As a mechanical guiding component, the machining table guide rail 19 ensures that the machining table 22 moves along a forward and backward trajectory, preventing shaking during the operation of the drive device and improving machining accuracy and stability.

[0033] A motor support plate 10 is fixedly installed on the surface of the control box 1 adjacent to the drive motor 9. The motor support plate 10 can prevent displacement of the drive motor 9 due to vibration during operation, thus extending the service life of the equipment.
