Five-axis linkage machining center, also called five-axis machining center, is a machining center with high technological content and high precision specially used for machining complex curved surfaces. Instruments, high-precision medical equipment and other industries have a pivotal influence. The five-axis linkage CNC machining center system is the only means to solve the processing of impellers, blades, marine propellers, heavy generator rotors, steam turbine rotors, large diesel engine crankshafts, etc.

How to maintain the parts of the five-axis machining center?

Five-axis CNC machine tool servo motor and spindle motor components. The servo motor and control system are the crux of the energy source and precision control of the machine tool, focusing on checking the sound and temperature rise. If the sound or temperature rise is too large, it should be determined whether it is a mechanical problem such as a bearing or a parameter setting problem of the compressor that matches it, and take corresponding measures to deal with it. If the servo shaft makes a strange sound when it is stationary, it may be due to the mechanical sound formed by the lead screw, the coupling, and the servo motor not being concentric. The five-axis machining center motor can be disconnected from the coupling and run the motor alone. If the motor still has sound, then adjust the speed loop gain and position loop gain properly to make the motor silent. If there is no sound, it can be determined that it is the concentricity problem between the screw and the coupling of the five-axis machining center. link, the problem can be cleared individually.

Five-axis machining centers measure reactive components. The measuring reaction parts include encoders, grating rulers, etc. It is necessary to check and detect whether the links of each component are loose and whether they can be cleaned by oil or dust. Dust and fine iron scraps may damage such components.

Five-axis machining center electrical control components. Always check whether the external three-phase power supply voltage of the linking machine tool is normal; check whether the electrical components are connected well; use the CRT to display the diagnostic screen to check whether 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 suppressors are effective; check whether the external components of the electrical cabinet of the five-axis machining center are overheated. For poor contact of the contacts of the contactor, the contactor can be disassembled, the low-temperature oxides on the surface of the contacts can be removed with a small file, and then the sundries are wiped out with absorbent cotton and alcohol, reassembled, and then the contacts are checked with a multimeter. Continuity test.

Five-axis machining center CNC system control components. The control system includes numerical control 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 specified range; whether the connection of electrical components is loose; whether the fans of each functional module can operate normally, and remove the dust on the fans and dust filters.
