Position measurement in the zero point clamping system
In modern machine tools, zero point clamping systems ensure reproducible positioning of the workpieces, clamping stations and workpiece carriers. Magneto-inductive displacement sensors from Micro-Epsilon measure the position of the clamping cylinder in which the workpiece carriers are locked. Inserting the clamping bolt into the cylinder changes the position of the locking unit. A magnet attached to the lock acts as a measurement object for the sensor. The sensor permanently measures the magnet’s movement and transmits this to the control system. Magneto-inductive sensors from Micro-Epsilon are available in miniature size or as a PCB solution for high quantities. Particularly in serial applications, the mainSENSOR series impresses with an excellent price/performance ratio.
