The surface plates form the foundation of measurement and marking-out in machine shops and quality control laboratories. They provide a reference surface with absolute flatness, enabling precise alignment of components and the performance of measurements with tools such as dial indicators and height micrometers.
Materials: They are mainly made from natural granite, which offers stability and corrosion resistance, or from cast iron.
Applications: They are used for tolerance inspection, assembly of precision components, and as a base for measuring instruments.
Features: They are classified into accuracy grades (Grade 0, 1, 2) and have excellent hardness to prevent deformation from use.
