Edge processing: Round (circular/square), edge grinding [Special Metal Excel]
You can use it for applications that utilize the material width as is by performing "mimisuri" for burr removal and "round processing" to grind the edges.
Edge processing refers to further processing of the standard slit edge to remove burrs, allowing for delivery in forms such as "mimisuri" (burr removal with a file) and "rounded edge" (where the edges are rounded). This processing enables the use of the material width and edge surface as they are for various applications. Additionally, by smoothing the edge surface, it can prevent fatigue failure from the width direction, leading to improved durability of springs.
