Metallographic Microscope Series The structure of optical metallographic microscope generally includes magnification system, optical path system and mechanical system, among which the magnification system is the key part. The preparation process of metallographic samples generally includes five steps: sampling, rough grinding, fine grinding, polishing and etching. The interception of samples from metallic materials and parts to be tested is called "sampling". Selection of sampling sites and grinding surfaces must be based on analysis requirements. The size of the sample is not uniform, from the perspective of easy to hold and grinding, the general diameter or side length of 15~20mm, 12~18mm high is suitable. For those too small, irregular shape and the need to protect the edge of the sample, you can adopt Mosaic or mechanical clamping method. For the inlay of metallographic sample, the appropriate size (about φ L5-20mm) of steel tube, plastic tube or paper shell tube is placed on the smooth plastic (or glass) plate, and the sample is placed in the tube to be ground face downwards into the filler, which can be solidified and hardened for a period of time. 3) Chamfering On the premise of not affecting the purpose of observation, the edges and corners on the sample should be ground off to avoid scratching the sandpaper and polishing fabric. metallurgical analysis,optical microscope for metallurgy,metallurgy microscope TROJAN (Suzhou) Technology Co., Ltd. , https://www.troolymaterial.com
