To ensure that a collision between the touch probe and workpiece or chuck does not lead to a machine standstill, HEIDENHAIN now offers the TS 642 universal replacement for the touch probes of the TS 6xx series. If the collision happens with one of the TS 640, TS 641, TS 649 or TS 632 touch probes, the TS 642 is available as a universal replacement. This reduces the need for users stocking spare parts. Furthermore, the original transceiver can remain in the machine and all the original cables can also be used. Even the styluses are compatible.
