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 – which can have any contour. The large radii on the insert, ranging from 17 to 19 mm, 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 0.4 mm or 0.8 mm, especially at high feed rate. The improved cutting conditions also extend the service life of the rollfeed® tools by 300-500 percent.
