A vibration engraving machine is a device that uses the principle of vibration for engraving, and its fixing methods generally include the following:

1. Fixing with fixtures: Fix the vibration engraving machine on the worktable, and then use fixtures to fix the workpiece on the worktable. By adjusting the position and angle of the fixture, align the workpiece with the tool of the vibration engraving machine to achieve engraving.

2. Use a chuck to fix: Fix the vibration engraving machine on the workbench, and then use a chuck to fix the workpiece on the chuck. Adjust the position and angle of the chuck to align the workpiece with the tool of the vibration engraving machine, thereby achieving engraving.

3. Use a fixed frame for fixation: Fix the vibration engraving machine on the workbench, and then use a fixed frame to fix the workpiece on the fixed frame. By adjusting the position and angle of the fixed frame, align the workpiece with the tool of the vibration engraving machine to achieve engraving.

The above three methods can effectively fix the vibration engraving machine. The choice of method depends on the shape and size of the workpiece, as well as the precision requirements for engraving.
