Abstract

Apparatus holds in alignment a stack of a plurality of loose laminations so that clamp bolt holes therein are held in an accurately aligned condition while the stack is compressed (in the vicinity of the bolt holes) between pads that simulate mounting pads in a compressor, and a means for applying a force localized in the bolt hole regions. The compressive forces simulate and closely approximate the compressive forces that ultimately will be applied to the bolt hole regions under the heads of mounting bolts in a compressor. Various eccentricities and dimensional variations between the bore and bolt holes are transferred to the bore, and while the stack is held with the preselected compressive forces, the bore is shaped with a roller burnisher so that it will be concentric relative to the bolt holes.
