Abstract: A method for producing one or more concave cut-outs on a main body, which is in particular substantially cylindrical, more particularly one or more grooves on a magnetic armature, a push rod, or a magnetic keeper plate, includes the following steps:



providing a main body, which is in particular substantially cylindrical and has a first axis of rotation,
rotating the cylindrical main body around the first axis of rotation in a first rotational direction by means of a lathe, and
rotating a striking tool, which is provided with a number of fly cutters, around a second axis of rotation, which extends in parallel and offset in relation to the first axis of rotation in a second rotational direction, which is opposite to the first rotational direction, in such a way that the fly cutter engages in a material-removing manner in the main body to produce the cut-out.

Abstract: A method for obtaining an incision in an embossing roller using a hob to provide protuberances that are rounded on top and which improve the quality of the embossed material and reduce the wear of the mechanical components of the embossing units. The shape of the protuberances is obtained by machining the cylindrical surface of the roller placed between the tailstocks of the lathe using a hob that has teeth, the profile thereof being complementary to the cross-section of the protuberances. A portion of the hob with the teeth generates the grooves that define the side faces of the protuberances. The grooves between the teeth of the hob have a profile that is curvilinear in a cross-sectional view. With a double pass at two different inclinations of the surface of the roller, the protuberances of FIGS. 5 and 6 are generated.

Abstract: A method and apparatus for making a globoid screw for use as a mainrotor in a compressor or expander wherein a cylindrical rotor body is mounted for rotation about the longitudinal axis thereof, a cutter having a plurality of teeth at spaced locations around a circumference disposed in a plane and having an axis of rotation disposed perpendicular to that plane is mounted for rotation about its axis and is disposed so that the plane thereof is parallel to the rotor body longitudinal axis and so that the cutter rotational axis is perpendicular to the rotor longitudinal axis, and the rotor body and the cutter are rotated at synchronized speeds. The rotor body and cutter are positioned relative to each other in a manner moving the cutter axis of rotation and the rotor body longitudinal axis relative to each other to decrease the distance between the axes during rotation of the cutter and rotor body so that the cutter teeth contact the rotor body curing each cutter rotation to remove material from the rotor body by a milling action to form a globoid screw profile including a groove having a pair of spaced-apart sidewalls and extending along the rotor body in a helical path. The relative speed between the rotor body and the cutter is changed by a given amount for a given time to effect a positional change between the cutter teeth and the material of the rotor body thereby resulting in a desired change in the globoid screw profile.
