The invention relates to a workpiece processing machine (1), and to a method for operation of a workpiece processing machine (1). The workpiece processing machine (1) comprises an automatically adjustable stop finger (17), and has, for monitoring adjustment movements of the stop finger (17), a monitoring device (36, 37, 38) that comprises an illuminating device (36) and at least one optical detection device (37). In operation of the workpiece processing machine (1), during an automatically controlled adjustment movement of the stop finger (17), a light beam (38) is radiated into an area ahead of the stop finger (17) in the adjustment direction. Upon detection of a first light image (43) projected onto an object surface (42) by the first light beam (38), a safety measure is triggered.

The present disclosure provides for a container having an interchangeable liner. The container is comprised of a bottom portion having an aperture to receive the interchangeable liner as well as securing protrusions and stabilizing members. The securing protrusions serve to cooperate with the aperture to lock the liner within the container, whereas the stabilizing members serve to stabilize the container when a substance within the container is being mixed.
