Automated CNC Deburring of Small Stainless Steel Components UFIBER Ceramic Brush Case Study – SS 420

Industry: Precision CNC machining, automated deburring, and surface finishing for stainless steel components.

Objective:

To achieve mark-free CNC deburring and high-quality surface finishing on a small stainless steel 420 component, eliminating line marks caused by traditional buffing wheels.

The customer also aimed to replace manual deburring of small parts with a repeatable, automated CNC process suitable for future production volumes.
