Citizen Cincom L32-XII

The Citizen Cincom L32-XII extends the legendary L-series Swiss-type platform to 32mm bar capacity with a full 12-axis simultaneous configuration, addressing the segment of the precision market where parts exceed the 20mm diameter range but still demand Swiss-type precision, throughput, and complete machining capability. The L32-XII carries the same architectural philosophy as the L20-XII—simultaneous dual-spindle operation, comprehensive tooling, and LFV chip-breaking on both spindles—applied to the larger diameter range that aerospace structural components, hydraulic system fittings, medical orthopedic parts, and industrial precision components require.

At 32mm bar capacity, the L32-XII's main spindle power steps up appropriately: 3.7/5.5/7.5 kW across the continuous, 15-minute, and peak ratings, providing the torque required for aggressive turning and milling in large-diameter titanium, Inconel, and stainless steel workpieces. The back spindle operates at 10,000 RPM with 1.5/2.2/3.7 kW, matching the backworking power to the demands of secondary operations on 32mm parts. Main spindle maximum speed is 8,000 RPM, calibrated to the surface speed requirements of 32mm bar stock rather than the higher RPM of smaller-diameter platforms.

The 12-axis simultaneous configuration enables the same parallel front-work and backwork processing that makes the L20-XII the throughput reference in 20mm Swiss. For complex 32mm parts requiring extensive front-end machining plus comprehensive secondary operations, the L32-XII's simultaneous operation capability reduces cycle times dramatically compared to machines that must sequence operations between spindles. Up to 45 tool positions in a configurable gang-and-turret layout accommodate the complete tooling strategies that complex 32mm programs require.

LFV chip-breaking on the L32-XII is particularly critical at the 32mm diameter range, where the larger cross-section cuts produce the most substantial chips. Deep hole drilling and boring in titanium and Inconel at 32mm diameter demands reliable chip breaking to prevent tool damage and maintain dimensional accuracy in blind holes. Citizen's dual-spindle LFV implementation covers both concurrent operations, making lights-out production viable on difficult materials that would otherwise demand operator monitoring.

Machine footprint extends to approximately 2,450 x 1,650 x 1,850 mm at around 2,900 kg to accommodate the larger structural requirements of 32mm capacity. The Mitsubishi Meldas control handles full 12-axis simultaneous coordination, and guide-bushless configuration is available for short part families where bar remnant reduction matters.
