The disclosure relates to a workpiece support for a processing machine for flat workpieces, wherein the workpiece support has support elements forming a plurality of support points for the workpieces which span a workpiece support plane for the flat workpiece, wherein a transfer device for transferring at least one of the support elements from a first position into at least one further position is provided. At least one support element is thus configured to be transferred from the first position into the at least one further position even when a workpiece is loaded, by a movement parallel to the workpiece support plane. The disclosure also relates to a processing machine including such a workpiece support and a method for processing a workpiece.

A substrate container includes a container door, a container shell, and a cassette. The cassette includes slots for accommodating substrates, a handle, and vertical retention features extending above the handle and attached to the cassette. The vertical retention features are configured to contact the container shell when the container is closed around the cassette. The vertical retention features can be configured to deflect when contacting the container shell.

A machine tool for manufacturing flat instruments and/or tools for medical technology, including a machine frame, a working spindle, a workpiece table that can be assigned or is assigned to the working spindle and is mounted directly or indirectly on the machine frame about a table axis, and a workpiece holder which is fixed to the workpiece table and has a first workpiece receptacle to which a flat workpiece can be fixed for machining a flat side, and which has a second workpiece receptacle that runs transversely or obliquely to the first workpiece receptacle and to which a flat workpiece can be fixed for machining an end face. The workpiece table is accessible from a first working position and can be moved by rotating or swivelling about the table axis assigned to it into a second working position.
