Ultra-precision mirror surface processing "Electrolytic Composite Polishing"
Electrolytic composite polishing
"Electrolytic composite polishing" that achieves a nano-level mirror finish.
This is a polishing method that achieves a nano-level ultra-smooth surface by simultaneously combining electrochemical polishing and physical polishing with abrasives. 【Features of Electrolytic Composite Polishing】 ◆ Achieves a high mirror finish at the nano level Even pure titanium can be finished to an average roughness of 0.002 µm (2 nm) from an average roughness of 0.2 µm. Furthermore, depending on the polishing conditions, it is also possible to achieve an average roughness of 0.001 µm (1 nm). ◆ No distortion of the metal surface due to heat In physical polishing, distortion of the metal surface due to heat may occur, but this does not happen in electrolytic composite polishing. ◆ Clean surface properties with minimal alteration No compressed altered layer forms on the metal surface. Additionally, there is no entrapment of abrasives, resulting in a very clean surface. ◆ High non-adhesiveness and cleanability A smooth metal surface exhibits excellent non-adhesiveness and cleanability. ◇◇ For more details, please download the catalog or contact us ◇◇

[Surface Treatment Example] Mirror Polishing of Stainless Steel Foil with a Thickness of Several Tens of Micrometers This is a treatment example of stainless steel foil (SUS430) subjected to electrolytic composite polishing. Electrolytic composite polishing can achieve a mirror finish even on shapes that are several tens of micrometers thick and easily bendable, as shown in the photo, or on materials with fine holes.

[Surface Treatment Example] Mirror Polishing of Joint R Parts by Electrolytic Composite Polishing This is a case study of electrolytic composite polishing applied to the joint R parts of a SUS304 sample. Electrolytic composite polishing can accommodate a wide range of shapes, including joint R parts that are usually difficult to polish, inner surfaces of pipes, complex inner surfaces, inner surfaces of combinations with different diameters, and thin shapes like foils.
