  • Publication number: 20200156204
    Abstract: In the case of a honing method for machining the internal face (214) of a bore (210) in a workpiece (200) with the aid of at least one honing operation, during a honing operation a flaring-capable honing tool (150) that is coupled to a spindle is moved back and forth within the bore for generating a reciprocating movement in the axial direction of the bore, and are simultaneously rotated for generating a rotating movement that superimposes the reciprocating movement. A bore shape having an axial contour profile which is rotationally symmetrical in terms of a bore axis (212) and deviates from the circular cylindrical shape is generated herein. For generating an axially variable material removal in at least one stroke modification phase a stroke length and/or a stroke orientation of the reciprocating movement is modified.

  • Patent number: 6255506
    Abstract: A very effective catalyst system for the polymerization or copolymerization of olefins comprises a cocatalyst, preferably an aluminoxane or a supported aluminoxane, and a metallocene of the formula I in which, in the preferred form, M1 is Zr or Hf, R1 and R2 are halogen or alkyl, R3 is alkyl, R4 to R12 are alkyl or hydrogen and R13 is a (substituted) alkylene or heteroatom bridge. The metallocenes, in particular the zirconocenes, produce polymers of a very high molecular weight, in the case of prochiral monomers polymers of a very high molecular weight, very high stereoactivity and very high melting point, at high catalyst activities in the industrially particularly interesting temperature range between 50 and 80° C.
