Description

TECHNICAL FIELD

[0002] Glasses generally include glasses legs, glasses frames and lenses. Conventional lenses are mostly of certain degrees, so the shape of the lens has a curved surface, and the shape of the corresponding glasses frame is also relatively complex. In addition, in order to be aesthetically pleasing, glasses frames with variable shapes and unique recognizability need to be designed on the market. Depth design is also made in terms of materials and processes.

[0003] The technology for cutting materials generally includes laser cutting, ultrasonic cutting, numerical control cutting, etc. Laser cutting technology is a technology that uses high-power density laser beams to irradiate the material being cut, heats the material to vaporization temperature very quickly, evaporates to form a hole, and continuously forms a narrow cutting seam as the light beam moves on the material, thereby completing the cutting of the material. In laser cutting of glasses frames, metal glasses frames and glasses frames made of plastic, resin and other materials can be cut with high precision, various complex shapes and patterns can be cut, the cutting speed is fast, the efficiency is high, the heat-affected zone is small, and the size precision and surface quality of the glasses frame can be guaranteed.

[0004] However, the cutting edge of laser cutting is usually perpendicular to the clamping surface, and the cut glasses frame also needs to be polished to form an inclined surface, so that the final shape of the glasses frame is more suitable for the lens. In order to maintain the set shape and avoid deformation, the glasses frame is generally made of high-strength and hard material.
