LFV technology stands for low frequency vibration cutting.
The servo axes are vibrated in the axial direction using
a unigue control technology where by cutting is performed while synchronising
this vibration with the rotation of the spindle.
This cutting method introduces regular "air-cutting" into the cycle,
breaking up of chips into very small pieces making it the optimum processing method
for difficult-to-machine materials.
- Which materials is LFV best suited for?
- Inconel alloy, titanium, stainless steel, iron, copper, nylon, plastic, and more.
1A variety of types of machining can be handled
- Z axis direction
- X axis direction
Finely fragmented chips are discharged smoothly along the flutes in the drill, greatly reducing the number of steps required.
LFV makes it possible.
2Three vibration modes
- Mode 1Designate the number of vibrations per workpiece rotation
- When fine swarf fragments are required
- Mode 2Designate the amount of workpiece rotation per vibration
- When high peripheral speed is required for fine machining or deep, small-diameter holes
- Mode 3Processing method which alters the vibration timing within the threading pass
- When breaking up chips during threading processing is desired
- Conventional cuttin
- Minimizes defects and tool damage caused by chips
- Keeps machining costs low
- Greatly reduces machining downtime due to chip removal
- Less need to monitor machining processes means
more unmanned mass production operations
- Remove chips far less frequently
Q.1Did LFV sufficiently break up of chips?
- Sufficient fragmentation
- Greatly reduced entanglement
Q.2Did LFV result in fewer momentary stoppages?
- No longer a need to check for swarf entanglement
- No change in the number of momentary stoppages
- No momentary stoppages to begin with
Q.3Was the volume of chips reduced?
- By 50-90%
- No real change in collection frequency
- Not sure due to the use of a chip conveyor
Q.4Are you satisfied with the LFV?
- More reliable production quality
- Takes some getting used to, but very effective
- Getting used to having LFV may actually cause problems
- We'd like to extend tool life a bit more
Q.5Will you continue to purchase LFV?
- It is effective for unmanned operations
- Drastically reduces swarf-related problems
- We don't need it on every machine
- Depends on what it will cost
