USED CITIZEN A20 TYPE VII – 2012

The CITIZEN A20 Type VII is a compact 5-axis CNC Swiss-type sliding-headstock automatic lathe designed for high-volume precision production of small-diameter components. Manufactured by Citizen Machinery, the A20VII is built around a maximum machining diameter of 20 mm, with guide-bushing machining capability up to 200 mm in length. It can also operate in guide-bushing-less mode for shorter parts.

The 2012 A20VII is particularly useful for manufacturers producing small, intricate components where multiple turning, drilling, tapping, and cross-machining operations need to be completed automatically. A documented 2012 Citizen A20VII 2F7PL is equipped with a FANUC 32i CNC control, 8,000 RPM main spindle, 6,000 RPM rotary tooling, 21 tool positions, and live back-working tools.

The machine provides a 20 mm maximum machining diameter, 10 mm maximum front drilling diameter, M8 front tapping capacity, 7 mm rotary-tool drilling capacity, M6 rotary-tool tapping capacity, and an 8,000 RPM back spindle. Citizen’s specifications also show rapid traverse rates of up to 32 m/min on X2, Y, Z1, and Z2 axes.

INDUSTRIES THAT USE CITIZEN A20 TYPE VII

The CITIZEN A20 TYPE VII is particularly suited to industries requiring high-volume production of small precision components.

Typical industries include medical, automotive, electronics, aerospace, instrumentation, electrical, hydraulic, precision engineering, and general contract manufacturing.

Its sliding-headstock architecture provides excellent support for small-diameter material, while the back spindle allows components to be transferred automatically for secondary operations.

This makes the A20VII particularly useful when manufacturers want to complete several operations in one automated cycle rather than transferring small parts between multiple machines.

---

TYPICAL PARTS CITIZEN A20 TYPE VII CAN PRODUCE

The A20VII can produce:

• Medical components
• Bone screws and orthopedic components
• Automotive pins
• Shafts
• Precision bushings
• Small fittings
• Connectors
• Electronic components
• Instrument components
• Threaded pins
• Small valve components
• Hydraulic fittings
• Precision fasteners
• Small aerospace components
• Micro-machined industrial components

Typical operations include turning, facing, grooving, threading, drilling, tapping, cross drilling, back drilling, boring, chamfering, and secondary-end machining.

WHY CHOOSE CITIZEN A20 TYPE VII

The primary advantage of the CITIZEN A20 TYPE VII is its ability to produce small, complex parts with multiple operations in a single automated cycle.

The machine provides 5-axis capability, a main spindle capable of up to 10,000 RPM, an 8,000 RPM back spindle, 21 tool positions, and guide-bushing machining up to 200 mm.

The back spindle is especially useful for completing secondary operations without removing the component from the machine. This can reduce handling, improve consistency, and shorten cycle times.

The A20VII can also operate without a guide bushing for shorter parts, providing additional production flexibility. Citizen identifies guide-bushing-less machining up to 2.5D, with a maximum of 55 mm.

For shops producing large quantities of small precision components, the A20VII can provide excellent productivity in a relatively compact machine footprint.

WHY BUY USED CITIZEN A20 TYPE VII

Buying a used CITIZEN A20 TYPE VII can be an economical way for a manufacturer to add Swiss-style CNC production capacity without purchasing a new machine.

The A20VII’s combination of 5-axis machining, main and back spindle operation, 21 tool positions, high spindle speeds, and automatic bar feeding capability makes it well suited to unattended or high-volume production.

A documented 2012 machine includes a FANUC 32i control, Edge Technologies C-320 magazine bar feeder, Cool Blaster high-pressure coolant, mist collector, and tooling, demonstrating how a used A20VII can be configured as a complete production cell.

When evaluating a used A20VII, buyers should inspect the main spindle, back spindle, guide bushing, spindle bearings, gang tooling, cross-working tools, X/Y/Z axis positioning, ballscrews, coolant system, bar feeder, FANUC control, lubrication system, and machine geometry.

For Swiss machines, it is especially important to check guide-bushing condition and alignment, because these directly affect the support of small-diameter bar stock and the quality of finished parts.

HOW MUCH DOES A USED CITIZEN A20 TYPE VII COST?

Used pricing for the CITIZEN A20 TYPE VII varies according to year, machine hours, spindle condition, control, bar feeder, tooling, guide-bushing equipment, high-pressure coolant, and overall production condition.

A documented 2012 Citizen A20VII 2F7PL has been sold and was equipped with a FANUC 32i control, Cool Blaster 850 mist collector, Edge Technologies C-320 magazine bar feeder, lubrication system, and tooling. The listing does not publish a final transaction price.

Another 2012 A20VII listing includes a FANUC 32i, Cool Blaster CB510 high-pressure coolant system, C-320 magazine bar feed, and tooling, also with pricing available by quote.

Based on the used market for this class of Citizen Swiss machine, I would use the following practical estimates:

USED CITIZEN A20 TYPE VII PRICE RANGE	ESTIMATED COST
As-Is / High-Hour / Needs Work	$25,000 – $40,000
Functional Used Machine	$40,000 – $55,000
Good Condition / Production Ready	$55,000 – $70,000
Excellent Condition / Well Equipped	$70,000 – $85,000+

For a 2012 CITIZEN A20 TYPE VII in good working condition, a reasonable estimated used-market value is approximately $45,000–$70,000 USD.

A machine with a FANUC 32i control, automatic bar feeder, high-pressure coolant, mist collector, good tooling package, and documented maintenance would generally fall toward the upper portion of that range.

For your inventory listing, I would use $50,000–$70,000 USD as a practical estimated asking-price range for a clean, operational 2012 A20VII with a bar feeder and production accessories.

The exact value should be adjusted based on power-on hours, cutting hours, guide-bushing condition, spindle condition, bar feeder, tooling, coolant package, and whether the machine can be demonstrated under power.
