The Guidance to Select Metallographic Cutters

For metallographic observation, cutting is an essential step. There are many cutting methods, including cutting with machine tools, using industrial cutting machines, and using hand tools.

In the end, the metallographic test is often inaccurate due to the large deformation layer and severe burns on the cutting surface, which affects the evaluation of the metallographic structure. The heat treatment process and the accuracy of failure analysis results.

If you want to obtain high-quality metallographic analysis surfaces, a professional metallographic cutting machine is essential. So, how to choose a metallographic cutting machine to obtain the ideal metallographic cutting effect?

1, The cutting surface of the sample should be smooth and flat. And the perpendicularity between the cutting plane and the longitudinal axis should be as high as possible. Provides excellent surface flatness for subsequent sample preparation.

2, The application range of grinding wheels for metallographic cutting machines is wider. It can be adapted to the cutting of soft metals and other materials, as well as the cutting of harder metals or brittle materials. These require high-quality and different types of ultra-thin metallographic cutting discs.

The metallographic cutting machine has relatively high requirements for its operational stability, positioning accuracy, feed amount, and rotational speed adjustment and control functions. Only the overall performance of the equipment is relatively strong to meet these requirements.

3, The metallographic cutting machine should be simple to operate. It has the ability to accurately position the sample size and precision cutting.

4, There is no overburning phenomenon on the cut surface of the sample. During the cutting process of the metallographic cutting machine, the temperature needs to be lower than 150 degrees Celsius. Of course, the lower the temperature, the better, so as to ensure that the surface of the sample will not be burned.
