Mõõtekeermega

Mõõtekeermega, often translated as "measuring thread" or "measuring screw thread," refers to a specialized type of thread used in metrology and precision engineering. Unlike standard fastening threads, the primary purpose of a mõõtekeermega is to enable highly accurate measurements of dimensions, distances, or mechanical properties. These threads are designed with exceptionally tight tolerances and often exhibit specific geometric profiles that facilitate precise interaction with measuring instruments or other components.

The design of a mõõtekeermega prioritizes uniformity, repeatability, and minimal play. This can be achieved through various methods, including grinding, lapping, or specialized thread rolling processes. The materials used for mõõtekeermega are typically hard and wear-resistant, such as hardened steel or specialized alloys, to maintain their accuracy over time and repeated use. Applications include precision lead screws in machine tools, calibration standards, components in scientific instruments, and high-accuracy positioning systems. The specific thread form, pitch, and diameter are critical and are defined by relevant metrology standards to ensure interchangeability and comparability of measurements. The concept extends beyond simple linear measurement, sometimes being employed in torque measurement or force sensing applications where the deformation or interaction of the thread under load provides a measurable output.
