LFV technology
LFV technology is a unique Citizen control technology which breaks up the chips by vibrating the servo axis in the cutting direction and providing “air-cutting” time where the tool does not touch the material. As a result, this achieves solutions to various issues regarding chips, which has been a challenge for many years in the cutting process, such as improvements in the efficiency of small-diameter, deep-hole machining and fine cutting of chips produced when working with difficult-to-cut materials where the resulting chips have tended to be quite long. In addition, this technology achieves machining with high precision for an extended period of time by dramatically reducing the chip volume and preventing defects on the workpiece surface.
