Description

Technical Field

[0001] The utility model belongs to the technical field of artificial teeth carving, in particular to a artificial teeth carving machine with cooling function. Background Art

[0002] Dentures are artificial devices used to replace missing natural teeth. When teeth are lost due to various reasons, dentures can help restore chewing function, improve pronunciation, and maintain facial appearance and beauty. Dentures can be designed and made of different materials to adapt to the oral conditions and needs of different patients. Dentures are mainly made of metal, ceramics, resins and high molecular polymers. When making dentures, a denture engraving machine is usually used.

[0003] A denture engraving machine is a digital device specially used for making dentures. It has the characteristics of high precision and high efficiency. It can quickly and accurately process denture materials into various complex shapes and structures, ensuring that the denture matches the patient's oral cavity and improving the quality and comfort of the denture. At the same time, it also greatly reduces the errors and uncertainties in the traditional manual denture making process. The processing principle is to accurately calculate the tool's motion trajectory and processing parameters through the control system based on the denture model generated by the design software. Then, the spindle drives the tool to cut, engrave and other operations on the denture material according to the set trajectory and speed, and gradually processes the material into the required denture shape.

[0004] When the existing denture engraving machine is cutting and engraving the denture, the high-speed friction between the drill bit and the material will increase the temperature of the drill bit. If it is not cooled down in time, the drill bit will be damaged, and the high-temperature drill bit will also deteriorate the contact surface of the material, making the manufactured denture unusable; and if the production is stopped to wait for the drill bit to cool down by itself, the time required for the denture production will be extended. Therefore, a denture engraving machine with cooling is proposed to address the above problems. Utility Model Content
