Abstract A device for adjusting the position of a diamond point in an apparatus for shaping a grinding-wheel. A holder for the diamond point is slidably mounted in an arm which is rotatably mounted about a working axis. The working axis intersects the axis of the path of travel of the diamond point. The device itself comprises a comparator including a probe retractably mounted on the apparatus. The probe is adapted to be brought into position along the axis of the path of travel of the diamond point. To check the position of the diamond point, the latter is removed from the holder and a measuring rod having a spherical end portion of predetermined diameter is substituted in its place. The coincidence of the center of the spherical portion along the working axis is checked on the dial of the comparator. The holder for the diamond point then put back in the arm and brought into position in contact with the probe ; a particular value on the dial of the comparator indicates that the diamond point is on the working axis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
170 words
In an apparatus for the dressing of a grinding wheel comprising a sleeve support for a diamond-holder, said support being rotatably mounted around an axis and being slidable along two perpendicular directions, with means for marking and controlling the rotational displacement around said axis and the movement along said two directions, the improvement comprising: one arm of adjustable length pivotingly mounted on said support around an axis perpendicular to said axis of rotation, a comparator secured at one end of a bracket a branch of which is slidably mounted at the end of said arm opposed to the one attached to the support, and means for adjusting the length of the arm and for positioning the bracket to bring the sensing finger of said comparator in alignment with the longitudinal axis of said sleeve in which a measuring-rod may be mounted adapted to cooperate with said sensing finger whereby the diamond tip is exactly located on said axis of rotation, when the measuring-rod has been replaced by the diamond holder.
