CNC machine tools have promoted the development of high-speed machining technology. Power supply is crucial for machine tools. It is the energy support part that maintains the normal operation of the system. The direct result of its failure or malfunction is the shutdown or destruction of the entire system. In addition, some operating data, setting data, and machining programs of the CNC system are generally stored in RAM memory. After the system is powered off, they are maintained by the backup battery or lithium battery of the power supply. Therefore, the downtime is relatively long, and unplugging and unplugging power or memory may cause data loss, making the system unable to operate. Meanwhile, due to the use of three-phase AC 380V power supply in CNC equipment, safety is also an important part of the pre installation work of CNC equipment. Based on the above reasons, there are strict requirements for the power supply used in CNC equipment: the voltage fluctuation of the power grid should be controlled between+10% and -15%. In the case of large power fluctuations and poor quality, combined with the interference of high-frequency pulses, Or human factors (such as sudden power outage, etc.). During peak electricity periods, such as about an hour before work or off duty during the day, and at night, there is often a significant deviation, even reaching ± 20%. Causing the machine tool to alarm and unable to function properly, and causing damage to the machine tool power system. Even leading to the loss of relevant parameter data, etc. Our solution Install an AC stabilized power supply system with automatic compensation and adjustment function in workshops with concentrated CNC machine tools; A single CNC machine tool can be equipped with a separate AC voltage regulator to solve the problem. We can provide a safe solution for your CNC machine tool to operate steadily and safely.
