The part being measured is inserted between the anvil and the spindle, and the spindle is then moved against the part until it makes contact, providing a precise measurement of the part’s diameter.

Snap gauges are commonly used in the manufacturing of parts and components that require a precise outside diameter, such as shafts, pins, and other cylindrical parts. By using snap gauges, we can ensure that our products meet the required specifications and tolerances, and that they will function properly when assembled into the final product.

Surface plates are large, flat plates made of granite or other high-quality materials used in precision manufacturing for measuring and inspecting parts and components. At Walker Products, we use surface plates to ensure that our products meet the required specifications and tolerances.

Surface plates are typically used in conjunction with height gauges, dial indicators, and other measuring tools to check the flatness, straightness, and overall accuracy of parts and components. They are also used to support large parts during inspection or assembly.

To ensure the accuracy of surface plates, they must be periodically calibrated using a precision instrument such as a laser interferometer. This process ensures that the surface plate is flat and level to within a very high degree of precision, which is necessary to accurately measure the dimensions of parts and components.
