What to Look for When Buying a Used Citizen
Citizen machines are precision instruments built for tight-tolerance, high-volume production. Whether you are evaluating a Cincom Swiss lathe or a Miyano turning center, thorough inspection protects your investment.
On Cincom Swiss lathes, inspect the guide bushing and sliding headstock. The guide bushing is the heart of any Swiss-type lathe. Check for wear marks, scoring, or uneven contact on the bushing bore. Measure bar stock runout at the guide bushing face and verify that the sliding headstock feeds smoothly across the full Z-axis stroke.
Test spindle condition and sub-spindle handoff. Measure main spindle runout at the collet face using a test indicator. On dual-spindle Cincom models, run the sub-spindle pickup sequence to verify accurate part transfer and synchronization. Listen for bearing noise at both low and high RPM.
Verify live tooling and gang slide function. Cincom and Miyano machines frequently include live (driven) tool stations for cross-drilling, milling, and polygon turning. Cycle every live tool position and check for excessive play or vibration. On gang-slide configurations, inspect the slide ways for wear and confirm tool positions repeat accurately.
Confirm control and software version. Citizen Cincom lathes use a proprietary CNC control built on Mitsubishi hardware, while Miyano turning centers typically run Fanuc or Mitsubishi controls. Verify the control boots cleanly, confirm the software version, and check that all axes home correctly. Older Cincom controls may have limited program memory; confirm capacity meets your needs.
Citizen Cincom Swiss-Type Lathes
L-Series (L12, L20, L32)
The Cincom L-series is Citizen's most widely traded Swiss lathe platform. The L12 handles bar stock up to 12 mm, the L20 covers up to 20 mm, and the L32 machines bar up to 32 mm diameter. All three models feature Citizen's gang-tool layout with multiple live tool stations, a programmable sub-spindle, and optional B-axis for off-center milling. The L20 is the most popular Citizen model on the used market.
A-Series and M-Series
The Cincom A20 is a compact Swiss lathe designed for straightforward 2-axis turning with a small footprint. The M-series (M16, M32) is built for complex, multi-axis Swiss machining with turret-style tool configurations instead of gang slides. M-series machines handle intricate milling, drilling, and polygon-turning operations common in aerospace and medical production.
D-Series and K-Series
The Cincom D25 is a mid-range Swiss lathe with a tool post configuration that balances flexibility and rigidity. The K-series (K12, K16) targets high-speed production of small-diameter parts such as watch components, electronic pins, and dental screws.
Citizen Miyano CNC Turning Centers
BNA Series
The Miyano BNA-42 is a compact, high-precision fixed-headstock turning center with dual spindles and a turret with live tooling. The BNA platform handles chucking work and short bar applications where Swiss-type operation is unnecessary. BNA machines are widely used in automotive and hydraulic component production.
BNE and BNJ Series
The BNE series (BNE-34, BNE-51) offers enhanced multi-axis capability with Y-axis cross milling and a sub-spindle for complete part processing in one setup. The BNJ series (BNJ-34, BNJ-42, BNJ-51) adds a second turret for simultaneous front and back machining, significantly reducing cycle times on complex parts. Both series use Fanuc controls and are production-proven in medical device and precision component manufacturing.
Legacy Miyano Models
Older Miyano turning centers, including the BNC, BND, and TSV series, remain reliable workhorses on the used market. These machines offer solid construction, Fanuc or Mitsubishi controls, and compact footprints. Parts and service support remain available through Citizen Machinery Americas.

Frequently Asked Questions About Used Citizen Machines
Are used Citizen machines reliable?
Yes. Citizen builds its machines to watchmaker-grade precision standards. Cincom Swiss lathes and Miyano turning centers are designed for round-the-clock production in demanding industries like medical devices and aerospace. With proper maintenance, used Citizen machines deliver years of accurate service.
What is the difference between Cincom and Miyano?
Cincom is Citizen's Swiss-type (sliding headstock) lathe brand, designed for long, slender parts machined through a guide bushing. Miyano is Citizen's fixed-headstock turning center brand, designed for chucking and short bar work. Citizen acquired Miyano in 2011 and markets both lines under the Citizen Machinery name.
What CNC control does Citizen use?
Cincom Swiss lathes use a proprietary Citizen CNC control built on Mitsubishi hardware. Miyano turning centers typically use Fanuc or Mitsubishi controls. The Cincom control includes Citizen-specific features like LFV (Low Frequency Vibration) cutting and Alkart Wizard programming software on newer models.
What should I inspect before buying a used Citizen?
Focus on guide bushing condition (on Swiss models), spindle runout, sub-spindle synchronization, live tooling function, and control software version. Cycle all axes, test the bar feeder interface, and check coolant and chip management systems. Request maintenance records when available.
What Citizen models hold their value best?
The Cincom L20 and L32 are the strongest performers on the resale market due to their versatility and widespread adoption. Miyano BNE and BNJ dual-spindle turning centers also hold value well because of their production efficiency. Call (844) 478-8181 for current valuations on any Citizen model.
What industries use Citizen machines?
Medical device manufacturing (bone screws, dental implants, surgical instruments) is the largest market for Cincom Swiss lathes. Automotive (fuel injector components, sensor housings), aerospace (fasteners, fittings), electronics (connector pins, contacts), and watchmaking also rely heavily on Citizen equipment.
