In Hall 20 Stand 150, Citizen’s LFV (low-frequency vibration) chip-breaking software will feature strongly. The patented system is being rolled out across the company’s Cincom sliding head lathes, initially on the main spindle and more recently on the sub-spindle. To enable this, the machine models are systematically being strengthened to withstand the rigours of the momentary air cutting that creates the chip-breaking effect. There will be five Cincom machines on show at MACH 2022 equipped with LFV. A pair of Citizen’s Miyano fixed-head lathes also benefit from the technology.
A total of 12 barfed, sliding and fixed head mill-turn centres will be demonstrated under power on the Citizen stand, including an automated production cell with integrated loading and unloading. Making its world debut will be the new, 20mm bar capacity Cincom L20-XIIB5LFV. The series-5 Cincom M32-VIIILFV will appear for the first time at MACH, as will the fixed head Miyano BNE‐65MYY. Both have been redesigned to offer more power and flexibility and have been fitted with the latest Mitsubishi 800-series touchscreen control.
On show for the first time will be a Cincom L32‐XLFV with integrated, high-speed laser cutting, a capability that was originally developed for efficient production of apertures in thin-wall stents on smaller sliding head lathes. There will be a Cincom D25-VIILFV exhibited for the first time at MACH with the proprietary chip-breaking software. As on many other sliding head lathes manufactured by Citizen, the user has the advantage of being able to remove the guide bush for more economical material usage when producing shorter components up to typically 2.5 times the bar diameter. A further highlight will be a Cincom A20‐VIILFV, the first to be equipped with multi-axis LFV software in a Fanuc-based Cincom control.
The exhibition will also feature the first UK showing of the 12mm bar capacity Cincom L12-XLFV with five rear-facing static and driven end-working tool positions and the addition of a Y-axis on the counter spindle to mirror the main spindle’s 3-axis movements.
From the Miyano stable, the ABX-64THY with 80mm bar capacity and an ANX-42SYYLFV with FANUC control will also make their debuts. Making another appearance at MACH to illustrate automated chucking will be the twin-spindle Miyano GN-3200W equipped with a high-speed loader capable of achieving high levels of productivity. The compact, rigid, thermally symmetrical machine offers a wide choice of infeed/outfeed devices, single or double high-speed gantry loaders, and transfer and turnover units.
Rounding off the exhibits on the stand will be an educational area explaining the latest Citizen software. It includes Eco Function hybrid technology that automatically saves energy through the intelligent use of power during non-cutting periods, underpinned by clear, on-screen graphical information showing present, maximum, cumulative and historical power consumption values. The next iteration of Alkart Wizard for off-line programming will also be in evidence, as well as Citizen’s Industry 4.0 capabilities encompassing the latest machine networking and monitoring functionality.
