Eliminate Machining & Welding Defects

  • Up to 50% improvement in surface finish (Ra)
  • Remove alpha case (titanium) and EDM recast layers
  • Eliminate embedded free iron, grinding compounds, oil, and light rust
  • Remove microscopic burrs, cracks, and rough edge radius
  • Prevent threaded part galling
  • Remove heat treat tint and scale
  • Remove the effects of carbide precipitation

“I wanted to express how grateful we are that Able is our partner. Everyone is professional, helpful and so kind!
Thank you for all you do.”

– Phylis Corso, Purchasing & Procurement Manager, R.S. Precision, Inc.

“…our customer put us up against a wall with an extremely hot job. Of course, Able was the last service required and you and your crew handled the passivating job flawlessly. You even completed it two hours sooner than originally promised. We needed every bit of that two hours to tie things up on our end. Thank you. Please also thank everyone involved on your end who helped us miraculously meet our deadline.”

– Kevin Graff, Owner & General Manager, NJC Machine Co.

“I don’t know who found Able for us to try the electropolishing route, but it’s a night and day difference.”

– Quality Manager, Fastener Manufacturer & Distributor

“Working with Able has been fantastic. When you really sit back and look at the amount of parts and all the (logistics) movement … they’ve done a pretty fantastic job of doing it all. You can send parts over there and everything gets taken care of.”

– Marine Hardware OEM & Able Trusted Supplier Network User

“We consider Able Electropolishing to be a key partner. They do great quality work, and because everything is customized, it’s very quality-focused. We always say that Able is like a big brother. We like how they handle communication, paperwork turnaround time, the finish… just the whole gamut. That’s why they’ve been such an integral part of our business.”

– Martha Salazar, Regional Sales Manager, Acme Wire Products

“My start up uses Able to electropolish and passivate some of our medical devices. They do high quality work with very short lead times. The results have been very consistent in terms of quality. Overall we were quite satisfied.”

– SB

“We use Able to electropolish and passivate some of our surgical instruments. They were able to work with our other suppliers and coordinated drop shipments so that we would get our instruments microfinished in time. Their customer service is very helpful.”

The Top 10 Benefits of Electropolishing

When metal parts are machined, a range of compromising imperfections – including microcracks, microburrs, stains, free iron, and Electrical Discharge Machining (EDM) recast – are often left behind. These small but significant imperfections can lead to a host of bad…

How Electropolishing Removes EDM Recast Layer

Electrical Discharge Machining (EDM) is a widely used manufacturing process known for its precision and ability to machine hard materials.

Alpha Case in Titanium Parts: Challenges & Solutions

Titanium alloys are critical in industries requiring high strength-to-weight ratios and corrosion resistance, such as aerospace and medical technologies.

Getting to Know ASTM, SAE, and ISO Standards

In an undertaking as meticulous and methodical as electropolishing and passivation, it’s important to get the details right. That includes meeting the criteria established by outside standard-setting bodies that ensure the highest-quality materials and parts for critical industries like pharmaceuticals,…
