måleblokke

Måleblokke, often translated as gauge blocks or slip gauges, are precision length standards used as fundamental reference artifacts in metrology. They are typically made of hardened steel or carbide and are manufactured to extremely high tolerances for flatness, parallelism, and dimensional accuracy. Måleblokke are produced in sets containing a variety of sizes, allowing for a wide range of precise measurements to be assembled through wringing. Wringing is a process where the surfaces of two or more måleblokke are brought into close contact, creating a molecular bond that holds them together without any adhesive. This ability to combine blocks enables the creation of almost any desired dimension within the range of the set, making them incredibly versatile. Their primary use is in calibration laboratories and workshops to calibrate measuring instruments such as micrometers, calipers, and coordinate measuring machines (CMMs). They are also used in precision manufacturing for setting and verifying tool positions. The accuracy of måleblokke is critical for ensuring the interchangeability and quality of manufactured parts. They are classified into different accuracy grades, with higher grades reserved for calibration standards and lower grades for workshop use. Proper handling and maintenance are essential to preserve the accuracy of måleblokke, as they are susceptible to wear, corrosion, and temperature fluctuations.
