Made of solid carbide, the end mills in these sets are harder, stronger, and more wear resistant than high-speed steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. They have a square end for milling square slots, pockets, and edges.

OBTENER PRECIO >>Roll hardness is one of the most important parameters when deciding whether a paper roll is good or bad. A roll that is wound too softly can go out of round when handled. A roll that is wound too hard, on the other hand, can crack during transportation. These variations are difficult to detect. Above all, it is typically the variation in hardness across a given roll that relates most directly ...

OBTENER PRECIO >>The hardness of steel is important to many processes. Steel hardness describes the properties of steel that enable it to resist plastic deformation, indentation, penetration, and scratching. In engineering, steel hardness is important because the inherent resistance of the surface to withstand friction or erosion by oil, steam, and water, typically increases with the relative hardness of steel.

Geschichte. Die Skala wurde von Albert Ferdinand Shore definiert, der in den 1920er Jahren eine Vorrichtung zur Messung der Härte definierte. Der Shore-Durometer war weder der erste Härtetester noch der erste, welcher Durometer (duro-und -meter) genannt wurde.Dennoch ist heutzutage bei einem Durometer üblicherweise die Shorehärte gemeint.
