Mittauspintoja

Mittauspintoja refers to measuring surfaces in Finnish. These are precisely manufactured surfaces used as reference standards or workpieces in various metrology and engineering applications. Their primary function is to provide a highly accurate and stable baseline against which other dimensions or shapes can be compared.

The materials used for measuring surfaces vary depending on the application, but common choices include hardened steel, granite, and ceramics. These materials are selected for their hardness, stability, low thermal expansion, and resistance to wear and corrosion. The manufacturing process for measuring surfaces is critical, involving techniques like grinding, lapping, and polishing to achieve the required flatness, straightness, parallelism, and surface finish.

Measuring surfaces are essential for calibration and inspection activities. They are used in coordinate measuring machines (CMMs), optical comparators, surface plates, and other precision measuring instruments. In manufacturing, they serve as masters for setting up machinery, checking tool wear, and verifying the accuracy of manufactured parts. The quality and accuracy of a measuring surface directly impact the reliability of all subsequent measurements. Regular maintenance and care, such as cleaning and avoiding damage, are crucial to preserving the integrity of these critical metrological tools.
