Monitoring the clamping position of tools

Often, initiators and switching rings, which provide a switching signal, are used to monitor the clamping position in high-performance tool machines. However, these require complex adjustment and set up. Analog sensors from the Micro-Epsilon LVP series offer significant improvements. The cylindrical sensor is integrated into the release device and directly measures the clamping stroke of the drawbar. On the drawbar, a ring is fastened, which acts as the target for the sensor. The LVP sensor can be universally used with the most varied types of tool due to an extremely compact sensor design. The sensor supplies an analog signal according to the stroke motion of the drawbar when clamping the tool. Consequently, continuous monitoring is possible without the switching point having to be laboriously set mechanically. The miniaturized sensor electronic unit can either be accommodated at the point of measurement or in the control cabinet. Thanks to its high accuracy, the LVP sensor contributes significantly to meeting the ever increasing demands on machine tool precision and availability.
