Estimated price range
Our best estimate for a swiss-type lathe in this class — not a quote from Citizen. Configuration moves it a long way.
Overview
The Citizen Cincom E16-VIII is a sliding-headstock automatic lathe for bar up to 16 mm (0.630 in), listed with 8-axis simultaneous control, a main spindle up to 15,000 rpm and a back spindle up to 12,000 rpm. It is not in Citizen's current lineup, so any machine on offer is used and each listed figure should be checked on the machine.
Speed is matched to the bar size. On a 16 mm bar, and more so on the small diameters cut from it, 15,000 rpm keeps surface speed up where a slower spindle would struggle. The motors are small, 2.2 kW (3.0 HP) on the main spindle and 1.5 kW (2.0 HP) on the back spindle, so heavy roughing in tough alloys will need lighter passes.
Driven tools are listed at front and back, at up to 8,000 rpm, with up to 20 tool positions in all. The machine runs with a guide bushing and the listed machining length is 150 mm (5.91 in), long enough for slender pins and shafts that need the bushing's support close to the cut. LFV chip breaking is listed as configuration dependent, so a particular machine may or may not have it.
The listed control is a Fanuc 32i, the footprint approx. 1,750 x 1,150 x 1,650 mm and the weight approx. 1,800 kg (3,969 lbs). Next to the Cincom B12E-II, which runs to 12,000 rpm (R.G.B.8,000 rpm) and weighs 1,100 kg, the E16-VIII is a faster and heavier machine with a back spindle.

Frequently Asked Questions
01
Parts from bar up to 16 mm (0.630 in) in diameter, with a listed machining length of 150 mm (5.91 in). The machine uses a guide bushing, which supports slender work close to the tool.
02
The main spindle is listed at up to 15,000 rpm on 2.2 kW (3.0 HP) and the back spindle at up to 12,000 rpm on 1.5 kW (2.0 HP). Driven tools, at front and back, run at up to 8,000 rpm.
03
LFV (Low Frequency Vibration) is listed as configuration dependent. On a used machine, confirm whether it was supplied before planning work in materials that produce long, stringy chips.
04
The Cincom B12E-II runs to 12,000 rpm (R.G.B.8,000 rpm) and weighs 1,100 kg. The E16-VIII is listed with a 15,000 rpm main spindle, a 12,000 rpm back spindle and approx. 1,800 kg (3,969 lbs).
