Our best estimate for the Citizen Cincom B12 is $60,000 - $110,000. 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-b12#price; the request is passed to Citizen Machinery or an authorised dealer.
12 mm (0.472 in), through a 20 mm (0.787 in) spindle bore. With the guide bushing the machining length is 135 mm per chucking; with the removable guide bushing in use it is 60 mm per chucking.
The R.G.B. option lets the B12 run without a guide bushing for short parts. The per-chucking stroke drops from 135 mm to 60 mm, so it suits short, stubby work rather than long slender parts.
The main spindle drills to 6 mm and taps to M6. Gang rotary tools drill to 5 mm and tap to M4, running at 4,500 rpm on a 0.5 kW tool-spindle motor.
Confirm the top spindle speed, the number of tools and the machining diameter on the machine, since the table gives two values for each. The control is a Mitsubishi Meldas with Citizen software; power is 5.2 kVA rated and the weight 1,150 kg.
