I have some rollers made by SKH 51 material. Could i use the electrochemical polishing technique to polish the surface of the SKH51 rollers?
SKH 51 (C:0.8~0.9, Cr:3.8~4.5, Mo:4.5~5.5, V:1.6~2.2, W:5.5~6.7)
In materials that are multi-phase you tend to get different attack rates when you EP. The result is that while you might improve the microscopic texture of the surface you could cause some pitting at or arround one of the phases.

Corrosion never sleeps, but it can be managed.
Let me look around my information for ways and means to do a vibratory or tumbling type polishing on the parts. The are a lot of new processes out there using newer abrasives and diamonds.
How critical is the diameter?
What are the quantities that need to be processed?
Electrochemical etch. You print the mask or pattern on the surface and then acid etch the rest away.
You might be able to laser scribe the surface to get the same effect.
