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 B16 is a 16 mm-class sliding-headstock automatic lathe that is not in Citizen's current lineup under this name. The page Citizen keeps for the series lists the B16E-II, B16E-V and B16E-VI instead, so a B16 today is most likely a used machine, and its table has to be read with care.

The table on this page carries two sets of values that do not agree. Citizen's own row wording gives a maximum machining diameter of 16 mm, a back spindle chuck of 16 mm and a main spindle maximum of 10,000 rpm. Other rows give a 12 mm bar capacity, a 12 mm back spindle chuck and 12,000 rpm, which are the figures of the 12 mm machine. On a used B16, check the nameplate, the guide bush and the collets before relying on either set.

Where the rows agree, they describe a machine with both a back spindle and gang rotary tools. The main spindle through-hole is 20 mm, and the stroke is 135 mm per chucking, or 60 mm per chucking with the R.G.B. in use. Front drilling goes to 6 mm and tapping to M6. The gang rotary tools drill 5 mm and tap M4 at 4,500 rpm from a 0.5 kW motor, and back machining is listed to 5 mm drilling and M3 tapping with 30 mm of work protruding. Up to 16 tools can be mounted.

The main spindle motor is listed at 2.2/3.7 kW and the back spindle motor at 1.0 kW, with rapids of 21 m/min on X and Y and 15 m/min on Z. The machine weighs 1,150 kg and draws 5.2 kVA rated, 4 kVA on average in operation.

Strengths & Limitations

Strengths

Back spindle and gang rotary tools in one machine, with up to 16 tools mounted
Gang rotary tools rated for 5 mm drilling and M4 tapping at 4,500 rpm
135 mm per chucking with the guide bush, 60 mm per chucking with the R.G.B. in use
Light machine at 1,150 kg with a 5.2 kVA power requirement

Limitations

Citizen no longer lists the B16 under this name, so it is a used-machine purchase
The table gives both 12 mm and 16 mm for bar capacity and both 10,000 rpm and 12,000 rpm for the main spindle; confirm which applies to a given machine
Back machining is limited to 5 mm drilling and M3 tapping
The 0.5 kW tool spindle motor keeps rotary-tool work light

Best For

Small turned parts with cross holes on a used-machine budget Parts needing back-end drilling to 5 mm or M3 tapping Short parts run with the R.G.B. to reduce remnant

Frequently Asked Questions

01 Is the Cincom B16 still in Citizen's lineup?

Not under this name. Citizen's B12E/B16E series page lists the B16E-II, B16E-V and B16E-VI rather than a plain B16, so a B16 on the market today is a used machine. Check its serial plate and documentation to see which table it was built to.

02 Is the B16's bar capacity 12 mm or 16 mm?

The table on this page lists both. Citizen's own row wording gives a maximum machining diameter of 16 mm and a 16 mm back spindle chuck, while other rows give 12 mm for both. The 12 mm values match the 12 mm machine, so treat 16 mm as the likely figure but confirm it on the machine's guide bush and collets.

03 What rotary tooling does the B16 have?

The table lists gang rotary tools rated for 5 mm drilling and M4 tapping at 4,500 rpm, driven by a 0.5 kW tool spindle motor. Up to 16 tools can be mounted in total, against 13 to 16 in one of the summary rows.

04 What does the B16 need for power and floor loading?

The table gives a rated power consumption of 5.2 kVA and an average of 4 kVA during load operation. The machine weighs 1,150 kg and has a centre height of 1,000 mm. Motors are listed at 2.2/3.7 kW for the main spindle, 1.0 kW for the back spindle and 0.18 kW for coolant.
