rollfeed® turning: A quantum jump
in evolution of turning.


World premiere on EMO 2017.

Presented in September 2017 on fair EMO in Hannover/Germany, the new innovative turning process ROLLFEED® turning impressed visitors for the first time in public.

The Process

rollfeed ® turning enables the rollover of insert contour being a cutting edge on rotationally symmetrical surfaces of any shape. Rollover motion is generated by rotation of the tool with simultaneously compensation of arising center offset by X- and Z-axis of the machine-tool. The unrolling feed synchronously overlays the contour parallel feed rate. By utilization of known cutting materials rollfeed ® turning can be applied in all known work piece materials.

Some of the benefits of ROLLFEED® turning:

  • Massive Cutting Performance
  • Tool-Life Multiplication
  • Minimizing Tool Changes
  • Reduction Of Tool Variation
  • Increasing Productivity
  • and much more

System Components

The rollfeed ® process contains different system components depending of your machine type. Get an overview and detailed informations on this page:

The programming of rollfeed ® process can be done with different possibilities: You can use Vandurit rollfeed ® macros (programming online) oder use the module “rollfeed ®” in hyperMILL® von OpenMind.


This is the most individual part of the rollfeed ® installation. Depending on your machine type you will need an individual adaption or – f.e. with a B-axis machine – you need no particular adaption.

rollFEED® unit

Due to rollfeed ® units almost every CNC machine is able to use the rollfeed ® benefits. There is no need of installing a unit with MillTurn machines, because the B-Axis of the machine is used instead.

QuickChange (Capto) precision tool holder

quickchange precision-tool-holders are equipped with particularly designed pockets for rollfeed ® inserts.


ROLLFEED® inserts

Due to unique geometry of rollfeed ® inserts 3 sides of a workpiece can be machined – in one movement. The movement of the heating point of the operation through rolling the cutting edge significantly increases tool life.
