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.

Company information
Accurate offers a wide range of products including compression springs, extension springs, torsion springs, wire forming, battery springs, and flat springs in the Ultra Spring (Accurate Original standard spring) series, as well as custom-made items and both wire and sheet materials. We are capable of manufacturing and selling these products. Additionally, we have permanent showrooms for springs in Akihabara, Nagoya, and Kyoto. We maintain a constant stock of catalog items, including Ultra Springs, enabling immediate delivery. Currently, Ultra Springs has approximately 3,000 different items, all with manufacturing lot numbers for traceability, and we promote the industry's first two-point load management and no discontinued items, striving for quality and supply stability to expand globally. Our free spring selection and design software, "Select Spring-kun," allows for easy selection of Ultra Springs, spring design, lifespan calculations, estimates, and delivery date confirmations. The Accurate Tangless Insert reduces the work time of conventional products (Heli-Coil) to one-sixth, and is a NAS-certified revolutionary product that achieves cost reduction for screw hole operations in aluminum cutting and resin materials, particularly in the aerospace and aviation industries, as well as high-speed rail and semiconductor manufacturing equipment, and medical devices.
