What is the maintenance method of CNC machine tools?

As a CNC lathe parts supplier, share with you. The core of preventive maintenance of CNC machine tools is to improve the maintenance of daily work equipment. Important equipment maintenance work includes: daily inspection, weekly inspection, monthly inspection, quarterly inspection and semi-annual inspection. The maintenance of CNC machine tool prevention equipment is as follows:

1. Daily inspection of CNC machine tools

The important items include hydraulic drive system, Spindle bearing lubrication system, guide rail lubrication system, cooling system and pneumatic operating system. Daily checks are based on the normal conditions of each operating system. For example, when checking the entire process of the spindle bearing lubrication system, the switch power light should be turned on, and the hydraulic pump should be operating normally. If the switching power supply is not turned on, keep the end state of the spindle bearing and contact the mechanical engineer. maintenance. CNC precision machining

2. Weekly inspection of CNC machine tools

Its important items include machine tool parts and spindle bearing lubrication system. Regular inspections should be carried out once a week, especially for machine parts, to remove iron filings and clean external dirt.

3. Monthly inspection of CNC machine tools

Perform switching power supply and air dryer Routine inspections are important. Under normal circumstances, the working voltage of the switching power supply is 180V-220V, and the frequency is 50Hz. If there are any abnormalities, accurate measurements and adjustments must be made. Air dryers should be removed, cleaned and installed monthly.

4. Seasonal inspection of CNC machining tools

The quarterly inspection should be carried out from three aspects Routine inspections: machine tools, hydraulic drive systems and spindle bearing lubrication systems. For example, when performing a routine inspection on a machine tool, it is important to see that the machine accuracy and machine standards meet the requirements in the manual. In case of problems, the mechanical engineer should be contacted immediately. During the routine inspection of the hydraulic transmission system and the main shaft bearing lubrication system, if there is a problem, the new oil 6oL and 20L should be removed and cleaned respectively.

5. Semi-annual inspection of CNC machine tools

After six months, the hydraulic pressure of the machine should be checked regularly Transmission system, lubrication system for spindle bearings and X-axis. If something goes wrong, the new oil should be disassembled and cleaned. After fully understanding and mastering the common sense of preventive maintenance, you must also have a deeper understanding and essential mastery of the causes and treatment of abnormal conditions of the hydraulic operating system. For example, when problems such as oil pump not spraying, abnormal pressure and noise occur, you should know the main reasons and corresponding solutions.
