Abstract: For the manufacture of shaped parts (6) from ceramics, for example for dental-technical purposes, first of all a powdery ceramic raw material is compressed to form a ceramic green compact (4). The inner contour and/or the outer contour of the shaped parts (6) is then prepared by machining the ceramic green compact (4) by means of eroding methods, with the ceramic green compact (4) being embedded into a workpiece receiver (1) before the Machining by means of an embedding mass (3) which neither damages nor reacts chemically with the ceramic green compact (4). Subsequently, the machined ceramic green compact (4) is sintered to form a high-strength ceramic shaped part. A ceramic material which is almost shrinkage-free during sintering is preferably used.

The horizontally reciprocable holders facilitate that the mostly different kinds of implements which are positioned in the holder can be brought into a suitable nearness for gripping at the working location of the dental technician, and pursuant to need; for instance, for the creation of the free space which is necessary for carrying out any such work which is to be done without the above-mentioned implements, can be again moved away from proximity to the gripping location.

Abstract: A work position or station including a suctioning device incorporating a suctioning opening for the aspiration of suctionable material which is produced during the processing of workpieces, and a protective plate which guides the suctionable material into the suctioning opening. The protective plate concurrently screens the working personnel carrying out the processing, in particular the head of the person, against the incident suctionable material. The protective plate which is carried by a special mounting support can be moved upwardly prior to the implementing of work without the formation of suctionable material, upwardly away from the suctioning opening in a simple manner into a non-hindering inoperative position.
