The rolls are machined automatically using the up-to-date CNC machine tools.
The control programs provide high accuracy of geometry and surface finish of
the rolls being machined. The internal flaws are detected by the ultrasonic flaw detectors of KRAUTKRAMER Company (Germany) and SONATEST Company (England). The surface defects are detected by the dye-penetrant and magnetic powder inspection. Hardness is tested using the Shore scleroscope, model D (USA), EQUOTIP of Proceg Company (Switzerland). |
