[0026] The working principle of the utility model is:

[0027] The utility model relates to a CNC engraving and milling machine with adjustable engraving and milling angles. In a specific use process, the overall structure is first moved to a suitable working location, and a servo motor in the middle of the upper end of the right side surface of a supporting plate second drives a long screw on the left side of the servo motor to rotate. The rotation of the long screw causes a movable plate on the surface of the long screw to move left and right on the surface of the long screw under the restriction of a groove first and a groove second. The left and right movement of the movable plate drives the engraving and milling head to move left and right, so that the left and right position of the engraving and milling head can be adjusted. The push rod at the rear side of the electric push rod assembly is driven to move by the electric push rod assembly.
