APPARATUS FOR FOLLOWING A PREVIOUSLY SHAPED SURFACE OF A WORKPIECE AND FOR REMOVING STOCK SUCH SURFACE WITHOUT SIGNIFICANTLY CHANGING THE SHAPE THEREOF

摘要

The disclosure includes descriptions of a machine for bringing a grinding wheel into precise engagement with a surface of a workpiece. The grinding wheel is resiliently mounted relative to a rotatable spindle to permit limited angular displacement of its axis relative to its axis of rotation, and the workpiece is resiliently mounted relative to supporting structure so as to permit limited radial movement of the workpiece relative to the grinding wheel. This arrangement allows the grinding wheel and workpiece to precisely adjust their positions, in response to forces imparted to them by contact with a previously shaped surface of the workpiece.
