On the importance of daily maintenance of hard rail CNC lathe manufacturers

In the daily work of hard rail CNC lathe manufacturers, they often make a physical examination of the power supply quality of key equipment, and find abnormalities (excessive harmonic, three-phase imbalance, large voltage fluctuation, etc.), so as to take countermeasures to avoid the production loss of shutdown and the damage of important production equipment. In daily work, we often check the power supply quality of key equipment, find abnormalities (excessive harmonic, three-phase imbalance, large voltage fluctuation, etc.), and take countermeasures to avoid production loss caused by shutdown and damage to important production equipment.

From the perspective of power consumption, the voltage, current or frequency deviation that leads to the failure or failure of electrical equipment is power quality. In addition, some loads will also affect the quality of the power grid during operation, inject harmonics, cause power grid voltage fluctuations, and affect the operation of adjacent loads.

Problems in power supply quality will not only affect the normal and continuous operation of electrical equipment, but also affect the operation efficiency. Hard rail CNC machine tools have high requirements for power supply quality. For example, the voltage amplitude should ensure a certain stability with the change of load, otherwise it will cause various misoperations. The harmonic content should not be too large, otherwise it will overheat, reduce the insulation performance of the equipment, and three-phase imbalance.

In the daily maintenance of hard rail CNC lathe manufacturers, the insulation performance of drive motor and cable needs to be tested regularly. The use of digital insulation meter can greatly improve the maintenance efficiency. Generally, there are oil mist, dust and metal powder in the air of machining workshop. Once they fall on the circuit board or electronic components in the CNC system, it is easy to reduce the insulation resistance between components and even cause damage to components and circuit boards.
