Low Frequency Vibration (LFV) is Citizen’s widely applicable cutting technology designed to avoid the problem of spiraling chips, entanglement of chips and built-up edges. In LFV cutting, “air cutting” time prevents the machining temperature from rising, which gives relief from various problems caused by chips and virtually eliminates the need for high pressure coolant. LFV is ideal for cutting difficult to cut materials in a broad range of shapes (including hard metals and soft plastics). This technology breaks up chips into very small pieces so they don't become entangled with the material or tool. Benefits include prolonged tool life, reduction of down time, improved surface finish, exceptional part accuracy, and increased throughput.
