More Efficient Turning With rollFEED® Turning

OPEN MIND is offering an exclusive hyperMILL® strategy that is perfect for the rollFEED® Turning method developed by Vandurit. Machining times and tool wear are considerably reduced while retaining maximum process reliability.

Achieve perfect workpiece contours in the shortest possible time – this approach has enabled Vandurit to develop the innovative rollFEED® Turning method. The highly efficient method makes turning faster than ever before! A feature of this unique 3-axis turning operation is the rolling of the complete insert contour on rotationally symmetric surfaces. The cutting movement is produced by the horizontal swivelling of the B-axis with simultaneous compensation for the X and Z-axes. rollFEED® Turning can be used for all standard materials together with the appropriate cutting materials.

Collision-checked CAM strategy

OPEN MIND has developed an exclusive CAM strategy for this innovative turning method in collaboration with Vandurit. The hyperMILL® rollFEED® Turning strategy is perfectly adapted to Vandurit’s three rollFEED® Turning components. This includes inserts, a tool system and a drive unit that makes it possible to retrofit lathes that do not feature a third axis. The easy-to-program turning operation avoids unnecessary tool changes. This reduces tool consumption and inventory. The entire turning operation is fully checked for collisions. The complete rollFEED® Turning process is taken into account during programming and simulation. This includes the geometries of the tool and tool holder plus their movements.

Application: grooves with just one tool

rollFEED® Turning allows grooves to be machined with a single tool in a single movement. The hyperMILL®CAM strategy automatically guides the tool from the first to the second plane level via the cylinder surface. Thanks to the combination of roll and turn movements, even workpieces with large radii can be machined with full collision checking, providing full process reliability.

Areas of application

  • All materials can be machined
  • All cutting materials can be used
  • For inside and outside machining
  • Diverse applications: for plane levels, cylinder, convex and concave surfaces as well as for inclinations and grooves

The rollFEED® Turning components

rollFEED® insertsrollFEED® inserts

Only two rollFEED® inserts are required for all 3-axis turning operations. The hyperMILL® rollFEED® CAM strategy and the unique tool geometry makes it possible to cut up to three component sides in a single movement.

QuickChange tool systemQuickChange tool system

The QuickChange tool system is another rollFEED® component. Specially developed base plates are used as supports for the unique rollFEED® inserts.

rollFEED® drive unitrollFEED® drive unit

With their X, Z and B-axes, turn-mill machines have a third axis. For lathes without a third axis, the rollFEED® drive unit is mounted on the turret and used like a driven tool.

  • Perfectly finished surfaces free of twists (if necessary)
  • Simple to program
  • Fewer tool changes
  • Undercuts can be integrated into rolling movement
  • Possible to upgrade existing machines
