SUB-MICRON TOLERANCES AND SURFACE FINISHES LESS THAN 1 RA

Oberg Industries (Freeport, PA) offers advanced grinding technology with Molecular Decomposition Process (MDP). Developed for the most efficient removal or cutting of any conductive material, MDP uses an electrochemical action and an abrasive wheel to achieve surface finish of less than 1 RA and precision tolerances held to 0.0002 in – all without generating heat. The process is ideal for use with consumer or industrial products where surface finish and dimensional stability are imperative such as grinding surgical needles, sharps and razor blades.

The Molecular Decomposition Process is also suitable for applications requiring a surface free of micro cracks and fissures or other highly polished, weight-bearing and articulating surfaces. Gentle enough to grind thin-walled components without damage or distortion, MDP works well with tubing, rapid cut-off needs and grinding of complex features in exotic metals, including nitinol.

"No other method of grinding or cutting can compare in performance with speed, precision, repeatable accuracy and clean operation," said Joe DeAngelo, Director of Technical Development, Oberg Industries. "MDP can even eliminate secondary operations such as electro polishing, micro blasting and deburring without generating thermals or causing internal stress and distortion in the material. Its applications are endless."

During Molecular Decomposition Process, an electric current flows between the negatively charged abrasive wheel and the positively charged work piece through an environmentally friendly electrolyte (saline) solution. A decomposing action occurs causing the material surface to oxidize. This oxidized surface is then removed by the specially formulated abrasives in the wheel exposing more material and repeating the cycle.

MDP cuts conductive materials 80 percent faster than conventional methods and is especially effective on super-alloys and exotic metals. It can be used with the following conductive materials:
? Aluminum
? Beryllium
? Cobalt chrome
? Copper
? Inconel
? Iridium
? Molybdenum
? Nickel
? Nitinol
? Platinum
? Rhenium
? Single crystal alloys
? Stainless steel
? Titanium
? Titanium carbide
? Tungsten carbide
? Zirconium
? Other conductive ceramics and plastics

After working closely with Compositron Corporation, based in Brooklyn, NY, for over five years to further develop and refine the Molecular Decomposition Process, Oberg acquired the MDP technology and the full consumable products line of Voltron grinding wheels and electrolyte in July 2007. Voltron grinding wheels and electrolytic solution continue to be manufactured and developed at Oberg's Sarver, PA, campus to fit a variety of cutting and grinding applications.
