At Last - An Affordable Stone or Tape Microfinishing System

The cost effective 640-FX meets low, medium, and high production requirements while providing flexibility to adapt to future parts. Fast changeover and easy programming are a feature of this machine. Machine has a dry floor design and is shown with an optional mist control system.

In the application shown, cam lobes are finished with stones to generate the desired surface finish., each bank of lobes (4-banks for 4 cylinder and 5-banks for 5cylinder) are finished with two level stone microfinishing. Mains are microfinished in a single level operation with coated abrasive film.

Bearing journals are microfinished with the IMPCO “GBQ” process. The patented “GBQ” process uses non-resilient formed inserts backing the coated abrasive film. Synchronized with the machine cycle, the film is automatically indexed between each cycle. This process improves circular geometry up to 80% while generating surface finishes to less than .2um.
