How to perform daily maintenance on CNC machine tools

In order to extend the service life of the machine tool, confirm the normal operation of the various functions of the machine tool, and ensure the accuracy of the machine tool, it is necessary to do a good job in daily maintenance of the machine tool, and conduct regular confirmation and inspection. Let’s share the frequency and method of machine tool maintenance.

1. Daily inspection: The main items include hydraulic system, spindle lubrication system, guide rail lubrication system, cooling system, and pneumatic system. The daily inspection is based on the normal conditions of the system. For example, when performing process inspection of the spindle lubrication system, the power light is on and the oil pressure pump should be running normally. If the power light is not on, the spindle should be kept stopped and communicate with the machinist. Contact us for repairs.

2. Weekly inspection: Its main items include machine tool parts and spindle lubrication system, which should be correctly inspected every week. In particular, iron filings should be removed from machine tool parts and external debris should be cleaned.

3. Monthly inspection: mainly inspect the power supply and air dryer. Under normal circumstances, the power supply voltage has a rated voltage of 180v~220v and a frequency of 50hz. If there is any abnormality, it must be measured and adjusted. The air dryer should be disassembled, cleaned and assembled once a month.

4. Quarterly inspection: Mainly inspect the machine tool bed, hydraulic system, and spindle lubrication system. For example, when inspecting the machine tool bed, it mainly depends on whether the accuracy and level of the machine tool meet the requirements in the manual. If there are any problems, you should contact the machinist immediately. When checking the hydraulic system and spindle lubrication system, if there are any problems, replace them with new oil and clean them respectively.

5. Semi-annual inspection: After half a year, the hydraulic system, spindle lubrication system and X-axis of the machine tool should be inspected. If any problems occur, new oil should be replaced and cleaned.
