The housing of a grinding spindle unit is pivotably mounted by way of a pivot axle on the receiving part of a grinding machine, e.g., on a grinding headstock. The grinding spindle unit bears a grinding wheel which is driven in rotation. The actuation of an adjusting unit extends a pressure pin, which pivots the housing of the grinding spindle unit about the pivot axle and thus slants the grinding wheel. The pivot axle is in this case formed as a film hinge through a zone of targeted elastic material deformation. A tensile spring device brings about constant contact between the pressure pin and the receiving part.

A jig for supporting a display screen including a platform, a stop and a support is provided. The stop is located on the platform. The support is located at one side of the platform and includes an arcuate surface for supporting the display screen, wherein the display screen is placed on the stop before turning over and is supported by the arcuate surface after turning over. The jig adopts the arcuate surface to contact a surface of a supported object. When turning the supported object over, contact area between the supported object and the arcuate surface can be constantly changed, so that a force exerted on the supported object is even so as to avoid a cracking of the supported object.
