Citizen Cincom A32-VII

The Citizen Cincom A32-VII extends the A-series Swiss-type platform to 32mm bar capacity, covering the broader diameter range demanded by larger precision components in aerospace, medical, and industrial markets. Where the A20 series handles the high-volume 20mm-and-under segment, the A32-VII steps into territory occupied by larger fittings, valve bodies, complex connectors, and structural precision parts that start as 32mm bar stock. The 'VII' designation again signals the seventh generation of Citizen's accumulated refinement on this platform, incorporating LFV chip-breaking as a standard feature alongside the proven structural and axis architecture of the A-series.

The A32-VII's main spindle delivers 12,000 RPM with a stepped power curve reaching 3.7/5.5 kW, providing the torque needed for turning and milling 32mm-diameter components in challenging materials including stainless 316L, Inconel, and titanium alloys. The back spindle operates at 10,000 RPM maximum with 1.5/2.2 kW, handling secondary operations on the sub-spindle side including drilling, threading, and cross-drilling on backwork features. The machine accommodates up to 40 tool positions in a gang-and-turret layout suited for comprehensive machining of both ends of the part.

LFV chip-breaking on the A32-VII is particularly valuable at this diameter range, where larger cross-section cuts in difficult materials generate the most problematic chips. The ability to break chips mechanically during deep hole drilling and reaming in 32mm components dramatically reduces cycle time lost to chip clearing and enables reliable lights-out operation on part families that would otherwise demand operator monitoring. Citizen's synchronized LFV implementation works across the main spindle axes, covering the most demanding front-work operations.

The guide-bushless option on the A32-VII makes economic sense for many 32mm part families where bar remnant savings are more significant per pound of bar stock than on smaller diameters. The FANUC 32i-B control with Citizen's Swiss-type software manages axis synchronization, LFV parameter control, and guide bushing/guide-bushless switching. Machine footprint runs approximately 2,350 x 1,600 x 1,800 mm, fitting standard Swiss cell layouts while accommodating the larger chip management and coolant volumes associated with 32mm production.
