In a special case of micro vascular eye surgery, Finish Line became a direct and active participant of the research, due to importance and no-thoroughfare situation in manufacturing of the main surgery instrument, a metal surgery needle.
The Project’s need for that stage was a surgery needle with Outer Diameter of just a few tens of microns, nearly ten microns wall thickness, with just a few millimeters length. The best one the developers have managed to provide was Outer Diameter about 100 microns, heavy oxidized and having burrs at the edge’s outer and inner sides.
Special efforts were made by Finish Line to handle this under-microscope managing process (view pic.), to control the sub-microamperes current density, to ensure a correct location of the piece inside the electrolyte bath, and so on. Evaluation of tests’ results was performed by the Customer at the place with X40 measuring microscope, to facilitate the try and error elaboration process.
Eventually, due to mutual efforts, the appropriate Eye Needle Electropolishing Process (view PDF) has been determined, resulting in smooth clean burrs-free surface of the needle, with its Outer Diameter reaching the goal sizes range. Tens of the needles were successfully manufactured for clinical tests.

Anode Treatment

Anode treatment beneficiates metal surface through metal dissolving and oxidation. In case no coating is allowed, Anode Treatment is a way to enhance your parts’ surface qualities. more >>


Passivation is a classic anode treatment to improve corrosion resistance of metals, comparing to not treated parts, through completing natural formation of metal oxides surface layer. more >>

Bright Passivation

Bright Passivation improves corrosion resistance of metals, comparing to not treated parts, removes spots from previous processing and provides the parts with brighter appearance. more >>


Etching is an old craft which technically comprises a vigorous anode treatment process, widely exploited in industry. Etching metal surface as a whole makes it uniformly rough and porous more >>

Color Anodizing

Color Anodizing is a unique Titanium only applied process granting to metal surface a wide spectrum of controllable vivid interference colors, which are stable, uniform and repeatable more >>

Surface preparation

Surface preparation ensures the after Anode Treatment surface features as aimed. It includes both quality improving (like de-burring) and surface beneficiation (like surface roughening) more >>

Surface cleaning

Surface Cleaning is an essential completing operation after any Anode Treatment intended washing the surface from leftovers of previous treatment, using purified water at the end step more >>
