The performance of a metal depends on its composition and microstructure, among which microstructure has a direct impact on its performance. Therefore, we can predict and judge the performance of the metal by observing and analyzing the microstructure of the metal (i.e. metallographic analysis technology), and analyze the reasons for its failure and failure. Metallographic analysis technology is a routine inspection method for evaluating the internal quality of metal materials based on relevant standards and regulations, and can be used to determine whether the production process of parts is complete, which helps to identify the causes of defects in parts. Therefore, it is an essential means in the production, use, and scientific research of metal materials.


To conduct metallographic analysis, the first step is to prepare samples (i.e. metallographic samples) according to various inspection standards and regulations. If the metallographic samples are not prepared properly, false images may appear, leading to incorrect conclusions. Therefore, the preparation of metallographic samples is very important. Usually, the preparation steps of metallographic specimens mainly include sampling, sample preparation, grinding and polishing, and other processes.

Below we will introduce the important tool used in the first sampling step - the grinding wheel metallographic cutting machine METLAB CUT-10


The METCUT-10 manual grinding wheel cutting machine is an economical and practical manual grinding wheel metallographic cutting machine. The cutting blade has a diameter of 10 inches, a rotating speed of 2865 rpm/min, and a cutting capacity of 90mm. It can complete the metallographic cutting of the vast majority of materials and is a basic model of laboratory equipment.


METCUT-10 has low requirements for the venue and strong adaptability. There are desktop and cabinet types, both equipped with independent water circulation systems to avoid laboratory water supply and drainage renovation.

Of course, in addition to the metallographic cutting machine introduced by the editor today, Nanjing Chain Energy also has different models of metallographic cutting machines such as precision cutting machines, automatic cutting machines, and manual/automatic integrated cutting machines. Welcome to visit our company for inspection and practical operation.
