At the recent MACH exhibition in Birmingham, Citizen Machinery showcased the latest evolution of its patented LFV (low-frequency vibration) chip-breaking technology, marking the first major UK exhibition demonstration of four-axis simultaneous LFV capability. Although the advanced functionality was first unveiled during Citizen’s open house in Brierley Hill last autumn, MACH 2026 provided the first opportunity for a wider manufacturing audience to see the technology in action across multiple machine platforms.
Originally introduced more than a decade ago, LFV technology is integrated directly into the operating system of Citizen Cincom sliding-head lathes and selected Miyano fixed-head models. Unlike conventional chip-breaking macros, the system synchronises high-frequency vibration with spindle rotation to create intermittent cutting, effectively breaking long, stringy swarf into manageable chips.
The latest development allows LFV to operate simultaneously across four axes: the X and Z movements on both the main and sub spindles. The result is greater machining flexibility, reduced cycle times and uninterrupted production, particularly during unattended operation and when machining malleable materials such as stainless steel, titanium, aluminium, copper alloys and plastics.
Five turn-mill centres equipped with four-axis LFV were demonstrated at the exhibition, including three Miyano fixed-head lathes and two Cincom sliding-head models. Among the highlights were the new Miyano BNX-65MSY and the Cincom L32-X series 2, both capable of superimposed machining with up to three tools cutting simultaneously to maximise productivity.
Citizen also demonstrated the breadth of its portfolio with two contrasting machines: the Miyano ABX-80THY, machining large-diameter components from 80 mm bar, and the Cincom R04-VI, producing intricate 2 mm diameter parts. Together, the demonstrations reinforced Citizen Machinery’s ability to deliver high-precision, lights-out manufacturing solutions across a wide range of component sizes and applications.
