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.
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
