    Global Servo CNC maintenance center

    Global Servo CNC maintenance center,Professional maintenance of servo CNC systems

    Remember to contact Longi Electromechanical for any issues with servo and CNC systems!

    Servo systems differ from VFDs in that they offer higher precision and typically come with delicate encoders. Servo motors are synchronous motors with magnets inside, and if not handled carefully during disassembly and assembly, their original performance may not be restored. Additionally, different servo drivers cannot be used interchangeably with other servo motors. This means that during the repair of a servo driver, a corresponding servo motor and cable plug are required for proper testing. Similarly, repairing a servo motor also requires a matching servo driver for testing, which can pose challenges for many maintenance personnel.

    As for CNC (Computer Numerical Control) systems, most are embedded industrial computer types with closed control systems. Each manufacturer has its own design ideas, programming methods, wiring, and communication architectures, making them incompatible with one another.

    Longi Electromechanical Company has designed various styles of servo and CNC maintenance test benches to test the working conditions of different CNC systems, servo drivers, or servo motors. When servo systems encounter issues such as no display, phase loss, overvoltage, undervoltage, overcurrent, grounding, overload, module explosion, magnet loss, parameter errors, encoder failures, communication alarms, etc., the corresponding platform can be used to test and diagnose the problem.

    Repair Hotline: +8618028667265 Mr. Guo

    After resolving these issues, the servo system also needs to undergo a simulated load test to avoid problems such as overcurrent under load conditions, even if it performs well under no-load conditions. This ensures that the servo system is fully functional and ready for use in actual applications.

    For the CNC system, it is also necessary to conduct simulated operation before normal delivery to avoid any discrepancy with the on-site parameters. Currently, Rongji Electromechanical possesses hundreds of servo and CNC test benches, which can quickly identify problem areas and promptly resolve issues. With these advanced testing facilities, Longi Electromechanical ensures the smooth operation and reliability of the repaired equipment.

    The Servo and CNC Repair Center established by Longi Company currently has over 20 skilled and experienced maintenance engineers who specialize in providing repair services for different brands and specifications of servo and CNC systems. They implement tailored repair solutions for different maintenance projects, ensuring efficient and high-quality service for customers. By helping customers save valuable production time and reducing their maintenance costs, Rongji truly cares about the urgent needs of its customers and strives for common development and progress together.
