Abstract
Polishing machine is a kind of precision and ultraprecision machining method. It refers to the use of tools by abrasive on the surface of a workpiece, process, micro machining. Characteristics of polishing machining is machining accuracy and high quality. Therefore, the polishing machine is the important condition to guarantee the polishing machine, so people devoted to the study of the different polishing machine. The current domestic production of high speed polishing machine manufacturers a lot, but due to the polishing machine targeted, for different workpiece, method of polishing machine to also have very big difference.Ring polishing machine is a special machine tool precision machining parts, the machine can process parts. In order to improve the overall quality of processing, based on in-depth analysis of the original machine, developed the ring parts finishing machine is a new type of high precision. The machine control lapping tool movement through the two parts of the power source. On the whole transmission system is analyzed, the design of the transmission gear. In the design of the base of each part of the general structure of the arrangement. The new machine overcomes some shortcomings of the original machine, successfully improve transmission efficiency and precision. This design is helpful to improve the production efficiency in the original foundation. The characteristic of the machine: high precision processing technology, stable performance, high productivity.
