2018 has already passed half unconsciously, fortunately, a small wish at the beginning of the year&# 8217& Flash& Ldquo; Buy a metallographic cutting machine with good quality& Rdquo; Finally, after more than half a year of consultation, investigation, application, and bidding, the dust has finally settled today. We have obtained an original imported metallographic cutting machine that has been admired for a long time at Chain Energy Metallography Home. Thanks to the patient and professional services of our engineers, we can purchase a set of metallographic cutting machines with good quality and reasonable matching plans based on actual needs and applications.


Over the past six months, I have had multiple contact and communication with engineers from Chain Energy, and I have learned a lot myself. Among them, I have benefited greatly from how to evaluate the quality of a metallographic cutting machine. I can't help but summarize and organize it to share with my friends.


Whether domestically produced or imported metallographic cutting machines, they are mainly used for cutting and sampling metallographic samples, in order to easily obtain qualified or even high-quality metallographic analysis surfaces in the subsequent sample preparation process. The quality of the metallographic cutting machine is directly related to the accuracy of metallographic testing, and affects the accuracy of metallographic structure evaluation, heat treatment process, and failure analysis results. Therefore, during the cutting process of the sample, it is necessary to ensure that the metallographic structure of the sample is not damaged or destroyed as much as possible, and is consistent with the true structure of the component. This requires that the friction heat generated by the rotation of the saw blade and the impact force of the saw blade on the cutting surface be as small as possible when the sample is cut. So the size of the deformation layer on the sample cutting surface and whether there are burns are the standards for measuring the quality of the metallographic cutting machine.

    To summarize, the quality of the metallographic cutting machine is considered qualified if the cutting surface of the metallographic sample has the following characteristics:


Firstly, there is no overburning on the cutting surface of the sample. The metallographic cutting machine is required to have a temperature below 150 degrees Celsius during the cutting process. Of course, the lower the temperature, the better, which can ensure that the surface of the sample does not burn.


Secondly, the cutting surface of the sample should be smooth and flat, and the perpendicularity of the cutting plane and longitudinal axis should be as high as possible. Provide high-quality surface smoothness for subsequent sample preparation.


Thirdly, the grinding wheel application range of metallographic cutting machines should be relatively wide, which can adapt to the cutting of soft metals and other materials, as well as the cutting of harder metals or brittle materials. All of these require high-quality and different types of ultra-thin metallographic cutting blades to be provided. There are high requirements for the stability, positioning accuracy, feed rate, and speed adjustment control functions of the metallographic cutting machine. Only when the overall performance of the equipment is relatively strong can it meet these requirements.


Fourthly, the sample cutting size should be appropriate and accurate. On the one hand, it depends on the experience and work habits of the operator, and on the other hand, it requires the operation of the metallographic cutting machine to be simple, with the ability to accurately locate the sample size and perform precision cutting.

    The above are the basic requirements for the quality of metallographic cutting machines. If the samples cut cannot meet the above four points, then this metallographic cutting machine must not be selected, it really cannot!


A high-quality metallographic cutting machine must first meet the four basic requirements for the samples it cuts. If better performance can be achieved on this basis, it is considered a high-quality metallographic cutting machine. In addition, the appearance of the equipment is beautiful, the structure is sturdy and durable, the manufacturing process is excellent, and factors such as low failure rate are also considered.


If you don't want to spend time and effort consulting and researching one by one, you can tell the engineers of Chain Metallography about your needs and application characteristics. They are both professional and practical, and can tailor a set of reasonable and cost-effective solutions for you. Not only can they meet all application needs, but they can also provide a complete set of high-quality after-sales service. Buying a device allows you to enjoy the professional services of the entire team of Chain Energy, just one word" Value”. Of course, words are baseless, and only practice is the only criterion for testing truth. How can you know without trying.
