In most cases, the purpose of metallographic sample preparation is to prepare a flat mirror surface for observation after corrosion or direct observation.


Generally speaking, metallographic preparation involves three steps: cutting, embedding, and polishing. If cutting and inlaying are both early steps in sample preparation and are relatively easy. So grinding and polishing is a relatively important and difficult step in the entire sample preparation process. The results related to the ultimate observation.


In the early days, sample grinding was mainly done by holding the sample with hands, and the mastery of hand force and direction was based on experience, so novice sample making was relatively difficult to control. With the development of equipment technology, semi-automatic and automatic metallographic polishing machines are becoming increasingly popular in scientific research institutions, universities, testing industries, and enterprises.


The gradual transition from manual to automatic metallographic sample preparation is a result of the progress and development of engineering technology and materials science, as well as to adapt to larger scale sample preparation work. By utilizing automation technology and equipment, the chance factors for successful grinding and polishing have significantly decreased, and sample preparation has shifted from relying on humans to relying on equipment. At the same time, it also lowers the technical entry threshold, allowing personnel who have not previously engaged in metallographic preparation work to quickly learn and complete the preparation work.


Nowadays, automatic metallographic polishing machines can preset programs, use fixtures to hold samples, automatically rotate, drip liquid, and adjust the loading force. It basically meets the preparation requirements of common materials. If it is an experienced metallographic preparation personnel, it will open up new sample preparation channels and improve the preparation effect. Only in this way can we meet the increasingly demanding experimental needs.


The above is what Kemai Laboratory Metalworking wants to share with everyone, hoping to help everyone. We also welcome new and old customers with metallographic sample preparation needs and problems to come and communicate and learn together!
