[0026] In one embodiment, a workpiece support 8 is arranged at the front of the spring chuck below the clamped workpiece, and the workpiece support 8 is driven by a lifting cylinder 7 to move up and down. The workpiece support is used to provide auxiliary support for the workpiece to ensure the stability of the processing.

[0027] Specifically, the workpiece support 8 forms an "L"-shaped notch at the upper end to support the workpiece body.

[0028] Specifically, the lifting cylinder 7 is installed on the A-axis rotating motor pad 6 .

[0029] Specifically, the multi-directional horizontal traverse mechanism 3 includes an X-axis horizontal traverse mechanism, and a Y-axis traverse mechanism is arranged below the X-axis horizontal traverse mechanism. The position of the workpiece clamping fixture is adjusted by the coordinated movement of the X-axis and the Y-axis.
