Our best estimate for the Citizen Cincom R04 is $80,000 - $150,000. 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-r04#price; the request is passed to Citizen Machinery or an authorised dealer.
The Cincom R04 back spindle is listed at 10,000 rpm and the machine at 950 kg (2,094 lb). The Cincom R04-VI lists max. 20,000 rpm on the back spindle and weighs 1,100 kg. Both handle work up to 4 mm dia. and run the main spindle to 20,000 rpm. The R04-VI is the model in Citizen's current lineup.
Rotary tools run to 8,000 rpm and are listed for 2 mm dia. drilling and M2 tapping. That covers small cross holes and threads on a 4 mm part; larger holes have to be drilled on the spindle centreline, where the front limit is 3 mm (0.118 in).
The table is not consistent on this: one row gives 13 tools and another 17. Count the holders on the machine you are looking at rather than relying on either figure.
Up to 4 mm (0.16 in) in diameter and 40 mm (1.57 in) in length. On the back spindle the chuck takes up to 4 mm (0.157 in) and the part may protrude up to 10 mm (0.394 in).
