A method for recording the removal of material during high precision finishing work pieces that must be of an extremely precise shape and must withstand extreme stress, as required especially in the aviation industry, is provided which ensures that the work piece has a hardened layer of a required minimum thickness at all stressed or load-carrying positions.

A grinding wheel for producing internal profilings is provided. A grinding disk is disposed at the front end of a rod-like grinding machine arm at the respective angle of slope of the internal profiling that is to be produced. The grinding disk is adapted to be driven by a drive shaft, which is disposed at the other end of the arm, via a drive that extends through the arm. In order, with a simple construction and the use of a disk having a profile that corresponds to the internal profiling that is to be produced, to make it possible to set the grinding disk to the respective angle of slope of the internal profiling that is to be produced, the drive includes a belt that is disposed in the arm and that via respective belt pulleys connects the drive shaft with an intermediate shaft mounted in the front end of the arm. The grinding disk is disposed on a spindle that can be driven by the intermediate shaft via a pair of gear wheels and that, via its bearings, is mounted on the arm in such a way as to be pivotable about the center point of the gear wheel that is disposed on the intermediate shaft.

Grinding wheel for producing internal profilings

A method and device for fine profiling or shaping tools coated with super-hard material, for example cubic crystalline boron nitride or diamond, especially tools coated with a single layer and having a prescribed or predetermined profile or shape. The rotatably driven tool is profiled or shaped in the region of the cutting surface by a clustered electron or laser beam which is controlled in a course corresponding to the prescribed shape or contour of the tool, and is oriented tangential to the tool; the profiling is accomplished by vaporization of the crystal tips or points which project from the desired profile. The cutting surface may be roughened in conformity to the desired profile after the fine profiling or shaping thereof. The rotatably drivable tool, and the device which produces the electron or laser beam, are mounted in such a way that a relative movement can be carried out along a prescribed path or course between the tool and the electron or laser beam, which is oriented tangential to the tool.

An apparatus for grinding of internal, axially extending profiles, particularly for flanks on spline bore hub profiles and inner toothing, and driven by an electric motor, comprising a grinding arm of mandrel shape having a grinding wheel mounted on both sides therein, a toothed belt completely disposed inside of and running in the grinding arm operatively driving the grinding wheel. Gear wheels and the toothed belt thereabout are disposed in a channel formed in the grinding arm. An encapsulating shield completely encapsulates the grinding arm, the mounting for the grinding wheel, the toothed belt and the gear wheels. The channel constitutes a feed for oiled pressurized air to the mounting for the grinding wheel, and the grinding arm is formed with at least one separate grinding-oil channel adjacent the first mentioned channel for feeding grinding-oil to outside of the encapsulating shield adjacent the grinding wheel.
