For the continuous measurement of the thrust forces produced by the spinning rolls on the workpiece to be extended while the spinning rolls are rotating a measuring rod is provided, which has its one end fixed coaxially on the spindle within a hollow spindle, while its other end projects freely out of the spindle. In the plane of the free end of the measuring rod a distance sensor is arranged, which detects the radial displacement, caused by the radial flexure motion of the spindle, of the measuring rod and computes the force acting on the spinning roll using a processing unit.

Device for measuring forces in metal spinning lathes

In the case of a method and an apparatus for producing parts with high quality surfaces using a mold and curing resin, such as epoxy resin, the first step is to place a workpiece blank so that there is minimum gap between it and the mold. Then resin is introduced into the gap in a non-separating flow utilizing capillary forces in the gap. The epoxy resin then cures and the workpiece coated with such epoxy resin is separated from the mold.

Method for producing components with accurate surfaces

A high-speed rotor constructed of elemental boron and fashioned as a hollow element such as a centrifugal drum.
