Abstract: A device for the exchangeable fastening of a probe pin or probe pin combination (3) on the probe head (1) of a coordinate measuring system is taught where a pneumatically operated clamping device is provided which between the connecting body (9) of the probe pin (3) and the mounting body (4) in the probe head (1) generates a vacuum serving as a holding force. A venting valve (8) and an electrical blocking valve (7) are installed in the vacuum line (5) between a vacuum pump (6) and the probe head (1).

Abstract: A piezo-controlled dynamic probe or feeler head for measuring installations and measuring machine, which is in an operative connection with a measurement evaluating or plotting unit and, selectively with a measuring machine control. The probe is constructed from two mutually independently operating measuring signal generating installations, which are equipped with mutually separate or independent circuits and which act in such a manner on the measuring evaluating or plotting unit and, selectively, on the measuring machine control, that upon the generation of a signal from the first measuring signal generating installation, stored data regarding the position of the probe can be recognized as being valid only at the presence of a confirmation or acknowledging signal from the second measuring signal generating installation.

Abstract: A dynamic contact or feeler head for measuring machines and for the utilization thereof in processing machines for the solution of measurement tasks. The feeler head includes a centrally inserted feeler which is deflectable in at least two coordinate directions, which is constructed so as to be tiltable about a tilting axis which is always equally distant from the feeler and always located in the same plane, and with an electromechanical, inductive or optical signal transmission.

Abstract: A mounting arrangement for the exchangeable attachment of a probe stylus or a probe styli combination on a probe for a coordinate measuring installation. The mounting arrangement is constituted from an electrically-operating clamping device with a permanent magnet and an electromagnet wherein the field from the electromagnet is superimposed on the field from the permanent magnet. A connecting member for the probe stylus or the probe styli combination is drawn through the intermediary of the clamping device against a bearing or support in the mounting member therefore on the probe which determines its position.

Abstract: Multi-coordinate measuring and testing machine which is essentially constituted from a fundamental machine unit, a scanning or sensing system which is movable in at least two coordinate directions, and a machine-controlling unit. The scanning or sensing system is constructed as a multi-sensor system and is constituted from a mechanical sensing head or probe with at least one stylus and/or a video scanner and/or a laser scanner which are controlled from a microprocessor and operate independently of each other, and which are selectively either individually actuatable by means of software connected thereto, or can be coupled to each other in a dual or triple combination.
