[0044] During the specific implementation process, for the workpiece on the same turntable 30, the turntable 30 can be first rotated to an operating position convenient for the operation of the vertical milling head (or horizontal milling head). After completing the vertical milling (or horizontal milling) of the workpiece, the turntable is then rotated to an operating position convenient for the operation of the horizontal milling head (or vertical milling head) to complete the horizontal milling (or vertical milling) of the workpiece. In this way, the vertical milling and horizontal milling of a workpiece are completed successively using the workbench 100. Compared with the prior art that requires the use of different CNC machine tools to respectively realize the vertical milling and horizontal milling of a workpiece, the workbench 100 improves the milling processing efficiency of the workpiece. Furthermore, the workbench 100 has a plurality of turntables 30. When the vertical milling head is vertically milling a workpiece on one of the turntables 30, the horizontal milling head can also horizontally mill a workpiece on another turntable 30.

At this time, the support platform 40 is in a stopped rotation state, and the turntable 30 realizes self-rotation through the corresponding driving assembly 10 and the transmission assembly 20; or, when the support platform 40 needs to be rotated, the arc groove 223 of each second docking member 22 can move from the docking protrusion 122 of the corresponding first docking member 12 to the track segment close to it.

[0057] It should be noted that the first docking member 12 can be driven to rotate by the driving component 11 to change the position of the docking protrusion 122 on the first docking member 12 relative to the guide rail 60; in the specific implementation process, the corresponding program can be set so that when the support table 40 needs to be rotated when the workpiece on the turntable 30 completes the milling process, the docking protrusion 122 on the first docking member 12 is in a rotational position relative to the guide rail 60, so that the docking protrusion 122 on the first docking member 12 can be spliced ​​with two adjacent track segments.
