A portable machine was needed to resurface a large nuclear station's steam generator keyway slots during replacement. Each keyway slot consisted of three perpendicular surfaces which were irregular in flatness. Prior to installing the new generators, the keyway surfaces had to be machined to its "best possible" flatness condition without removing more than .25" (6.4mm) of parent material.
Wachs Solution:
Wachs was commissioned to build a custom built arbor mounted face mill, supported by an indexable right-angle spindle. The spindle is coupled to a three axis slide deck for precisely positioning the milling head to the machining surface.
