表面粗さ計
あ 表面粗さ計 is a precision instrument that measures the smoothness or roughness of a surface by analyzing its texture profile. It is widely used in industries such as automotive, aerospace, manufacturing, and electronics to ensure components meet quality standards.
Surface roughness testers quantify roughness in microns (µm) or Ra (Roughness Average) values. These instruments assess key parameters such as peak height, valley depth, and spacing between irregularities, helping manufacturers maintain product performance and minimize defects.

サンドブラスト粗さ試験機
の サンドブラスト粗さ試験機 measures the surface roughness after sandblasting or shot peening processes. Sandblasting is used to prepare surfaces by removing rust, paint, and other contaminants, creating an optimal surface texture for painting, coating, or bonding. The roughness created ensures better 接着力 of coatings and paints, making the surface more durable and corrosion-resistant.
