Our best estimate for the Citizen Cincom L20 Type XII B5 is $250,000 - $400,000. 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-b5#price; the request is passed to Citizen Machinery or an authorised dealer.
Citizen describes the type XIIB5 as the L20 model that allows simultaneous 5-axis control. The spec columns of the two are otherwise identical: 41 tools, 21 gang rotary tools, the same Y2 axis and back rotary tools, 10,000 rpm spindles and 2,680 kg. Ask Citizen for the details of the 5-axis equipment, because the table does not list them.
20 mm as standard and 25 mm (1 in) as an option, through a 26.4 mm spindle bore. The 25 mm specification uses FC071-M collets and the FG521-M guide bushing. In that specification the guide-bush stroke is 188 mm per chucking instead of 200 mm.
The front spindle drive is rated 2.2/3.7/5.5 kW (continuous/15 minute/10%ED). The back spindle drive is rated 1.5/2.2/3.7 kW (continuous/40%ED/10%ED). Both spindles reach 10,000 rpm. Gang rotary tools use a 1.0 kW motor, or 2.2 kW with the S3 high-power specification.
AC 200V ±10% with a 60 A main breaker; rated consumption is 8.3 kVA and total load current 37 A, or 41 A with the S3 motor. Air must be supplied at 0.5 MPa. The machine weighs 2,680 kg and measures W2,222 × D1,265 × H1,835 mm, with a 1,050 mm centre height.
