As a metallographist, metallographic sampling is a basic skill, and choosing metallographic equipment and consumables is even more skilled. How to choose a dazzling array of metallographic cutting pieces when sampling during metallographic cutting? Listen to the manufacturer's instructions? Listen to colleagues? Listen to your classmates? Or do you listen to yourself? The answer is, to master relevant knowledge, according to actual needs and technical requirements, it is more appropriate to listen to oneself, and to apply a sentence is" The choice of metallographic cutting pieces by a metallographist should be firmly held in one's own hands&# quo;!

How to choose suitable and high-quality metallographic cutting pieces? The following methods are for reference!


1. Determine the aperture and select according to the type of metallographic cutting machine. Generally, the axial aperture of the metallographic cutting piece matched with the grinding wheel cutting machine is 32mm, and the axial aperture of the metallographic cutting piece matched with the precision cutting machine is 12.7mm.


2. Determine the type and select it according to the material properties of the sample to be cut. Generally, various steels, alloys, Ferrous metals, nonferrous metals, etc. should use the grinding wheel metallographic cutting blade or ultra-thin grinding wheel cutting blade; Diamond metallographic cutting pieces should be used for various composite materials, plastics, rubber, glass, ceramics, etc.


3. Determine the size and select according to the size of the sample to be cut and the required accuracy. If the sample to be cut is small and requires high accuracy, choose a metallographic cutting piece with a small outer circle size and thin thickness; On the contrary, larger sizes can be chosen. Please refer to the manufacturer's technical manual for details.

4. Determine suppliers, and select suppliers with reliable and stable product quality, timely delivery, reasonable prices, and good pre-sales and after-sales service while meeting technical requirements.


In short, by continuously learning and accumulating relevant knowledge and experience in work, mastering the methods of selecting metallographic cutting pieces, and considering multiple dimensions based on actual work situations, we will definitely select good cutting pieces that are easy to use, durable, high-quality, and affordable.

In fact, choosing a metallographic cutting piece is very simple. As long as the type, aperture, outer diameter, and thickness are determined, and then based on the material classification of the sample, the model can be directly determined, and then enter the purchasing process.


By mastering these methods, the metallographist has firmly grasped the selection of metallographic cutting pieces in their own hands, laying a solid foundation for improving work quality and efficiency!
