    Single-Pass Honing & Bore Finishing Systems

    Contact Engis Engis Corporation Engis Corporation
    For high volume applications, Engis Single-Pass bore finishing systems are the unsurpassed solution for forward thinking manufacturers to improve roundness, concentricity and finish.

    Engis' single-pass bore finishing process uses fixed-size bore finishing tools coated with diamond abrasive particles. These tools pass through the bore only once, removing a specific amount of material. Using a series of progressively larger bore finishing tools (coated with progressively finer superabrasive particles) enables extremely tight tolerances, reliably and consistently, at a lower cost per part.

    Traditional vertical honing machines cannot match the benefits and capabilities of the Engis systems approach. Engis single-pass bore finishing capabilities include:

    • Size control as good as 0.001mm in production.
    • Bore geometry as good as 0.0005mm in production.
    • Surface finish to better than 0.1µm Ra in most materials.
    • Shorter cycle times.
    • Quality bores even with lower skilled operators.
    • Blind bore and cross-hatching capabilities.
    • Predictable, consistent results that lend themselves to statistical
      process control.
    • Extremely long tool life.
    • Lower overall cost per finished piece.

    Applications for single-pass bore finishing can be found in a wide variety of industries, including automotive, hydraulic, advanced ceramic, compressor, aerospace, firearms, and medical. Learn how Engis helped to improve productivity at Bobcat by 300%.

    Originally developed for cast iron, Engis advancements now make single-pass process suitable for both hard, soft and “gummy” metals and materials, including ceramic, steel, aluminum, bronze, brass and chrome.
