We all know that a five-axis machining center is composed of ordinary control electrics, CNC numerical control system, servo control system, alloy castings, hydraulic system, and five-axis transmission system, etc. Its automated processing level and complex processing system are the characteristics of the five-axis machining center as processing equipment. To ensure normal operation without interruption and extend its service life, regular maintenance is necessary. So how should we maintain the commonly used parts of a five-axis machining center?

Five-axis machining centers are currently very effective equipment for manufacturing and processing irregular bodies, boxes, complex cavities, molds, etc. They play a pivotal role in the aerospace, rail transit, automotive interiors, special vehicles, and mold manufacturing industries.

For normal operation without interruption and to extend their service life, regular maintenance is necessary. So how do we usually maintain the commonly used parts of a five-axis machining center?
Today, the editor specifically consulted Nobot's technical personnel and summarized the following points for your reference:
1. Five-axis machining center servo motors and spindle motor components
Servo motors and control systems are the source of energy and the key to precision control for machine tools. Focus on checking sound and temperature rise. If the sound or temperature rise is excessive, it should be determined whether it is a mechanical problem such as bearings or a parameter setting problem with the matching reducer, and the appropriate method should be used to address it. If there is an unusual sound when the servo shaft is stationary, it may be a mechanical sound caused by the ball screw, coupling, or misalignment with the servo motor. The five-axis machining center motor and coupling can be disconnected and the motor run independently. If the motor still makes noise, adjust the speed loop gain and position loop gain appropriately to silence the motor. If there is no sound, it can be determined that there is a concentricity problem with the five-axis machining center ball screw and coupling. Recheck the concentricity and reconnect it to the motor; the problem can usually be eliminated.
2. Five-axis machining center measurement feedback components
Measurement feedback components include encoders and linear scales. Regularly check whether the connections of each component are loose and whether they are contaminated by oil or dust. Dust and fine iron filings can damage these components.
3. Five-axis machining center electrical control components
Regularly check whether the external three-phase power supply voltage connected to the machine tool is normal; check whether the electrical component connections are good; use the CRT display diagnostic screen to check whether various switches are effective; check whether various relays and contactors are working normally and whether the contacts are good; check whether protective components such as thermal relays and arc suppressors are effective; check whether the external components in the five-axis machining center electrical cabinet are overheating. For poor contact of the contactor contacts, the contactor can be disassembled, the low-temperature oxide on the surface of the contacts can be removed with a small file, and then the debris can be wiped off with degreasing cotton and alcohol. Reassemble and use a multimeter to conduct a continuity test on the contacts.
4. Five-axis machining center numerical control system control components
The control system includes the numerical control unit, power module, interface, servo reducer, spindle reducer, operation panel, display, etc. Maintenance mainly involves checking whether the relevant voltage values are within the specified range; whether there is any looseness in the electrical component connections; whether the fans of each functional module are running normally; and cleaning dust from the fans and dust filters, etc.

How to use a five-axis machining center efficiently? Today, let's learn a few practical steps!
When using a five-axis machining center, the equipment must first be adjusted to ensure that the workpiece and fixture dimensions precisely match, and that the zero points of each axis are accurately adjusted.
Why do composite materials require 5-axis CNC machining?
Composite materials are widely used in various fields such as aerospace, automotive, construction, energy, energy storage, infrastructure, marine, pipelines and tanks, sports and entertainment, and transportation due to their light weight, high fatigue resistance, and strong fracture resistance. Among them, aerospace and automotive industries are the largest application markets for composite materials. Five-axis CNC plays an important role in the processing of composite materials. Why do composite materials need to be processed using five-axis CNC?
Dual-station five-axis machines offer several significant advantages. First, while one station is being machined, the other can be used for material loading and unloading, ensuring continuous, non-stop machining and significantly improving production efficiency. Second, the dual-station design makes operation more convenient and reduces waiting time. However, dual-station five-axis machines typically cost more than single-station machines and may require more operating and maintenance space.
