Engis Offers Dual Diameter Bore Finishing Solutions

Engis Single Pass Dual Diamter Bore Finishing

 

Engis Corporation Bore Finishing Division has developed advanced tooling and processes for the precision finishing of dual-diameters in components, enabling step-bores to be finished simultaneously while holding diametrical tolerances under 1 micron in a production environment.

Engis precision diamond tooling is manufactured to the highest quality standards, resulting in unsurpassed bore cylindricity, surface finish, and concentricity between each bore. In addition, with the Engis design, separate size compensation for each diameter can be performed easily and in seconds, while the extremely long-lasting diamond tooling helps to reduce the cost per finished piece.

As well as increased production and a reduced number of spindles other significant advantages of single-pass dual diameter bore finishing, include: a split sleeve design which allows for independent size adjustment, separate adjusting nuts, two sleeves on the same mandrel and the improved bore concentricity – with the cylindricity of each bore being under 2 microns.
