What are the maintenance of CNC machining CNC machine tools?

CNC machining CNC machine tools as a modern processing industry technology, its own maintenance is very critical.
Maintenance like machinery generally includes daily maintenance, weekly maintenance, monthly maintenance, quarterly maintenance, and semi-annual maintenance. Let's take a look at how to operate.
I. Daily maintenance of CNC machining CNC machine tools the main items include hydraulic system, spindle lubrication system, guide rail lubrication system, cooling system and air pressure system.
Daily inspection is based on the normal conditions of each system.
For example, when the process inspection of the spindle lubrication system is carried out, the power lamp should be on, the oil pressure pump should operate normally, and if the power lamp is not on, the spindle should be kept in a stop state and the mechanical engineer should be contacted. Repair.
Second, about the weekly maintenance of CNC machining CNC machine tools its main items include machine tool parts, spindle lubrication system, should be checked correctly every week, especially for machine tool parts to remove iron filings, carry out external debris cleaning.
Third, the monthly maintenance of CNC machining CNC machine tools is mainly to check the power supply and air in the dryer.
The power supply voltage is rated at 180V under normal conditions-
220 V, frequency 50Hz, if there is any abnormality, it should be measured and adjusted.
The air should be disassembled once a month and then cleaned and assembled.
Four, about CNC machining CNC machine tool quarterly maintenance inspection should be mainly from the machine bed, hydraulic system, spindle lubrication system three aspects of inspection.
For example, when checking the machine bed, it is mainly to see if the machine tool accuracy and machine tool level meet the requirements in the manual. If there is any problem, you should contact the mechanical engineer immediately.
When inspecting the hydraulic system and the spindle lubrication system, if there is any problem, replace the new oil 6oL and 20L respectively and clean it.
5. After half a year of maintenance and maintenance of CNC machining CNC machine tools, the hydraulic system, spindle lubrication system and x-axis of the machine tool should be inspected. If there is any problem, new oil should be replaced, then carry out the cleaning work.
After fully familiarizing yourself with and mastering the knowledge of preventive maintenance, you must also have a deeper understanding and necessary mastery of the causes and handling of abnormal phenomena in the oil pressure system.
For example, when the oil pump does not inject oil, the pressure is abnormal, there is noise and other phenomena, we should know what the main reasons are and what corresponding solutions are available.
