Low-frequency vibration-assisted turning

Turning is of great importance as the primary process for manufacturing rotationally symmetrical components. With VIBROturn, chip breaking is improved during turning, thereby increasing productivity and process reliability.

Chip problems and chip flow

In turning, the chip breaking problem has not yet been solved in a reliable way. The reasons for this lie in the continuous cutting engagement. Insufficient chip breaking can cause a variety of problems:

  1. Formation of long and difficult-to-handle chip shapes and tangled chips.
  2. Long chips lead to process uncertainties – damaged workpiece surfaces, tool breakage and clamping errors can be the result.
  3. Chip piles pose collision hazards.
  4. Chip piles hinder the removal through chip conveyors as well as the automation.
  5. Process stops for manual chip removal reduce machine availability.
  6. Increased risk of injury for manufacturing personnel when handling jammed chips.
  7. Frequent change of chip containers due to high chip space.
  8. Chip processing is inefficient.

You can overcome these challenges – with our VIBROturn low-frequency vibration systems.

VIBROturn generates a defined oscillation of the tool, introducing predetermined breaking points to enable a process-secure chip breaking. Where previously turning machines had to be stopped several times an hour for manual chip removal, even in series production, chip breaking now no longer causes interruptions of production. By avoiding downtimes, productivity is significantly increased.

Process uncertainties caused by chips, such as scratched surfaces, clamping errors, tool breakages, etc., are prevented by the short broken chips. VIBROturn uses tools for external and internal machining. This supports processes such like longitudinal turning, face grooving, parting off up to centric drilling with a low-frequency vibration.
