Manhart What are the common causes of faults in CNC circular machines?

In daily use, comprehensive maintenance and upkeep are necessary to extend the service life of CNC circular machines. Here are some key maintenance and upkeep measures:
###1、 Regular cleaning
1. * * Machine tool cleaning * *:
-Regularly clean the workpieces, fixtures, iron filings, and other debris inside and outside the machine tool to keep it clean.
-Clean the iron filings inside the external chip conveyor to prevent blockages from affecting the chip removal effect.
-Wipe the external sheet metal of the machine tool to keep it clean and dust-free.
-Regularly clean the filter screens of the electrical control box, air conditioner, and oil cooler to ensure smooth air circulation and prevent dust accumulation from affecting the heat dissipation effect.
2. Anti oil pollution treatment:
-Regularly clean the oil stains on the surface of the machine tool to prevent the accumulation of oil stains from causing equipment corrosion or affecting accuracy.
-Regularly inspect and clean the lubrication system, replace aged lubricating oil, and keep the lubrication system unobstructed.
###2、 Mechanical component maintenance
1. * * Transmission system inspection * *:
-Regularly inspect transmission components such as belts, chains, gears, etc. for wear or looseness, and replace or tighten them in a timely manner.
-Check the wear of bearings, guide rails, and other components, add lubricants in a timely manner, and maintain good lubrication.
2. * * Spindle and tool maintenance * *:
-Check the fastening of the spindle to prevent it from loosening and causing a decrease in machining accuracy.
-Regularly check the wear of cutting tools, replace severely worn tools in a timely manner, and ensure machining quality and efficiency.
3. * * Structural component inspection * *:
-Regularly check whether the structural components of the machine tool are deformed or loose, and adjust and tighten them in a timely manner.
-Pay special attention to the stability of key components such as the base and columns of the machine tool to prevent instability caused by vibration or external forces.
###3、 Electrical system maintenance
1. * * Power check * *:
-Regularly check whether the power supply voltage is stable to prevent equipment damage caused by voltage fluctuations.
-Check if the power supply circuit is aging or has poor contact, and replace damaged power cords and plugs in a timely manner.
2. Electrical component inspection:
-Regularly check the working status of electrical components such as motors, relays, contactors, switches, etc., and replace damaged components in a timely manner.
-Check whether the control circuit is short circuited, open circuited, or has poor contact to ensure accurate and reliable signal transmission.
3. Maintenance of PLC and servo system:
-Regularly check the operation status of PLC programs and servo drives to ensure that the programs are error free and the drives are working properly.
-Regularly calibrate the position accuracy of servo motors and encoders to ensure the motion control accuracy of the machine tool.
###4、 Software and Program Maintenance
1. * * Software Update * *:
-Regularly check the software version of the CNC system and update the software in a timely manner to fix known vulnerabilities and defects.
-Maintain contact with machine tool manufacturers to obtain the latest software updates and technical support.
2. * * Program backup * *:
-Regularly backup machining programs and system parameters to prevent data loss from causing the machine tool to malfunction.
-Regularly check the integrity and availability of backup data to ensure quick recovery when needed
###5、 Operation and Environmental Management
1. * * Standardized operation * *:
-Strictly follow the operating procedures and safety regulations of the machine tool to prevent damage to the machine tool or personal injury caused by misoperation.
-Regularly train and assess operators to improve their skills and safety awareness.
2. * * Environmental Control * *:
-Maintain the temperature, humidity, and cleanliness of the environment where the machine tool is located within a reasonable range to prevent adverse effects of environmental factors on the machine tool.
-Pay special attention to dust and moisture prevention work to prevent dust and moisture from entering the interior of the machine tool and causing malfunctions.
###6、 Regular maintenance and inspection
1. * * Develop a maintenance plan * *:
-Develop a detailed maintenance plan based on the usage of the machine tool and the manufacturer’s recommendations, and strictly follow the plan.
-The maintenance plan should include regular cleaning, inspection, replacement of vulnerable parts, and adjustment of parameters.
2. * * Professional maintenance services * *:
-Regularly invite professional machine tool maintenance personnel to conduct comprehensive inspections and maintenance services on machine tools.
-Timely identify and address potential faults and hazards to ensure that the machine tool is always in good working condition.
By implementing the above measures, the service life of CNC circular machines can be effectively extended, the reliability and stability of equipment can be improved, and strong guarantees can be provided for the production of enterprises.
