Low frequency vibration cutting

With low frequency vibration cutting, the vibration control in the axial direction of the servo axis do the cutting while sync with the spindle rotation. By providing a time "air cut" during cutting, it can be discharged intermittently chips and keep in a stable satisfactory machining state.

Citizen's Low Frequency Vibration Cutting (LFV) claims to eliminate stringy swarf. The LFV process is activated through a G-code in the CNC program enabling an on-demand initiation anywhere in the cutting cycle.

The servo axes of the drive system are ‘vibrated’ in the direction of feed in phases involving tens of microns which are synchronised to the rotation of the machine spindle. As a result, regular ‘air-cutting’ is introduced to the cycle which breaks swarf into small chips.
