Our best estimate for a swiss-type lathe in this class — not a quote from Citizen Machinery. Configuration moves it a long way.

Overview

The Citizen Cincom B12-VII is a 7-axis sliding-headstock lathe for 12 mm (0.472 in) bar, listed with a main spindle and a back spindle that both reach 15,000 RPM, and with LFV chip breaking as standard. The model is not in Citizen's current lineup, so it is a used-machine purchase, and the figures below are listed figures to be checked on the machine.

Matching spindle speeds are the useful detail here. Small diameters need high rpm to reach a sensible cutting speed, and with the back spindle as fast as the main one, back-end drilling, facing and small turned features are not slowed down while the main spindle waits. Power is low, 1.5 / 2.2 kW (2 / 3 HP) on the main spindle and 0.75 / 1.5 kW (1 / 2 HP) on the back, which is normal for this bar size but means light depths of cut in hard materials.

The guide bushing is the standard configuration and the listed machining length is 150 mm (5.91 in), so long, thin parts are supported close to the tool. LFV helps with materials that form long chips. The listed figures give no tool count, driven-tool speed or rapid rates, so the tool layout of any particular machine has to be checked in person.

The control is a Mitsubishi Meldas with Citizen software, and the machine weighs approx. 1,500 kg (3,307 lbs). The Cincom B12E-II, for comparison, runs to 12,000 rpm (R.G.B.8,000 rpm) and weighs 1,100 kg.

Strengths & Limitations

Strengths

Main and back spindles both listed at 15,000 RPM
LFV chip breaking listed as standard
150 mm (5.91 in) machining length from 12 mm (0.472 in) bar
7-axis simultaneous control on a Mitsubishi Meldas with Citizen software

Limitations

Main spindle motor of 1.5 / 2.2 kW (2 / 3 HP) suits light cuts only
No guide-bushless mode is listed; the guide bushing is the standard configuration
Not in Citizen's current lineup; listed figures need checking on the machine
The listed figures give no tool count or driven-tool data, so the tooling layout must be checked in person

Best For

Small-diameter turned parts from 12 mm bar Parts needing high spindle speed at both ends Materials that form long chips, using standard LFV

Frequently Asked Questions

01 How fast are the spindles on the Cincom B12-VII?

Both the main and back spindles are listed at 15,000 RPM. The main spindle motor is 1.5 / 2.2 kW (2 / 3 HP) and the back spindle motor 0.75 / 1.5 kW (1 / 2 HP).

02 Does the B12-VII have LFV chip breaking?

The listed figures give LFV chip breaking as standard. It helps on materials that form long, stringy chips. Check that it is enabled on any used machine before relying on it for unattended runs.

03 How does the B12-VII compare with the Cincom B12E-II?

The Cincom B12E-II runs to 12,000 rpm (R.G.B.8,000 rpm) and weighs 1,100 kg. The B12-VII is listed with 15,000 RPM on both spindles and approx. 1,500 kg (3,307 lbs), with a back spindle and LFV standard.

04 What should I confirm on a used B12-VII?

The tool count, the driven-tool layout and the rapid rates, none of which are listed. Also confirm the Mitsubishi Meldas control and its Citizen software, and plan for approx. 1,500 kg (3,307 lbs).
