The invention belongs to the technical field of glass production, and particularly relates to a cutting device with a section polishing function for glass production, and the cutting device aims to solve the problem that glass cutting errors of a glass cutting knife are relatively great as glass cannot be reliably clamped and fixed, only a glass cutting device is provided while a glass cut grinding device is not provided, and motion precision is not high. The cutting device is characterized by comprising a fixed bottom plate, wherein fixed housings are welded on outer walls of the two sides ofthe top of the fixed bottom plate, wherein the inner parts of the two fixed housings are welded with bearing bases. The cutting device can stably clamp and fix glass plates, is high in positioning precision, guarantees glass plate cutting precision, can realize cutting and polishing operation on the glass plate, performs various-way processing on the glass plate, improves glass plate processing efficiency, is more flexible to move, and is suitable for processing glass plates of different specifications.
