Types of spring hardness testing machines, differentiation and precautions during measurement.
[Reproduction of Private Spring Preparatory School Lecture 3] Explanation of the Brinell hardness testing machine! Hard materials are tested with a red signal, and the testing surface is generally flat.
The Katasasa testing machine is primarily differentiated by the size of the spring. ■ Brinell: Used for relatively large items among leaf springs and coil springs. ■ Vickers and Rockwell: Used for medium to small items such as thin plate springs and wire springs, and are also convenient for measuring hardening depth and decarburization depth. ■ Shore: Used for large to medium-sized springs that have been surface-finished, but unlike the previous three, it is characterized by not leaving indentations. Please make sure to use them appropriately, such as not using a deba knife to cut mudfish or a sashimi knife to cut salmon heads. Now, let's focus on the Brinell method among the push-in Katasasa testing machines. If you remember Brinell, Vickers and Rockwell are quite similar, so the points to pay attention to are also similar. *For detailed content of the article, you can view it in the PDF.
