Pre-shift Maintenance
Check all oil sump levels for oil shortage and, according to the lubrication diagram, add clean machine oil. Vertical milling machines require lubrication during use; lubrication must be performed at the specified intervals to ensure normal machine operation.
Check the power switch for proper appearance and function, and ensure the grounding device is intact. Electrical equipment is a crucial component of the vertical milling machine and its proper functioning must be guaranteed.
Check all screws, bolts, handles, knobs, and oil cups for looseness and missing parts. Tighten or replace any found. Loose or missing parts will affect the machine's accuracy and stability.
Check the condition of the drive belts. Drive belts are a vital transmission component of the vertical milling machine; their tension must be appropriate, and they must not show wear or cracks.
Check the electrical safety devices for proper functioning. Electrical safety devices are essential for operator safety and must be guaranteed to function correctly.
Daily Maintenance of Vertical Milling Machines
In-Shift Maintenance
Observe the sensitivity, reliability, temperature rise, noise, and vibration of the motor and electrical components. The motor and electrical components are essential parts of the vertical milling machine and must be ensured to operate normally.
Check the sensitivity and reliability of the electrical safety devices. Electrical safety devices are crucial protective measures for operator safety and must be ensured to operate normally.
Observe the temperature rise, noise, and vibration of each transmission component. Transmission components are essential parts of the vertical milling machine and must be ensured to operate normally.
Constantly check the operation of the plunger oil pumps in the bed and lifting table. If no oil flows from the indicator while the machine is running, repair it promptly. The plunger oil pump is a critical lubrication component of the vertical milling machine and must be ensured to operate normally.
If axial clearance of the longitudinal leadscrew of the worktable or transmission clearance is found, adjust it according to the instructions. Adjusting the axial clearance of the leadscrew of the worktable and transmission clearance is an important measure to ensure the accuracy and stability of the vertical milling machine.
Adjustment of the spindle bearings. The spindle bearing is a crucial component of a vertical milling machine, and its proper functioning must be ensured.
Adjustment of the rapid traverse clutch on the worktable. The rapid traverse clutch on the worktable is a crucial component of a vertical milling machine, and its proper functioning must be ensured.
Adjustment of the drive belt tension. The tension of the drive belt is an important measure to ensure the transmission stability of a vertical milling machine.
Regular Maintenance
Regularly change the machine's lubricating oil. Vertical milling machines require lubrication during use, and the lubricating oil must be changed on schedule according to the prescribed intervals. When changing the lubricating oil, impurities inside the machine's lubrication system must be cleaned to ensure the normal operation of the lubrication system and protect critical components such as bearings.
Regularly clean the machine. Regularly cleaning the machine helps prevent wear and tear and malfunctions, ensuring the machine's normal service life.
