Maintaining a horizontal milling machine isn't actually that complicated; the core points are three: cleaning, lubrication, and standardized operation. Consistent adherence to these methods will significantly extend the machine's accuracy and lifespan.
Daily Maintenance
Cleaning: After each workday, use a cloth and brush to remove chips, oil, and dust, paying particular attention to cleaning moving parts such as guideways and lead screws.
Lubrication:
Guideway Lubrication: Apply lubricating oil to the guideway surface weekly to maintain an intact oil film.
Lubrication System Inspection: Check the oil level, oil pump, and pipelines monthly to ensure adequate lubrication and no leaks.
Other Lubrication Points: Regularly add lubricating oil or grease to bearings, gears, and other components.
Accuracy Inspection: Check the flatness of the worktable and the straightness of the guideways quarterly, and adjust promptly if any decrease in accuracy is detected.
Regular Maintenance
Level 1 Maintenance: Performed approximately every 500 hours of operation by a mechanic and operator. This includes cleaning the lead screw, adjusting guide rail clearance, and inspecting the electrical system.
Level 2 Maintenance: Performed according to the machine's usage and the manufacturer's specifications. This involves more in-depth inspection, adjustment, and repair, and is recommended to be performed by qualified personnel.
