Technology With Commitment



What is LFV

The servo axes are vibrated in the axial direction using a unique control technology whereby cutting is performed while synchronising this vibration with the rotation of the spindle.

Because “air-cutting” times are provided during cutting, this technique is also characterised by intermittent expulsion of fine chips. This has made it possible to resolve problems such as chip entanglement and built-up edges at a stroke.

Vibration cutting can handle a variety of types of machining in addition to linear machining on faces, including tapers, arcs, and drilling across a wide range of machining geometries and materials.

Vibration cutting can be turned ON and OFF just by inserting G codes in machining that has proved difficult up until now, such as the machining of deep holes and micro-machining.


Citizen LFV Cutting Technology – Reduced Chip Sizes

  • Chips are broken up and do not become entangled with the material or tool.
  • Cutting resistance is lowered.
  • Programmable chip control
  • Reduce or remove the need for high pressure coolant
  • No built-up edge is formed.
  • The machining temperature doesn’t rise so there is little susceptibility to distortion.
  • Tool life is extended.
  • Very fine cuts are possible.

  • Citizen's Enhanced Low Vibration Cutting (LFV) Technology

  • Citizen’s enhanced Low Frequency Vibration cutting method utilises X and Z axis servos which are designed to vibrate in cutting feed direction.
  • The vibration is synchronized to the main spindle.
  • “Air cutting” allows to generation of smaller chips by interrupting and overlapping subsequent cuts.
  • Citizen’s LFV is very flexible allowing a wide variety of work to be machined.
  • Easy to use – Just add “Vibration start” and “Vibration stop” to the conventional program to enable the LFV methods to be used.

  • Chips 2

    Citizen's Low Vibration Cutting (LFV) Technology

  • Ideal for difficult to machine materials – Chip control/Tool Life extension
  • Malleable materials such as copper and plastic, previously impossible to control chips – easily controlled with LFV.
  • Break up of chips into very small pieces
      • *Reduction of down-time/increase in productivity and profit
        *Efficiency Through a combination of vibration and Standard-cutting
        *Very fine work pieces are possible
        *Excellent for deep hole drilling
