It is to reduce the surface roughness and make them smooth and shiny. It is a very important and necessary step in the metallographic observation and experiment process, and in metallurgy, metal heat treatment has the important meaning. To gain a good metallographic observing effect of polishing quality request is higher, but now the most use of polishing machine kinds are small which used in the laboratory. Polishing section is smaller, polishing quality is poorer, can’t meet the demand of large cross-section polishing. In order to improve the study quality of the casting, use high multiples and middle multiples are must, so we need to design a series of polishing machine meet polishing quality requirements. This subject is based on grinding machine working principle to design a suitable for polishing larger section vertical polishing machine. This paper introduces the application of polishing machine, characteristics, principle and development prospect. At first the design are compared to choice the best one. Among them for spindle and polishing wheel connection, the drive and transmission of workbench scheme selection are designed, and comparison, selection, also introduced the parts in the cabinet arrangement layout. The article on the transmission system, component design choice and the check detailed descriptions and calculation, to ensure the machine can work normally. The last of cooling system are introduced in brief and design. Key words: polishing; vertical polishing machine; project design; design and check; cooling system. 目录 摘要 I Abstract II 目录 1 第1章 绪论 4 1.1 抛光及抛光机的概述 4 1.2抛光机的工作原理
