When it comes to metallographic cutting machines, many friends who are new to the metallographic sample making industry are confused. Metallographic cutting machines have both grinding wheel cutting and precision cutting. When do you choose grinding wheel cutting? When to choose precision cutting? How to choose a metallographic cutting machine? I am a bit confused. When I first joined the industry, it was the same. So today, I will sort it out and share it with everyone.

      First of all, let's talk about the respective characteristics and applicability of grinding wheel cutting and precision cutting.

    Compared to precision metallographic cutting machines, grinding wheel metallographic cutting machines have higher power and faster cutting speed, and most use wear type metallographic grinding wheel cutting blades to cut the metallographic specimens. The size of the grinding wheel cutting machine also affects the parameters of the grinding wheel; The increase in diameter of the grinding wheel cutting blade results in a larger sample size that can be cut. But at the same time, the thickness of the grinding wheel also increases. Therefore, grinding wheel metallographic cutting machines are suitable for cutting large-sized, non precision, non brittle and fragile specimens.

    The precision metallographic cutting machine is relatively small compared with the grinding wheel metallographic cutting machine. It is generally a desktop computer, with low cutting speed and slightly lower power. The cutting blades are generally diamond blades, aluminum oxide blades or cubic Boron nitride blades with a diameter of 3in to 8in. The cutting blades are mostly ultra-thin, with relatively small load during the cutting process and small heat and damage depth. Therefore, precision metallographic cutting chambers are more suitable for cutting small, precise, fragile, and superhard metallographic specimens. The width of the incision is small, used for very precise cutting.

      With the above understanding of grinding wheel cutting and precision cutting, I believe you have an answer to which metallographic cutting machine to choose in your laboratory.

    But in reality, for the selection of metallographic cutting machines, this is only a preliminary determination of the cutting method, including whether it is automatic or not, how to configure fixtures, and how to choose the size and model of the cutting blade. It is still necessary to make a detailed selection based on the manufacturer's various product information and recommended solutions. In addition, many factors such as price budget need to be considered.
