USED CITIZEN A20VI – 2009
The 2009 CITIZEN A20VI is a precision CNC Swiss-type sliding headstock lathe designed for high-volume production of small-diameter, high-precision components. Manufactured by Citizen Machinery, the A20VI is built around a compact 20 mm machining capacity and combines sliding-headstock turning, C-axis machining, live tooling, and a sub-spindle within a single production platform. This configuration allows manufacturers to perform turning, drilling, tapping, milling, and rear-end machining operations with minimal workpiece handling. The machine is particularly suited for manufacturers producing small precision components in large quantities where repeatability, cycle-time efficiency, and automated production are important.
The A20VI provides a maximum machining diameter of approximately 20 mm and a maximum machining length of approximately 165 mm per chucking on documented 2009 configurations. Its compact machining envelope is specifically optimized for small-diameter components rather than large conventional turning applications. The sliding-headstock design supports the workpiece close to the cutting tools, helping provide stability when machining long, slender components that could otherwise be difficult to support using a conventional fixed-headstock lathe.

One of the machine’s primary advantages is its ability to combine multiple machining processes within a compact Swiss-type platform. The A20VI can perform conventional turning operations along with front-end drilling, live-tool cross machining, tapping, and rear-end operations using its sub-spindle. This reduces the need to transfer small components between separate machines and can improve dimensional consistency between multiple features.
The main spindle on documented A20VI configurations operates at up to approximately 8,000 RPM, while the back spindle can also reach approximately 8,000 RPM. Some A20-family specifications identify configurations capable of up to 10,000 RPM, so the exact spindle rating should be verified against the individual 2009 machine and its original specification. The high spindle speed is particularly useful for machining small-diameter components where higher rotational speeds can support efficient cutting and improved surface finishes. (machinetools.com)
The A20VI uses full C-axis indexing on both the main and back spindles, with documented specifications identifying approximately 0.001-degree indexing capability. This allows precise spindle positioning for milling, drilling, cross-hole machining, and other operations requiring controlled angular orientation. (machinetools.com)
The machine’s live tooling system further expands its machining flexibility. Documented A20VI configurations provide multiple live-tool positions on the main slide, with rotary tooling speeds of approximately 6,000 RPM. This allows manufacturers to perform cross milling, drilling, tapping, and related secondary operations without moving the workpiece to another machine. (toolquipusa.com)
The sub-spindle is another important component of the A20VI’s production capability. With a maximum back-spindle chucking diameter of approximately 20 mm and speeds up to approximately 8,000 RPM, the sub-spindle can grip the workpiece for rear-end machining operations. This enables manufacturers to complete front and back features within one automated production cycle.
The machine is capable of machining a wide variety of small-diameter materials including stainless steel, carbon steel, aluminum, brass, bronze, titanium, medical alloys, engineering plastics, and other precision materials. Proper tooling, cutting parameters, coolant delivery, and material-specific machining strategies remain important for achieving optimal results.
The A20VI is particularly well suited for manufacturing components such as miniature shafts, pins, connectors, fittings, bushings, medical components, electronic hardware, precision fasteners, valve components, and small mechanical assemblies. Its Swiss-type architecture is especially valuable when producing long or slender components where close tool support is required.
Many used 2009 A20VI machines are equipped with production accessories such as magazine bar feeders, chip conveyors, parts catchers, coolant systems, mist collectors, high-pressure coolant systems, and automatic fire-suppression equipment. Documented 2009 machines have been offered with Edge Technologies C-320 magazine bar feeders, chip conveyors, parts catchers, high-pressure coolant, and mist collection systems. (machinetools.com)
The machine can also support automated bar-fed production, making it especially useful for high-volume manufacturing environments. A long magazine bar feeder can supply material continuously, allowing the machine to produce large quantities of small components with limited operator intervention.
The A20VI’s compact footprint is another advantage for manufacturers with limited floor space. Despite its relatively small physical size, the machine integrates multiple machining functions, allowing a single production cell to perform operations that might otherwise require several conventional machines.
The CNC control system on documented 2009 machines is commonly FANUC-based, with some machines equipped with Citizen Cincom control configurations depending on market and machine specification. Buyers should verify the exact control installed on the individual machine before purchase. (machinetools.com)
The A20VI is especially attractive for manufacturers producing repetitive small components where cycle time, automation, and dimensional repeatability are important. Its combination of sliding-headstock machining, live tooling, C-axis capability, and sub-spindle functionality provides considerable flexibility within a relatively compact machine platform.
Industries including medical manufacturing, electronics, aerospace, automotive, telecommunications, hydraulic equipment, instrumentation, and precision contract machining can utilize the A20VI for producing small, complex components.
Because of its precision-oriented Swiss-type architecture, automated production capability, live tooling, sub-spindle, and compact 20 mm machining capacity, the 2009 CITIZEN A20VI remains a useful used CNC Swiss lathe for manufacturers requiring efficient small-part production.
