POLISHING ECM
Polishing ECM, also known as Electrochemical Polishing, provides a superior, mirror-like surface finish on parts, particularly for sanitary and high-purity systems. It is a non-contact process that saves significant time over traditional manual methods.
Materials Machined
- Stainless steel (304, 316L, etc.)
- Copper and its alloys
- Nickel-based alloys (e.g., Inconel)
- Titanium
Market Sectors
- Medical: Surgical instruments, implants, and equipment.
- Food & Beverage: Brewing tanks, pipes, and fittings.
- Pharmaceutical: High-purity process lines and valves.
- Luxury Goods: Watch components and jewellery.
- Aerospace: Fuel lines and hydraulic systems.
- Cosmetics: Skincare devices, dispensers, fine tips and brushes without secondary finishing
Key Benefits & Numbers
- Exceptional Surface Finish: Achieves a mirror-like finish with Ra values as low as 0.01-0.03 µm. This is a significant improvement from initial machined surfaces, which typically have an Ra of 0.5-3.2 µm.
- Reduced Cycle Time: Cuts polishing time by up to 90% compared to manual or abrasive methods. A typical fitting can be polished in seconds.
- High Dimensional Integrity: Removes material evenly, with a stock removal of just 5-20 µm, without altering the part’s geometry or creating a heat-affected zone.
- Eliminates Secondary Operations: The process is burr-free, removing the need for a separate deburring step and streamlining production.
Relevant Industry Standards
- ASTM A967: Standard Practice for Chemical Passivation Treatments for Stainless Steel Parts.
- ASTM B912: Standard Practice for Passivation of Stainless Steels Using Electropolishing.
- ASME BPE: The primary standard for bioprocessing equipment, which specifies surface finish and cleanability for high-purity applications.
