Slotted Stainless-Steel Medical Tube – Edge Prep

Automate the edge-break and deburring process for slotted 304 stainless-steel medical tubes without reducing the internal diameter. A 0.0195” plug gauge must pass freely after tumbling.

Bel Air developed a centrifugal barrel finishing/harperizing process to deburr and break the edges of slotted 304 stainless-steel medical tubes while maintaining the inner diameter.

The process used precision ceramic media—a fine-grain, aluminum-oxide–based media that delivers a smooth finish with controlled metal removal. Its medium wear rate and balanced cutting action allowed consistent edge refinement without closing the 0.0195″ I.D.

This method eliminated manual deburring and produced a clean, uniform edge finish that met the plug-gage tolerance requirement for precision medical components.

If you are unsure what equipment and media you require to achieve your desired surface finish, then send us your part, and we will evaluate it and provide you with a metrology report.
