Our best estimate for the Citizen Cincom D25-VIII is $160,000 - $250,000. 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-d25-viii#price; the request is passed to Citizen Machinery or an authorised dealer.
Citizen's table shows the same figures for both except the tool count: 43 on the D25-VIII and 59 on the Cincom D25-VII. The table does not describe what the VIII's layout adds, so request the tooling layout drawings for both types and compare them against your part list.
It takes a 25 mm chuck, runs to 10,000 rpm and is driven by a 2.2/3.7 kW motor. Back machining is listed to 12 mm drilling and M10 tapping with up to 50 mm of the part protruding, and a separate 1.0 kW motor drives rotary tools on the back tool post.
The gang rotary tools run to 9,000 rpm on a 2.2 kW tool spindle motor, with a maximum drilling diameter of 10 mm and cut tapping to M8. The main spindle itself drills to 12 mm and cut-taps M10 at the front.
Citizen gives a 13 kVA power requirement and a 7.1 kVA average during load operation. The machine weighs 3,450 kg with a 1,050 mm centre height, so check floor loading and the electrical feed before delivery.
