Metallographic test sample preparation instrument

Abstract

The invention discloses a metallographic test sample preparation instrument which comprises a stander, a metallographic test sample clamping mechanism, a five-degree-of-freedom driving mechanism, a grinding mechanism, a polishing mechanism and a test sample corrosion structural block. The five-degree-of-freedom driving mechanism is matched with the metallographic test sample clamping mechanism, so that a moving trace of a metallographic test sample in a preparation process can be precisely controlled, and high-quality preparation of the metallographic test sample can be finished by assisting of the grinding mechanism, the polishing mechanism and the test sample corrosion structural block; the polishing, grinding and corrosion processes of the test sample can be automatically controlled; the labor and the time are greatly saved; meanwhile, the test sample preparation defects caused by mistakes or insufficient experience of a technician are avoided. Furthermore, the metallographic test sample preparation instrument has the advantages of small occupation space, high equipment utilization rate, low noise, no pollution, convenience in metallographic sand paper replacement, recycling of polishing liquid, compact structure, low manufacturing cost, convenience in mounting and maintenance and the like.

Description

technical field [0001] The invention relates to a metallographic sample preparation instrument. Background technique [0002] Metallographic sample preparation is an important part of metallographic research, and its process includes mounting, grinding, polishing and corrosion. At present, there are fully automatic inlaying machines on the market, which can complete the automation process of the above-mentioned inlaying operations. However, the grinding, polishing and etching processes are still all manual operations. For the traditional preparation process of metallographic samples, the specific applications and methods are as follows: [0003] (1) Mosaic: Mosaic is suitable for tiny metallographic samples that are not shaped and not easy to handle, and wires, small pipes, thin plates, hammered pieces, etc. are pressed into regular sizes through thermosetting plastics (such as powdered phenolic resin) The cylinder is convenient for grinding or subsequent experiments, such...

Problems solved by technology

[0015] According to the above procedures, the traditional metallographic sample preparation process has the following deficiencies: (1), the preparation steps of the metallographic sample are cumbersome, the preparation cycle is long, and most of the preparation process needs to be labor-intensive; (2), for the experiment The staff has certain technical and experience requirements, which makes the preparation of metallographic samples difficult.

(3) In most cases, artificial metallographic samples often have defects such as uneven surface or residual scratches, and it is difficult to focus under the microscope. If you are not careful or make mistakes, it will often lead to tissue artifacts, thus obtaining wrong conclusion
