Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and more specifically, to metallographic clamps. Background Technology

[0002] The time-consuming steps in metallographic sample preparation are mounting and grinding, and the mounting materials required are quite expensive. Mounting is mainly to avoid the sample being too short to handle and to prevent uneven grinding from affecting the observation of metallographic microstructure. If the sample is easy to handle and the grinding is smooth, the mounting step can be completely omitted. This not only improves the efficiency of metallographic sample preparation but also reduces the cost.

[0003] The existing patent with patent number CN214292623U discloses a metallographic grinding sample fixture, which has a simple structure and is easy to operate. It can solve the problems of sample being difficult to handle and uneven grinding during metallographic sample preparation, eliminate the sample mounting step, improve the efficiency of metallographic sample preparation and reduce the cost of metallographic sample preparation. However, this patent uses a magnet to hold the metallographic sample block, which will lead to unstable fixation during grinding, which may cause the metallographic sample block to shake inside the fixture. Moreover, this fixing method is not suitable for some materials.

[0004] In view of this, we have studied and improved the existing problems and provided metallographic fixtures, aiming to solve the problems and improve the practical value through this technology. Utility Model Content
