We all know that the five-axis machining center is composed of ordinary control electrical, CNC numerical control system, servo control system, alloy castings, hydraulic system and five-axis transmission system. Its automatic processing level and complex processing system are the characteristics of the five-axis processing center as a processing equipment. To use the unobstructed normally and extend its service life, it must be protected and maintained regularly. So how do we usually protect the common parts of a five-axis machining center?
1. Servo motor and spindle motor components of five-axis machining center
Servo motors and control systems are the crux of the source of energy and precision control of machine tools, and focus on sound and temperature rise. If the sound or temperature rise is too large, it should be ascertained whether it is a mechanical problem such as a bearing or a parameter setting problem of a matching reducer, and adopt corresponding measures to deal with it. If the servo shaft is at rest, if there is a strange sound, there may be mechanical sounds that can be caused by the lead screw, the coupling, and the servo motor. You can disconnect the five-axis machining center motor from the coupling and run the motor alone. If the motor still has sound, adjust the speed loop gain and status loop gain appropriately to make the motor silent. If there is no sound, it can be determined that it is the concentricity of the five-axis machining center screw and coupling. Check the concentricity again, and then reconcile it with the motor. Links, individual problems can be cleared.
2. Measuring reaction element of five-axis machining center
The measuring reaction parts include encoders, grating scales, etc. It is necessary to check whether the links of the various components are loose and whether they can be cleaned by oil or dust. Dust and small iron filings may damage such components.
3. Electrical control components of five-axis machining center
Always check whether the external three-phase power supply voltage of the connected machine tool is normal; check whether the electrical components are connected well; use the CRT to display the diagnostic screen to check whether the various switches are effective; check whether the relays and contactors work normally and whether the contacts are Good; whether the protective components such as thermal relays and arc restrainers are effective; check whether the external components of the electrical cabinet of the five-axis machining center are overheated. Regarding the poor contact of the contactor, the contactor can be disassembled, and the low-temperature oxide on the surface of the contact can be frustrated with a small file, and then wipe out the debris with absorbent cotton and alcohol, reassemble, and then use a multimeter to perform Continuity test.
4. Five-axis machining center CNC system control components
The control system includes CNC unit, power module, interface, servo reducer, spindle reducer, operation panel, display, etc. In the protection, it is important to check whether the relevant voltage values are within the regulated scale; whether the electrical component links are loose; whether the fans of each function module are running normally, and to remove the dust on the fans and dust filters.
