Thanks to the new rollfeed® turning-rolling inserts from Vandurit and the perfectly adapted hyperMILL® rollfeed® turning strategy, flawless workpiece contours can be achieved in no time at all. What makes this turning method so clever is how the tool’s cutting edge rolls off the workpiece surface, regardless of contour. The large radii on the insert, ranging from 17 to 19mm will allow a much higher feed rate and greater cutting speed than with conventional inserts and deliver a twist-free finished surface.
The rollfeed® indexable inserts achieve a significantly better surface quality than conventional inserts with a radius of only 0.4mm or 0.8mm, especially at high feed rates. The improved cutting conditions also extend the service life of the rollfeed® tools by 300-500 percent.
