What is gauge blocks?

Gauge blocks, also known as slip gauges or Jo blocks, are precision-ground blocks used for making accurate measurements and calibrating measuring instruments. They are typically made of high-quality steel, carbide, or ceramic materials and come in a variety of sizes and thicknesses.

Gauge blocks are used in combination with a dial indicator or micrometer to measure distances, angles, and parallelism. They are also commonly used in machining and manufacturing industries for setting accurate distances for machinery, setting heights for cutting tools, and calibrating other measuring devices.

One of the key features of gauge blocks is their accuracy and ability to be stacked together to create precise measurements. By combining different gauge blocks with known thicknesses, users can form a variety of different lengths to calibrate instruments or verify the accuracy of a measurement.

Gauge blocks are typically stored in a protective case to prevent damage or wear and tear. They should be handled with care and kept clean and free from debris to maintain their accuracy over time. Regular calibration and inspection of gauge blocks are essential to ensure their continued precision and reliability in measurements.
