Citizen Cincom M32

The Citizen Cincom M32 is the largest and most powerful machine in Citizen's Swiss-type Cincom lineup, handling bar stock up to 32mm standard diameter with a 38mm oversize option. Like its smaller sibling the M16, the M32 carries Citizen's M-series designation for maximum versatility, combining gang tools, a 10-station turret, and a back tool post to handle the widest possible range of part geometries within its capacity envelope. For shops producing precision components in the 20-38mm range—hydraulic fittings, automotive valve bodies, medical implants, and aerospace fasteners—the M32 is Citizen's answer to parts that exceed the L20's 20mm ceiling.

The M32's dual spindles both reach 8,000 RPM with substantial 5.5/7.5 kW power ratings, delivering the torque required for aggressive cuts in stainless steel, titanium, and hardened alloys at larger diameters where cutting forces increase significantly. The front spindle uses an FC081-M collet (FC251-M for 38mm) while the back spindle uses an FC081-M-K collet for secure workholding during secondary operations. Maximum machining length reaches 320mm per chucking—the longest in the Cincom range—enabling production of extended-length parts that smaller Swiss machines cannot handle.

The M32's tooling architecture is comprehensive. Gang rotary tools operate at 9,000 RPM, while turret rotary tools and back rotary tools reach 6,000 RPM across the 10-station turret and back tool post. Available in M32-V and M32-VII configurations, with 25-31 tool positions depending on setup, the machine handles complex multi-feature parts requiring turning, milling, cross-drilling, and complete backworking. The M32-VIII variant adds a programmable B-axis for 5-axis contouring on both main and sub-spindle, enabling compound-angle features that push the M32 into mill-turn territory.

Citizen's LFV chip-breaking technology is standard on the M32, and at 32mm diameter this feature becomes absolutely critical. Chip management at larger bar sizes is one of the biggest challenges in Swiss-type production, and LFV provides the controlled chip breaking that makes unattended production viable in stainless steel and titanium. The machine measures 2,860 x 1,465 x 1,900 mm and weighs 4,250-4,300 kg with 24 kVA rated power consumption and 79A full-load current. For shops that need the largest Swiss-type platform Citizen builds, the M32 represents the pinnacle of sliding headstock versatility.
