Our best estimate for the Citizen Cincom R04-VI is $90,000 - $160,000. 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-vi#price; the request is passed to Citizen Machinery or an authorised dealer.
The Cincom R04-VI takes work up to 4 mm dia. and machines 40 mm with a fixed guide bushing or 30 mm with a rotary one. The Cincom R01-VI is limited to 1 mm dia. and 20 mm with either bushing, and its back chuck is 1 mm dia. against 4 mm dia. on the R04-VI. Both run 20,000 rpm spindles, mount 17 tools and weigh 1,100 kg.
The table gives 40 mm of machining length with the fixed guide bushing and 30 mm with the rotary guide bushing. If the parts are longer than 30 mm, the fixed bushing is the only way to keep them in one chucking; the rotary bushing is the choice when the bar itself makes a fixed bushing impractical.
M3 on the main spindle, using a tap or die, and M3 tapping in the back machining process. Gang rotary tools tap up to M2 at max. 8,000 rpm. Drilling capacities are 3 mm dia. at the front and back and 2 mm dia. with the rotary tools.
Turning tools have 8 mm Sq. shanks and the sleeve holders are 15.875 mm dia. Up to 17 tools can be mounted. Check any holders you already own against these sizes before planning the first jobs.
