Our best estimate for the Citizen Cincom A20-VII is $150,000 - $230,000. 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-a20-vii#price; the request is passed to Citizen Machinery or an authorised dealer.
Yes. Guide-bushless, the maximum machining length is 2.5D, max. 55 mm. With the guide bushing it is 200 mm. The guide-bushless mode suits short parts; the guide bushing is for long, slender work.
On the main spindle, drilling to 10 mm dia. and tapping to M8. Gang rotary tools drill to 7 mm dia. and tap to M6. In back machining, drilling to 8 mm dia. and tapping to M6.
It chucks work up to 20 mm dia. with up to 50 mm of protrusion, and runs to max. 8,000 rpm on a 1.1/1.5 kW motor. Back-end drilling goes to 8 mm dia. and tapping to M6.
The Cincom B12E-II runs to 12,000 rpm (R.G.B.8,000 rpm) and weighs 1,100 kg. The A20-VII runs to max. 10,000 rpm, handles 20 mm dia. work, carries 21 tools and weighs 2,200 kg.
Citizen gives a power requirement of 7.1 kVA, with 4.1 kVA average during load operation. The centre height is 1,050 mm, which the bar feeder must match, and the machine weighs 2,200 kg.
