Our best estimate for the Citizen Cincom L20-XII is $200,000 - $320,000. This is an estimate for a swiss-type lathes in this class, not a quote from Citizen Machinery; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/citizen-cincom-l20-xii#price; the request is passed to Citizen Machinery or an authorised dealer.
The tooling layout on the gang tool post. The Cincom L20-X lists 25 gang rotary tools and 45 tools in total; the L20-XII lists 21 and 41. Back rotary tools, the Y2 axis, the drilling tool counts, spindle speeds and the 2,680 kg weight are the same in both columns.
Their spec columns on Citizen's series page are identical. Citizen describes the type XIIB5 as the model in the lineup that allows simultaneous 5-axis control, so that capability is what separates the two; the table itself shows no differing figure.
They drill up to 5 mm and tap up to M4 with cutting taps, at up to 7,500 rpm (rated 6,000 rpm), driven by a 0.75 kW motor. The Y2 axis moves them at a rapid rate of 8 m/min. The back spindle itself drills to 8 mm and taps to M8.
Turning tools are 12 mm square as standard, with 13 mm and 16 mm square listed as options. Sleeves are 25 mm (GDS107, 210) or 19.05 mm in diameter. Rotary tools and drill sleeves use ER11 and ER16 collet chucks.
