Abstract: The invention relates to a device for cooling workpieces. The device has at least one nozzle which is configured to blow a fluid onto a workpiece. At least one surface temperature sensor is able to be arranged on the workpiece. In order to cool the workpiece, it is blown with a fluid by means of the at least one nozzle, the temperature of said fluid being lower than the surface temperature of the workpiece. In the process, the surface temperature is monitored by means of the at least one surface temperature sensor.

Abstract: The invention relates to an intermediate element for the arrangement of a probe pin with respect to the probe pin carrier of a coordinate measuring machine, having a single-piece base body with a probe pin end and a machine end. It is provided here that the machine end is provided with a coupling element and with a means for ensuring a reproducible rotational alignment, and the probe pin end has a bearing face which is inclined in a fixed manner with respect to the axis of the coupling element, is provided on a general ball segment form which is flattened by the bearing face, and is configured with a positively locking means and/or frictional means for the positively locking and/or frictional engagement with a fastening end of the probe pin in contact with the bearing face.

Abstract: The invention relates to a probing means for coordinate measuring machines, with a probe tip having a recess and a shaft penetrating with a shoulder into the recess. According to the invention, the recess tapers towards the interior of the probe tip and the shaft has a construction complementary thereto.

Abstract: The present invention relates to a feeler pin for a coordinate measuring machine. The feeler pin comprises a shaft having a first end and a second end, a fastening sleeve for fastening the feeler pin in a feeler pin holder, and an identification device for identifying the feeler pin. A feeler object is provided at the first end of the shaft, wherein the identification device can be read out via a first contact and a second contact. Further, it is provided that the second end of the shaft and the fastening sleeve are connected by a plastic section, wherein the first contact is provided by the fastening sleeve, and the second contact is provided by a rotationally symmetrical contact device which is electrically insulated from the fastening sleeve by the plastic section. Further, the present invention relates to a feeler head for holding the at least one feeler pin.

Abstract: The invention relates to a feeler (1) having a shaft (2) and a coupling body (3) fixing the latter for coupling to a coordinate measuring device. It is provided here that the shaft is fixed in the receiving body by means of injection molding.
