The laboratory where I work mainly conducts metallographic testing of low-carbon steel. Every day, samples are prepared for a batch of low-carbon steel submitted by customers for inspection. The first step of metallographic testing is cutting and sampling. Therefore, there are considerable requirements for the cutting ability and quality of metallographic cutting machines. A metallographic cutting machine that can quickly and high-quality cut low-carbon steel is the cutting machine that meets the technical requirements.


After thousands of choices, we finally purchased a desktop manual grinding wheel metallographic cutting machine METCUT-10 from Kemai Testing Nanjing Company from MetLab in the United States.

Before purchasing, through thorough communication, the engineer of Kemai Testing recommended this model based on the specific needs of our laboratory, and selected fixtures, metallographic cutting pieces, coolant and other configurations according to the application. A complete solution that meets the application requirements was recommended to us. We were invited to take samples to the laboratory of Kemai Testing Company for on-site testing, and experienced the low-carbon steel cutting solution recommended by the engineer, The conclusion is that not only is the plan completely feasible, but the price of this metallographic cutting machine is also impressive.


Calmly, we have also compared and evaluated several other imported similar equipment, and the conclusion is that pulse detection is feasible; MetLab's Desktop Manual Grinding Wheel Metallographic Cutting Machine METCUT-10 Low Carbon Steel Cutting Plan” It's more suitable for us, so we ordered this equipment.

This manual grinding wheel metallographic cutting machine is very simple to operate and has high safety. The 50L three-level filtration cooling circulation system has a good cooling effect, and the cut sample has a flat and smooth cross-section without burns. The application of ultra-thin metallographic cutting sheets results in very narrow incisions and accurate size control. Manual cutting is very flexible and has strong cutting ability. Regardless of the sample size, size, length, length, thickness, or fineness, it can be easily cut, which is indeed very useful.


We use a randomly matched QMAXIS grinding wheel cutting blade with a diameter of 10 inches and a hardness of HRC30-45. The microstructure under the microscope after sample preparation is shown in the following figure:

The above figure shows the microstructure of AISI 1020 low-carbon steel, which was etched with 2% Nital (nitric acid alcohol solution) and magnified 80 times under a microscope. Ferrite, pearlite, and visible grain boundaries are clearly visible. Choose from a thousand options, and use this metallographic cutting machine for cutting low-carbon steel samples, which is very easy to use!
