The vertical machining center is a highly automated processing equipment. When it is used for a long time or when it is mishandled, this or that kind of failure will occur. Therefore, we must do daily maintenance work. To this end, Xiao Bing specifically consulted the technicians of Chongqing Jingen CNC Machine Tool Co., Ltd. and obtained the following conclusions:
1. Servo Motors and Spindle Motors of Vertical Machining Centers Some servo motors and control systems are key parts of the machine's power source and precision control, with emphasis on checking noise and temperature rise. If the noise or temperature rise is too great, it should be ascertained whether it is a mechanical problem such as a bearing or a parameter setting problem of a matching amplifier, and take corresponding measures to solve it. If abnormal sound occurs during movement of the servo shaft, it may be due to mechanical noise caused by screw shaft, coupling, or misalignment with the servo motor. It is possible to disconnect the vertical machining center motor from the coupling and run the motor separately. If the motor still has noise, adjust the gain of the speed loop and the gain of the position loop properly to make the motor silent. If there is no noise, judge the concentricity of the screw and the joint, recalibrate the concentricity, and connect it to the motor. The problem can be eliminated generally. .
2. Measuring feedback components of the vertical machining center The measuring feedback components include encoders, grating scales, etc. It is necessary to check frequently whether the connection of each component is loose, whether it is contaminated by oil or dust, and dust and fine iron dust may damage such components. element.
3. The electrical control part of the vertical machining center often checks whether the external three-phase power supply voltage of the connected machine tool is normal; Check whether the electrical component connection is good; Check whether the various switches are effective by means of the CRT display diagnosis screen; Check whether the relays and contactors work properly. , whether the contact is good; thermal relay, arc suppressor and other protective elements are effective; check the vertical machining center electrical cabinet internal components whether the temperature is too high. For poor contactor contact, the contactor can be disassembled, and the high-temperature oxide on the contact surface can be discarded with a small file, then the waste can be wiped out with absorbent cotton and alcohol, reassembled, and then the multimeter can be used to perform the contact. Conduct test.
4, vertical machining center CNC system control part of the control system includes numerical control unit, power module, I / O interface, servo amplifier, spindle amplifier, operation panel, display and so on. In maintenance, it is mainly to check whether the relevant voltage value is within the specified range; whether the connection of electrical components is loosened; whether the fans of each functional module are operating normally, and remove the dust on the fan and filter dust net.
