 require appropriate professional skills and experience.   A customized solution for machining steering knuckles
        provides an excellent example of these combined
        tools. ISCAR proposed this solution as a part of a
        turnkey project for one of the biggest car producers.
        The combined assembled tool performs several
        operations - cutting inner thread in holes for dust
        shield by tapping; milling two grooves (for snap ring
        and grease seal) by helical interpolation; and milling
        the outer face. The tool carries different radially
        and tangentially clamped inserts and has a tapping
        attachment with a misalignment compensating
        mechanism. The strict tolerance limits for linear
        dimensions ensure successful utilization of the tool
        in multi-spindle machines.


        It turns out that machining cast iron is not such a
        simple matter after all, as is sometimes believed.

 to producers of cast iron parts. The tangentially
 clamped inserts are positioned in a TANGFIN cutter
 with a gradual displacement in both radial and axial
 directions. The design causes each insert to cut
 only a small portion of the material. This concept,
 together with the high-rigidity tangential clamping
 principle and the long wiper edge of the insert,
 results in an impressive machined surface finish,
 with an Ra up to 0.1 μ (4 μin) roughness parameter.
