一前言近年来,国外在金相试样自动加工技术方面发展迅速,新型高效率的自动金相磨抛光机不断出现。在国内亦引起同行的重视。己研制出若干新颖的金相制样设备。最近我们研制了一种新型的自动金相研磨抛光机,其性能已达到国外同类机型的先进水平。该机能在较短的时间内完成金相试样的粗磨、精磨、粗抛或精抛等多种工序,能自动操作和手工操作,能根据试样的软硬程度选择压力和加工时间,能一次加工3～12块各种形状和尺寸而又未经镶嵌的金相试样,还能加工直径在30～120mm以内的单块试样。基本满足各类金相实验室自动制备金相试样的要求。本文主要介绍该机的原理、结构、性能及其应用。 A foreword In recent years, foreign countries in the metallographic sample processing technology has developed rapidly, a new type of high efficiency automatic metallographic grinding machine continue to appear. In the country also attracted the attention of peers. Has developed a number of new metallographic sample preparation equipment. Recently, we developed a new type of automatic metallographic grinding and polishing machine, its performance has reached the advanced level of similar foreign models. The machine can finish the metallographic sample rough grinding, fine grinding, rough polishing or fine polishing and other processes in a relatively short period of time, can operate automatically and manually, and can select the pressure and processing time according to the hardness of the sample , Can process 3 to 12 pieces of various shapes and sizes without the mosaic of the metallographic sample, but also processing a single sample diameter within 30 ~ 120mm. Basically meet all kinds of metallographic laboratory metallographic sample preparation requirements. This paper introduces the principle of the aircraft, structure, performance and its application.
