remove metal chips from inside the machine.
✅ Maintenance Tips
Thoroughly remove all residual chips from the machining chamber to prevent moisture‑induced oxidation and corrosion of the metal chips, which could damage machine tool components.
📍 6. Return all axes to their home positions and ensure thorough lubrication.
✅Key Maintenance Points
Move all axes throughout the entire travel range to ensure that the lead screws and guide rails are fully lubricated.
Move the X/Y/Z/A/B axes to the zero position.
The turret, tool magazine, and worktable stop at position 1; the tailstock and robotic arm return to the zero point.
⚠️ 7. Shut off water, electricity, and gas; safely shut down the equipment.
✅Key Maintenance Points
Turn off the machine tool’s main external power supply.
Close the gas supply valve and shut off the water supply.
Confirm all shutdowns and complete the holiday outage.
Perform thorough maintenance on CNC machine tools before the long holiday to minimize the risk of rust and parameter loss, ensuring that equipment can be swiftly put back into production after the break.
