EQUIPMENT AND OPTIONS IN-PROCESS MEASURING SYSTEM CONTROL SYSTEM A digital measuring head measures the bearing diameter and the concentricity in the process. The control system logs the measured values, calculates the correction data and compensates process influences due to temperature fluctuations or grinding wheel wear. The Erwin Junker Operator Panel was specifically developed to control grinding machines. All machine components are controlled using the operator panel – irrespective of the series and the used control system. The identical structure, intuitive menu guidance and visualization...
