CNC Swiss Lathes

Used Citizen Cincom B12: Sell or Buy at Auction

Citizen is a world-leading manufacturer of CNC Swiss-type automatic lathes: precision turning machines used for high-volume production of small, complex parts. Citizen Swiss lathes are ubiquitous in medical device manufacturing, aerospace fasteners, dental implants, and electronics components. The Cincom series is the industry standard for Swiss-type turning.

The Citizen Cincom B12 is a CNC Swiss-type automatic lathe with a 12 mm maximum bar capacity and a main spindle that turns up to 12,000 rpm, sized for high-volume small-diameter production rather than heavy bar work. It runs with a guide bushing for long, slender parts and converts to guide-bushing-less operation for shorter work, which trims bar remnant and material cost. Sub-spindle-equipped versions add a back spindle for complete back-working, and rotary live tools handle cross-drilling and secondary milling of up to roughly 5 mm within the same cycle, so a finished part can come off the machine in a single setup. That combination makes the B12 a workhorse for shops turning micro medical components, electronic connector pins, and small precision fasteners, where part complexity and repeatable cycle time matter more than raw bar size. Buyers at auction tend to be precision job shops and contract manufacturers already running Swiss-type production who want to add small-part spindle capacity without the lead time or cost of a new machine, and KD Auctions puts these listings in front of a base of 500,000+ industry contacts concentrated in medical device and electronics machining. Complete units sold with the guide bushing, sub-spindle tooling, bar feeder, and collet packages draw the strongest bidding, since a fully tooled B12 can be back in production almost as soon as it is uncrated.
