Pintalevyjä

Pintalevyjä, often translated as "surface plates" or "surface tables," are precision measuring tools used in metrology and manufacturing. They are characterized by their extremely flat and smooth upper surface, which serves as a reference plane for accurate measurements. These plates are typically made from hard, wear-resistant materials such as granite, cast iron, or ceramics. The flatness of a pintalevy is critical and is maintained through meticulous manufacturing processes and regular calibration. The quality and accuracy of a pintalevy are usually specified by its flatness tolerance, often measured in micrometers per meter. They are fundamental for tasks like aligning machine components, inspecting the flatness of other parts, and setting up gauges and measuring instruments. The absence of any features or markings on the surface ensures an unobstructed reference for precise dimensional control. Pintalevyjä are essential in quality control departments and precision machining environments to ensure the accuracy and interchangeability of manufactured parts.
