LFV

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.
