CNC lathes are indispensable precision equipment in modern manufacturing, and their daily maintenance is crucial to maintaining machine performance, extending service life and ensuring production efficiency. The correct maintenance method can not only reduce the occurrence of failures, but also improve the processing accuracy and stability. Next, you will be introduced to how to properly maintain CNC lathes in daily use to ensure that the equipment is in the best working condition.

The operating environment of CNC lathes has a direct impact on the normal operation of machine tools. Ensure that the machine is installed under the conditions specified in the manual, such as temperature, humidity, vibration, power supply voltage, etc. If economic conditions permit, it is best to isolate CNC lathes from ordinary machining equipment to facilitate repair and maintenance, while avoiding adverse effects of external factors on the machine tool.

It is necessary to equip CNC lathes with professionals who are familiar with mechanical, electrical, hydraulic, pneumatic and other systems and the use environment. These personnel should be able to correctly use CNC lathes according to the requirements of the machine tool and system operating instructions, and regularly check and maintain the machine tool to ensure its normal operation.

Every year, an experienced maintenance electrician should check the hardware control part of the CNC system, including detecting the reference voltage, removing dust, checking whether the connection of electrical components is loose, and whether the fan is running normally. For long-term deactivated machine tools, start and run for 4 hours per month, which can extend the service life of CNC machine tools.

When the CNC lathe is idle, the CNC system should be powered on regularly to make it run empty, especially in the season of high air humidity, it should be powered on every day, and the electrical components themselves can heat away the moisture in the CNC cabinet to ensure the stable and reliable performance of the electronic components.

After the end of each shift, the operator should clean the chips in time to keep the drag plate, guide rail and other places clean. When working, pay attention to check whether the chip removal device is normal to avoid the accumulation of chips and damage the accuracy of the guide rail. Before the end of the work, each servo shaft should be stopped after returning to the origin to reduce the thermal deformation of the machine tool.

Maintenance electricians should check the servo motor and spindle motor once a year, focusing on checking their operating noise and temperature rise, identifying the causes and taking appropriate measures to solve, whether it is a mechanical problem such as bearings or a parameter setting problem with the amplifier.

The daily spot check of CNC machine tools includes hydraulic system, spindle lubrication system, guide rail lubrication system, cooling system, air pressure system, etc. Daily inspection, weekly inspection, monthly inspection, quarterly inspection, semi-annual inspection and other regular inspection to ensure the normal operation of the machine system, timely detection and treatment of potential problems.

Clean the surface and inside of the machine regularly, remove oil and chips, and keep the machine clean inside and outside. Check the lubricating oil plane to ensure that the oil is sufficient, fill the lubricating oil in time, and maintain the good lubrication of the moving parts of the machine tool.

The daily maintenance of CNC lathes is a systematic project, which requires the joint efforts of operators and maintenance personnel. Through the above maintenance measures, it can effectively prevent failures, extend the service life of the machine tool, and improve production efficiency and processing quality. Therefore, the establishment of a complete maintenance system and the regular implementation of maintenance plans are the key to ensuring the efficient and stable operation of CNC lathes.
