摘要
目的 :设计并开发一种适用于义齿研磨、抛光的自动研磨机 ,以代替传统的手工方法。方法 :将两个六角形的研磨桶对称地连于圆形底盘上 ,通过自转和公转运动 ,利用离心力使研磨桶中的义齿与磨料和研磨液相互摩擦 ,达到研磨、抛光目的。结果 :采用不同转速和磨料 ,利用义齿自动研磨机对纯钛义齿部件进行自动研磨 ,使纯钛部件的表面粗糙度Ra值从 1.0 60 μm降至 0 .3 113 μm ,达到临床标准。 结论
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 μm to 0.3113 μm 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.
