Daily maintenance and maintenance of CNC lathes
The lathe has the characteristics of machine, electricity and liquid. It is technology-intensive and knowledge-intensive. It is an advanced processing equipment with high degree of automation, complicated structure and high cost. In order to give full play to its benefits and reduce the occurrence of faults, daily maintenance work must be done. Therefore, CNC lathe maintenance personnel are required to have not only knowledge of machinery, processing technology and hydraulic and pneumatic, but also electronic computers, automatic control, drive and measurement. Knowledge and other knowledge, in order to fully understand and master the CNC lathe, and do a good job in maintenance.
1. The main daily maintenance and maintenance work of CNC machine tools: Choosing the right environment for use: The environment in which CNC lathes are used (such as temperature, humidity, vibration, power supply voltage, frequency and interference) will affect the normal operation of the machine tool, so When installing the machine tool, it is strictly required to meet the installation conditions and requirements specified in the machine tool specification. Under the conditions of economic conditions, CNC lathes should be installed separately from ordinary machining equipment for easy maintenance and maintenance.
2. Specialized personnel who should be equipped with CNC system programming, operation and maintenance for CNC lathes: these personnel should be familiar with the mechanical parts of the machine tools used, CNC systems, high-voltage equipment, hydraulic pressure, air pressure, etc., and the use environment, processing conditions, etc. Use the CNC lathe correctly according to the requirements of the machine and system instruction manual.
3, long-term maintenance and maintenance of CNC lathes: When the CNC lathe is idle, it should be energized by the CNC system, and it will run empty when the machine is locked. In the mildew rain season where the air humidity is high, it should be energized every day. The heat of the electrical components itself is used to drive away the moisture in the CNC cabinet to ensure the stable and reliable performance of the electronic components.
4. Maintenance and maintenance of the hardware control part of the CNC system: Have an experienced maintenance electrician check it once a year. Check whether the relevant reference voltage is within the specified range, such as the output voltage of each power module, the reference voltage of the numerical control unit, etc., if it is not normal and remove dust; check whether the connection of various electrical components in the system is loose; check that each functional module uses fan operation. Whether it is normal and remove dust; check whether the connection of the external regenerative discharge unit used by the servo amplifier and the spindle amplifier is reliable, remove dust; check whether the voltage of the memory backup battery used by each function module is normal, and should be replaced regularly according to the manufacturer's requirements. For machines that have been deactivated for a long time, they should be turned on for 4 hours per month, which can extend the service life of CNC machine tools.
5. Maintenance and maintenance of the mechanical part of the machine tool: After the end of each shift, the operator should clean the chips scattered on the carriage, rails, etc.; during the work, pay attention to check whether the chip conveyor is normal to avoid chip accumulation and damage the guide rail. Accuracy, endangering the life of the ball screw and the guide rail; before the end of the work, each servo axis should be returned to the origin and stopped.
6. Maintenance and maintenance of machine tool spindle motor: The maintenance electrician should check the servo motor and spindle motor once a year. Focus on checking its operating noise and temperature rise. If the noise is too large, you should find out the cause, whether it is a mechanical problem such as a bearing or a parameter setting problem of the amplifier that matches it, and take corresponding measures to solve it. For DC motors, brushes, commutators, etc. should be inspected, adjusted, repaired or replaced to make them work well. Check that the cooling fan at the end of the motor is running properly and clean the dust; check if the motor's coupling plugs are loose.
7. Maintenance and maintenance of machine feed servo motor: For the servo motor of CNC lathe, maintenance should be carried out in 10~12 months. The machine with frequent acceleration or deceleration changes should be maintained in 2 months. The main contents of maintenance are: use the dry compressed air to blow off the dust of the brush, check the wear of the brush. If you need to replace it, you need to select the brush with the same specification. After the replacement, you need to run it for a certain period of time. Check the surface of the device; check the armature commutator to prevent short circuit; if equipped with a tachometer motor and pulse encoder, also check and clean. The DC servo motor in the CNC lathe should be inspected at least once a year. Generally, it should be checked under the condition that the CNC system is powered off and the motor is completely cooled. Remove the rubber cap and unscrew the brush cap with a screw driver. Take out the brush; measure the brush length. If the brush of FANUC DC servo motor is worn from 10mm to less than 5mm, the same type of brush must be replaced; carefully check the arc contact surface of the brush for deep grooves and cracks, and Is there any trace of ignition on the brush spring? If the above phenomenon occurs, it is necessary to consider whether the working condition of the motor is excessively bad or whether the motor itself has a problem. The compressed air containing the metal powder and moisture is introduced into the brush hole of the charging brush, and the brush powder adhering to the wall of the brush hole is blown. If it is difficult to blow, use a screw tip to clean it gently until the hole walls are clean, but be careful not to touch the commutator surface. Have a new brush and tighten the brush cover. If a new brush is replaced, the motor should be run dry for a period of time to match the brush surface to the commutator surface.
