Our best estimate for the Citizen Cincom L20-X is $220,000 - $340,000. 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-x#price; the request is passed to Citizen Machinery or an authorised dealer.
A Y2 axis rapiding at 8 m/min, back rotary tools that drill 5 mm and tap M4 at up to 7,500 rpm, 6 front drilling tools instead of 3 and 8 back drilling tools instead of 4. The total rises from 38 tools on the Cincom L20-VIII to 45, and the weight from its 2,630 kg to 2,680 kg.
The Cincom L20-XII column shows the same back rotary tools, Y2 axis and drilling tool counts, but 21 rotary tools on the gang tool post and 41 tools in total. The L20-X keeps 25 gang rotary positions and holds 45 tools. Both weigh 2,680 kg.
Gang tool post rotary tools run at up to 6,000 rpm (rated 4,500 rpm) on a 1.0 kW motor, or 9,000 rpm on 2.2 kW with the S3 high-power specification. Back rotary tools run at up to 7,500 rpm (rated 6,000 rpm) on a 0.75 kW motor.
20 mm bar as standard, 25 mm (1 in) as an option. With the guide bush the stroke is 200 mm per chucking, or 188 mm in the 25 mm specification; without it, 50 mm per chucking. Parts up to 130 mm long can be ejected, and up to 40 mm of the part can protrude from the back spindle.
AC 200V ±10% with a 60 A main breaker. Rated power consumption is 8.3 kVA and the average under load is 4.5 kVA. Total load current is 37 A, or 41 A with the S3 high-power motor. Air is required at 0.5 MPa.
