1. In an apparatus for micro-finish machining of cylindrical or conical surfaces, of total length (D), on rotating workpieces, and in particular for the raceways of cylindrical or tapered roller bearings including a honing tool, the improvement comprising:

  • (a) a first slide means engaging the honing tool;

    (b) means mounting the first slide means relative to the workpiece so that it and the honing tool will experience a first oscillation relative to the surface to be machined, whereby the stroke of said first oscillation is determined such that it is short as compared with the total length of the surface to be machined;

    (c) second slide means to which the means mounting the first slide means is mounted; and

    (d) drive means connected to the second slide means for driving the two slide means, the means mounting the first slide means and the honing tool so that the first slide means and the honing tool experience a second oscillation relative to the surface to be machined, whereby the stroke of said second oscillation is determined such that the path of the tool as determined by said second oscillation, essentially extends over the total length to be machined;

    wherein the drive means comprises;

    (i) a drive motor;

    (ii) a rotating part connected to the drive motor and to the second slide means, said rotating part having tab means extending outwardly therefrom;

    (iii) sensing means provided along the path of motion of the tab means; and

    (iv) arresting means connected to the sensing means and to the drive motor, said arresting means serving to arrest the drive motor for an adjustable length of time as a function of the time lapse between sensed positions of the tab means by the sensing means.
