Removing burrs from threaded parts

New England Electropolishing

One challenge manufacturers face is removing burrs from threaded stainless steel parts, such as bone screws, instruments and medical devices.

The problem with these parts is that threads can have burrs at hole entrances and exits or on the sides of thread crests. In addition, the burrs at the start and end of threads can sometimes be thicker than crest threads and positioned in different planes.

When deburring threaded parts, whether by machine or by hand, manufacturers will often remove too much material or destroy nearby part surfaces. This drives up costs, waste, and production time.

Electropolishing, however, is an ideal method for removing burrs while retaining part integrity and meeting tolerances.

At NEE we specialize in precision rates of removal of stainless steel parts. Our exacting process allows us to remove the high points on stainless steel with up to 0.0002” precision.

Electropolishing removes micro burrs from radial edges and precision ground surfaces.

As you can see in both photos, electropolishing gives parts a clean, chrome-like finish while also offering the following benefits:

  • Higher throughput – The process eliminates time-consuming manual deburring as multiple parts can be processed in a single run.
  • Precise finishing – A precisely timed process means parts meet specifications without having to “oversize” them before deburring.
  • Reduced error – Because electropolishing is a chemical process, it eliminates inadvertently damaging other areas of the part during machining.
