A new measuring device from Krauss Maffei is designed to detect wear in the processing section of extruder barrel housing bores by measuring the inside diameter of each bore.

The system, which includes measuring head equipped with an endoscopic camera, uses sensors to measure the actual bore diameter over the entire processing section length. During the measuring process the actual diameter of the bore is measured every 5 mm, and this pro- cedure is carried out three times in different positions in each of the two bores.

The result obtained is a representation of the inside diameter in the form of six tracks (three left, three right) and with an axial resolution of 5 mm. The measuring results and the endoscopic findings are consequently combined to provide a professional report comprising of a graphic representation of the inside diameter, a description of the actual state of the checked barrel with pictures, as well as recommendations as to any further necessary actions.
