How much material does Electropolish remove?

How much material does Electropolish remove?

Material removal is commonly only 0.0003″ to 0.0007″ for most deburring and polishing applications after machining. With precise monitoring, electropolishing can remove as little as 0.0001″. For an electropolishing process with longer cycle time and amp-minutes, as much as 0.003″ to 0.005″ of material may be removed.

Can you Electropolish 303 SS?

Type 316 generally polishes better than Type 304. Type 303 stainless possesses sulfide inclusions, which presents an obstacle to high-grade electropolishing. Generally, electropolishing can reduce the Ra or RMS reading on a mechanically polished surface by approximately 50 percent.

What metals can you Electropolish?

Commercially Electropolished Metals Include:

• Stainless Steel.
• Low and High Carbon Steels.
• Tool Steels.
• High-Temperature Alloys (Molybdenum, Nimonic, Waspaloy, Tungsten)
• Aluminum.
• Titanium.
• Copper.
• Kovar.

Why do we Electropolish stainless steel?

Electropolishing stainless steel is a “reverse plating” process that uses an electrochemical solution to remove the outer skin of a metal part. Electropolishing stainless steel significantly, especially 300 and 400 series stainless steel, improves a part’s corrosion resistance, leaving it with a lasting bright finish.

Can 303 stainless steel be passivated?

303 ss has high sulfur or selenium to provide good machinability, etc. It is the sulfur or selenium that gives the apparent problem in passivation. In order to passivate 303 stainless steel you must first remove the sulfides and sulfates from the surface (or selenium in the case of 303Se).

Can you Electropolish mild steel?

Following the electropolishing treatment, parts are deburred and have a smoother, bright finish….Electropolishing & Deburring Service for Carbon Steel Alloys.

Can you Electropolish bronze?

It has been demonstrated that the process of electropolishing of two kinds of bronze (AMPCO® 22 and AMPCO® 712) can be performed in Ethaline at the electrode potential of +2.5 V and the temperature of 25 °C for 20 min.

What are the limitations of electropolishing?

Electropolishing as a Secondary Finishing Process The electropolishing process does have limitations. The maximum improvement in surface roughness (Ra, or roughness average) is 50%. So if a freshly-machined part has a surface roughness of 80 Ra, the best you can achieve with electropolishing is 50% of that, which is 40 Ra.

What is the best surface roughness for electropolishing?

So if a freshly-machined part has a surface roughness of 80 Ra, the best you can achieve with electropolishing is 50% of that, which is 40 Ra. Some parts may require preliminary finishing through mechanical means to meet stringent surface-finish requirements.

Why choose an electropolishing company?

Specialist electropolishing companies ensure that environmental, health and safety standards are met. In rinsing, it must be taken into account that electropolishing solutions are viscous and do not mix readily with water.

How to choose the right electropolishing machine?

The ideal choice for daily electropolishing jobs is the Cougartron FURY 100. You must also pay attention to not over polish the surface as this may obstruct its (re) passivation. Choose the right liquid: Electropolishing with Cougartron machines is done in combination with CGT-550 Weld Cleaning & Polishing Fluid.
