Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a denture cutting machine. Background Art

[0002] Dentures are what people often call "false teeth". Just like calling "false legs" and "false limbs" "artificial limbs", "dentures" mean teeth that fulfill "duties" for humans. In medicine, it is a general term for restorations made after partial or complete tooth loss in the upper and lower teeth. Dentures are divided into two types: removable and fixed. Fixed dentures (commonly known as "fixed dentures") cannot be removed and put on by the patient himself, while removable dentures (commonly known as "removable dentures") can be easily removed and put on by the patient;

[0003] During the denture processing, a cutting machine is usually used to cut metal dentures. Existing cutting machines for cutting dentures usually use magnetic fixation to fix the workpiece, which is not very effective in fixing the denture and is prone to deviation during processing, affecting the processing quality of the denture.
