Außenmessbacken

Außenmessbacken, often translated as external measuring jaws or outside jaws, are a crucial component in various measuring instruments and machine tool accessories. Their primary function is to provide a defined surface for measuring the external dimensions of an object. In the context of measuring tools like calipers or micrometers, these jaws are designed to precisely grip or contact the outer surfaces of a workpiece to determine its diameter, length, or width. The accuracy of the measurement directly depends on the precision and condition of the measuring jaws.

In machining, Außenmessbacken are also found on chucks, particularly on lathes. Here, they serve to hold and rotate a workpiece. These chuck jaws come in various configurations, such as two-jaw, three-jaw, or four-jaw chucks, each offering different holding capabilities and suitability for various shapes and sizes of workpieces. The design and material of these chuck jaws are critical for ensuring a secure grip without damaging the workpiece, while also allowing for accurate machining operations. They can be solid or reversible, allowing for the measurement or clamping of both large and small external diameters. The proper calibration and maintenance of Außenmessbacken are essential for achieving reliable and accurate results in both measurement and manufacturing processes.
