Innovative rollfeed® turning process

A partner­ship for unequaled performance: Together with Vandurit, OPEN MIND developed a CAM strategy that is perfectly aligned with the innovative rollfeed® turning process. The use of these inserts with particularly large radii results in significant time savings.

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.

rollfeed® indexable inserts

Some­times less is more. Only two rollfeed® indexable insert geometries are required for finishing. The T insert is suitable for machining up to three work­piece sides; the X insert allows for processing up to two work­piece sides.

Perfect surfaces despite high feed rate

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.
