A surface plate is a solid, flat plate used as the main horizontal reference plane for precision inspection, marking out (layout), and tooling setup. The surface plate is often used as the baseline for all measurements to a work piece.

Surface plates are a very common tool in the manufacturing industry and are often permanently attached to robotic-type inspection devices such as a coordinate-measuring machine. Plates are typically square or rectangular

Cast Iron Surface Plates provide a precision reference for spotting, tool making, inspection of parts, checking accuracy of other surfaces and for many types of gauging and marking out operations.
