Surface plates and stands are used in precision measurement applications to provide a flat and level surface for accurate measurements. Surface plates are large, flat plates made of materials such as granite, cast iron, or glass. They are typically used as a reference surface for measuring the flatness and straightness of other surfaces or parts.

Surface plate stands are used to support the surface plate and provide a stable base for taking measurements. They can be adjustable in height and can have leveling feet to ensure the surface plate is level. Surface plates and stands are used in a variety of industries, including aerospace, automotive, and manufacturing, for applications such as machine tool setup, metrology, and inspection.

Surface plates are available in various grades of accuracy, ranging from laboratory grade to inspection grade. The grade of the surface plate refers to the degree of flatness and accuracy, with higher grades being more precise. Inspection-grade surface plates are typically used in quality control and metrology applications, where precision and accuracy are critical.

Proper care and maintenance of surface plates is essential to ensure their accuracy and longevity. They should be cleaned regularly with a non-abrasive cleaner and checked for flatness using a precision level. Any damage or wear to the surface plate can affect its accuracy, so it
