Engis Single-Pass Superabrasive Bore Finishing Systems

The Engis Diamond Bore Finishing System integrates advanced CNC machine tool technology with the diamond and CBN tooling capabilities of Engis. The result is single-pass bore finishing with flawless precision and unmatched reliability.

High Performance Equals Close Tolerances -- In A Single Pass:

Engis single-pass bore finishing systems are capable of repeatedly and reliably generating bore sizing to better than .0001" (.0025 mm), with bore roundness, straightness and taper to as good as 20 millionths of an inch (.0005 mm). Surface finishes as good as 4 microinches (.1 Ra. micrometer) can be attained.
