Abstract:
Objective: To develop a new denture grinding machine to replace the manually grinding procedure for metallic denture parts. Methods: Two hexagonal barrels were symmetrically fixed on a round plate. The direction of rotation and revolution of the barrels were reversed. The denture parts that were put into the barrels together with grinding materials and solution were ground by centrifugal force caused by rotation and revolution of the barrels. Results: The surface roughness of pure titanium castings went down from 1.060 ?m to 0.3113 ?m after ground with the automatic grinding machine using different shapes of grinding materials in series. Conclusion: The automatic grinding machine is competent for grinding the metallic denture parts.
