Finally, chuck 4 is moved by slide table 3, so that the workpiece can be engraved and milled by the main body 1 of the engraving and milling machine. During the processing, chuck 4 can prevent the workpiece from shifting.

[0032] After the workpiece is processed, the operator controls the slide table 3 to reset and release the workpiece. The workpiece can then be unloaded through the support table 13, cylinder 15 and clamping assembly 16. The loading and unloading port 6 ensures that the workpiece passes through the bracket 5, avoiding the bracket 5 from obstructing the loading and unloading of the workpiece. During the loading and unloading process, the support rod 1403 of the guide assembly 14 can support and guide the support table 13 through the rod sleeve 1404, which can ensure the stability and load-bearing capacity of the support table 13. At the same time, it can prevent the load of the support table 13 from being transmitted to the ball screw 8, and the ball screw 8 is not easily deformed.
