[0002] The glasses frame is an important component of the glasses. The materials mainly include metal, plastic, resin or natural materials. There are full-frame, half-frame and frameless types. The glasses frame needs to be made of glasses frame plates. During the processing of the glasses frame, holes need to be punched in the glasses frame so that the legs of the glasses can be connected to the frame for mounting the lenses through screws.

[0004] When punching holes in eyeglass frames, a pressing mechanism is usually used to press and fix the frames. During the punching operation, certain friction and impact force will be generated. Therefore, the frame is easily deformed due to the pressure or uneven force during the punching, and the hole position may be offset.

[0005] In summary, the present application now proposes a CNC device for processing eyeglass frames to solve the above-mentioned problems. Summary of the invention
