UFIBER · CNC Application Case Study
Mark-Free CNC Deburring of Small Stainless Steel 420 Parts.
Replace buffing wheels and manual handling with an automated CNC finish. On a 15 mm stainless steel 420 component, a UFIBER™ Ø5 mm end brush and a Ø1 mm point brush produced a mark-free surface with no buffing or polishing marks, at 10,000 RPM and 200 mm/min, dry. The process was approved for future production.
