Electropolishing

Features:

  • Electropolishing system works it’s wonders by smoothing, polishing, and deburring metal surfaces in an electrolytic bath.

  • Removes high points on the metal surface while producing a uniform high luster on the metal surface.
  • Metal part is immersed in a liquid media and subjected to direct current.
  • The metal part is made anodic (+) and a metal, usually lead, copper. or stainless steel, is made chathodic (-).
  • The direct current flows from the anode to the cathode removing metal ions at a controlled rate.
  • The amount of metal removed is dependent upon the specific bath, the temperature, speed, and the particular alloy being electropolished.
  • Unlike conventional mechanical finishing systems. this process does not smear, bend, stress or fracture the crystalline metal surface to achieve smoothness or lustre.
  • Removes metal from the surface producing a unidirectional pattern that is stress and occlusion-free, microscopically smooth, and often highly reflective.
  • Improves corrosion resistance and passivity are achieved on many ferrous and some nonferrous alloys.
  • Used for micro- and macro-deburring, as this reverse plating process selectively removes metal ions from the high points on the surface without etching it.

Electropolishing for Deburring

  • A Polishing & Deburring System for Ferrous & Non-Ferrous Metals.
  • With this unique system, the following metals and alloys can be electropolished and deburred in one step: 200, 300, 400 Series Stainless Steel Certain Nonsilicon Aluminum Casting Alloys Low Carbon Steel Wrought Aluminum Alloys High Carbon Steels Inconel Low-Alloy Steels Monel Copper and Beryllium-Copper Alloy Hastelloy Brass Waspalloy Bronze Titantium Nickel Compressor Blade Alloys Nickel-Silver Gold
  • Only limited success can be achieved with cast metals. Generally alloys containing silicon, sulfur or carbon, in appreciable amounts, will not elecrpollish.
  • Stainless steel investment castings are well suited for this process, but Aluminum and Zinc die castings are not.
  • The type of solution, its metal removal rate solution control techniques and recommended current density range for each metal or alloy are proprietary
