Technical Field

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

[0002] Engraving machine is an automated processing equipment controlled by computer. It carves different beautiful patterns and texts on the surface of wood, plastic, copper and other materials through the cutting action of tungsten steel and other materials. Engraving machines are widely used in furniture manufacturing, building decoration, art production and other fields.

[0003] Among them, the digital denture engraving equipment, as the output link of the digital process flow, is the technical means to realize the final production of the denture. Its working principle is to first use the numerical control process planning software to generate a processing process file that can be recognized by the CAM equipment through the denture digital model designed by the CAD software. The CAM equipment is then controlled by precise software programs to execute the processing procedures in the corresponding process files, thereby completing the production of dentures that meet certain precision requirements. Currently, the materials that can be processed by CAM technology cover various mainstream dental metals, ceramics and composite resins.

[0004] Existing digital denture engraving machines for processing composite resins require the drill bit to be replaced during use. Multiple sets of drill bits are located at one end of the workbench to facilitate the replacement of the drill bits by the engraving components.
