Electronic end position detectionThe electronic sensor of end position is an equipment for workpiece stops on CNC-machining centres. These stops consist of mostly cylinders, which will be pneumatically extended and retracted before the processing. If a stop is staying accidentally or because of a malfunction in the extended condition, a collision between the milling tool during the workpiece processing is highly possible, as the stops are located at the outside contour of the workpiece. The sensing of end positions consists of a sensor in each single stop. The program start will first be released, when all sensors report that the stop cylinders are retracted again and thus a collision can be ruled out. |
