The core component of the five-axis machining center is the numerical control system, so when maintaining the equipment, we must strengthen the maintenance of the numerical control system, otherwise long-term use will cause damage to the performance of electronic components, and the same is true for mechanical components, so We want to extend the service life of components and the wear cycle of components as much as possible to prevent various failures, so daily maintenance is very important.

Use basic requirements

• The five-axis machining center requires avoiding places with moisture, excessive dust and corrosive gases;

• Avoid direct sunlight and other heat radiation, and precision CNC equipment should be kept away from equipment with large vibrations, such as punching machines, forging equipment, etc.;

• The operating temperature of the equipment should be controlled between 15 degrees and 35 degrees. The precision processing temperature should be controlled at about 20 degrees, and the temperature fluctuation should be strictly controlled;

• In order to avoid the influence of the large fluctuation of the power supply (greater than plus or minus 10%) and possible instantaneous interference signals, the CNC equipment is generally powered by a dedicated line (such as a separate channel from the low-voltage power distribution room for the CNC machine tool), and a voltage stabilizer device is added. etc., can reduce the influence of power supply quality and electrical interference.

Steps to maintain a 5-axis machining center

Formulate rules and regulations for routine maintenance of CNC systems

According to the characteristics of various components, determine your own maintenance procedures. If it is clearly stipulated which places need to be cleaned every day (such as cleaning the input and output units of the CNC system, checking whether the mechanical structure is well lubricated, etc.). Which parts should be regularly checked or replaced (such as DC servo motor brushes and commutators should be checked once a month) .

The doors of CNC cabinets and high-voltage cabinets should be opened as little as possible

Because the air in the machining workshop generally contains oil mist, dust and even metal powder. Once they fall on the printed circuit or electrical device in the numerical control system, it is easy to cause the insulation resistance between the components to drop, and even lead to the damage of the components and the printed circuit. In summer, some users will open the door of the CNC cabinet to dissipate heat in order to overload the CNC system for a long time. This is an inadvisable method that will eventually lead to accelerated damage to the CNC system. The correct method is to reduce the external ambient temperature of the CNC system.

Check whether each cooling fan on the cabinet of the five-axis machining center is working properly every day, and check whether the air duct filter is blocked every six months or quarterly depending on the working environment. If there is too much dust on the filter, it needs to be cleaned in time, otherwise the temperature in the CNC system cabinet will be too high (generally not allowed to exceed 55), causing an overheating alarm or the unreliable operation of the CNC system.

Constantly monitor the grid voltage of the CNC system

The five-axis machining center CNC system produced by Omic CNC allows the grid voltage to fluctuate within the range of 85% to 110% of the rated value. If it exceeds this range, the system will not work properly, and even the electronic components inside the CNC system will be damaged.

Conclusion

The correct operation and maintenance of the five-axis linkage machining center can prevent abnormal wear and tear of the machine tool and avoid sudden failure of the machine tool. Careful maintenance of the machine tool can maintain the long-term stability of the machining accuracy of the machine tool and prolong the service life of the machine tool. This work must be highly valued and executed from the management level of the factory!
