  • Device for microfinishing both sides of a workpiece
    Patent number: 5720652
    Abstract: In a device for microfinishing both sides of disklike workpieces with plane and/or spherical surface, two tool spindles with two tools are provided on two orbit spindles; the two tools engage the two face-end surfaces of the workpiece. The tool spindles revolve, spaced apart by a certain distance, around the axes of the two orbit spindles. In this way, excellent micrographs and excellent grinding results are attained.

  • Super finishing machine
    Patent number: 5695391
    Abstract: In a microfinishing machine for machining cylindrical inner or outer faces of a work piece, a grinding belt is pressed against it with a flexible machining shell. This has the advantage that the shell can move radially in sections and as a result, the grinding belt can press in the shape of a circle against the work piece.

  • Process and apparatus for centerless superfinishing of rollers
    Patent number: 5674112
    Abstract: In a process and an apparatus for centerless superfinishing of rollers with arbitrarily curved jacket faces by means of an oscillatingly driven honing stone, the rollers are transported in the continuous process and the honing stone moves together with the rollers at the same speed or at superimposed speeds. The rollers rotate relative to their associated honing stone as a result of being transported causing machining to occur.
