Daily maintenance of vertical milling machine

The daily maintenance of a vertical milling machine is a key step in ensuring its long-term stable operation and machining accuracy. The following are detailed instructions for daily maintenance of vertical milling machines:

1、 Check before startup

Oil pool inspection: Check whether each oil pool is short of oil, and add clean engine oil according to the lubrication diagram to ensure that each lubrication point is fully lubricated.

Power and Grounding: Check the appearance and function of the power switch, and whether the grounding device is complete to prevent electrical faults and electric shock risks.

Fastener inspection: Check whether the screws, handles, handballs, and oil cups of each component are loose or missing. If found, they should be tightened and replenished in a timely manner to prevent faults caused by looseness.

Drive belt inspection: Check the condition of the drive belt to ensure that it is not worn, broken, or loose, in order to ensure transmission efficiency.

Electrical safety devices: Check whether the electrical safety devices are in good condition, including emergency stop buttons, limit switches, etc., to ensure that the power can be quickly cut off in emergency situations.

2、 Observation during operation

Observation of motors and electrical appliances: Observe the sensitivity, reliability, temperature rise, sound, and vibration of motors and electrical appliances. If any abnormalities are found, stop the machine for inspection in a timely manner.

Observation of transmission components: Observe the temperature rise, sound direction, and vibration of each transmission component to ensure smooth transmission and no noise.

Oil pump operation inspection: Always check the working condition of the plunger oil pump in the bed and lifting platform. When the machine tool is running and there is no oil flowing out of the indicator, it should be repaired in a timely manner.

3、 Regular adjustment and maintenance

Gap adjustment: When the axial clearance of the worktable’s longitudinal lead screw and the transmission have gaps, adjustments should be made according to the instructions to eliminate the gaps and improve machining accuracy.

Bearing adjustment: Adjust the spindle bearings to ensure smooth and noise free operation.

Clutch adjustment: Adjust the clutch for quick movement of the workbench to ensure smooth engagement and disengagement.

Belt tightness adjustment: Adjust the tightness of the transmission belt to prevent transmission problems caused by over tightening or over loosening.

4、 Daily cleaning and maintenance

Cleaning work: After daily use, the chips, iron filings, and other debris on the vertical milling machine should be cleaned to avoid damage or malfunction to the equipment. At the same time, regularly clean the lubricating oil tanks inside the bed, the lifting platform, and the worktable base, as well as the oil filter of the lubricating oil pump.

Lubrication work: Each lubrication point of the vertical milling machine should be regularly lubricated to ensure the lubrication effect of the machine tool. According to the frequency of use of the equipment, the lubrication cycle can be set to once a week or once every two weeks. In addition, the lifting screw should be lubricated with aluminum disulfide oil every two months.

Tool and trimmer inspection: Regularly check the wear level of the tool to ensure that it meets the requirements. At the same time, check and calibrate the micro adjuster to ensure the stability of machining accuracy.

5、 Long term storage and maintenance

If the vertical milling machine is not used for a long time, it should be stored in a dry and ventilated place, and regularly cleaned and lubricated to maintain the good condition of the equipment. Before storage, a comprehensive inspection of the machine tool is required to ensure that all components of the equipment are free from faults and damage.

In summary, the daily maintenance of vertical milling machines involves multiple aspects such as pre startup inspection, observation during operation, regular adjustment and maintenance, daily cleaning and maintenance, as well as long-term storage and maintenance. Only by following the correct maintenance methods and cycles can the long-term stable operation and machining accuracy of the vertical milling machine be ensured.
