The characteristics of HG46/55T CNC machine tool are mainly reflected in their economy and practicality. It adopts a relatively simple structure and control system to meet basic processing needs while reducing costs, making it suitable for small and medium-sized enterprises or individuals to use. This type of lathe usually has high machining accuracy and efficiency, which can meet the machining requirements of general parts.

The tool cannot return to zero: Such faults in CNC milling machine are usually caused by control system failures. You can try to check and replace the switching transistor, because when the switching transistor is damaged, the high-voltage power supply for high-speed return to zero cannot be turned on, resulting in insufficient output torque of the stepper motor and causing return to zero step loss.

The knife holder cannot be locked tightly: This may be caused by the misalignment of the transmitter position, insufficient system reverse locking time, or mechanical locking mechanism failure. This problem can be solved by disassembling the knife holder, adjusting the position of the transmitter disk and the system's anti lock time parameters, as well as checking and repairing the mechanical locking mechanism.

Overshoot or improper rotation of the tool holder: This type of malfunction may be caused by the malfunctioning of the backrest device, spring fatigue, or the tool being too long and heavy. You can check whether the rear positioning pin is flexible, whether the spring is fatigued, and whether the connection between the rear ratchet and the worm is disconnected. Meanwhile, it is also possible to consider replacing the positioning pin spring with a slightly higher elastic modulus.

Overall, the troubleshooting of Machine tool numerical control requires a comprehensive consideration of both mechanical structure and electrical control. When encountering problems, a simple inspection and adjustment should be carried out first. If it cannot be solved, then consider replacing relevant components or seeking professional help. At the same time, regular maintenance and upkeep of the lathe is also an important measure to prevent malfunctions.
