INC 05200 Surface Plate Square

A precision tool designed for use with surface plates for inspection or layout operations and to provide a simple and effective means of obtaining a reference line contacting the work in any plane. It consists of precision ground ends parallel to each other and square with the longitudinal axis. The working surfaces may be continuous or broken by concave divisions equally spaced to develop a narrower working surface.

Additional Information for Surface Plate Square Additional Information for Surface Plate Square

A Surface Plate Square is a precision measuring tool used in the field of metrology and precision engineering. It is classified under the supply class "Inspection Gages And Precision Layout Tools" and belongs to the supply group "Measuring Tools".

A Surface Plate Square consists of a flat, rectangular plate made of high-quality granite or cast iron. The surface of the plate is precision ground and lapped to provide a flat and smooth reference plane. The squareness of the plate is ensured by strict manufacturing standards.

The purpose of a Surface Plate Square is to provide a reliable and accurate reference surface for measuring and inspecting the squareness and flatness of other workpieces or tools. It is commonly used in industries such as manufacturing, machining, and quality control.

To use a Surface Plate Square, the workpiece or tool being inspected is placed on the surface plate, and the squareness or flatness is checked using precision measuring instruments such as dial indicators, height gauges, or surface roughness testers.

Surface Plate Squares are essential tools in ensuring the accuracy and precision of various manufacturing processes. They are commonly used in conjunction with other measuring tools and instruments to ensure the quality and precision of machined parts, assemblies, and tooling.

It is important to handle and store Surface Plate Squares with care to prevent any damage or wear that could affect their accuracy. Regular cleaning and maintenance are also necessary to keep the surface plate in optimal condition.

Overall, Surface Plate Squares are indispensable tools in the field of metrology and precision engineering, providing a reliable reference surface for accurate measurements and inspections.
