Description

An internal grinding machine for dental molds

Technical field

The utility model relates to the field of denture processing, in particular to an internal grinding machine for dental molds.

Background technique

Dentures, often called false teeth, refer to the general name of restorations used to replace missing natural teeth after the natural teeth of a single jaw, upper and lower jaw, or all dentitions have been extracted or lost. The dental molds need to be polished during the production process to improve the quality of the teeth. Comfort in using dental molds.

After searching, the Chinese patent publication number is CN218964953U, which discloses an environmentally friendly internal grinding machine for dental mold processing. The patent is equipped with a dust cover to cover the inner grinding head and clamping assembly. The X-axis rotating rod and the clamping assembly are operated outside the dust cover. The Y-axis rotating rod allows the internal grinding head to grind the dental mold clamped on the clamping assembly. There is no need to reach into the dust cover to grind the dental mold, which alleviates the dust passing through the opening on the dust cover when the internal grinding machine is working. In addition to the problem of hole leakage, the dust generated by the internal grinding head grinding the dental mold is sucked into the vacuum cleaner through the vacuum tube connected to the dust suction port, thereby realizing dust collection.

However, debris may stick to the inner grinding head during the grinding process, and the inner grinding head is always rotating. The side facing away from the vacuum cleaner cannot be cleaned well, which may affect the quality of later grinding.
