Two radial spindle fixing holes 26 are provided at the top end of the support frame 2, and an xy stage 51 is supported on the support frame 2 around the radial spindle fixing holes 26, from which radial spindle fixing holes 26 the tool is extended to the position of the workpiece 100.

The radial main shaft system is also provided with a waterproof structure which is basically the same as the waterproof structure of the docking device, but has slightly different shapes.

The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention, which is defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
