A new tool removes oxidants on the edges and surfaces. Achieved by means of the sudden, hard strokes by the perfect shaped spring threads. Used in one of the FLADDER® deburring machines a perfect result is achieved thanks to the patented, wellproven method where the workpieces are being uniformly “brushed” due to the 4 different movements by the machine. The power of the stroke is created by the centrifugal force - a principal that has been used by the FLADDER® Finishing System for centuries. Simple and yet effective.
