Citizen Cincom B16E-VI

The Citizen Cincom B16E-VI is the 16 mm sliding-headstock lathe in Citizen's B12E/B16E table that has everything the series offers: a 10,000 rpm main spindle, a 16 mm back spindle, gang rotary tools and 16 tool positions. It is the model to look at when 16 mm parts need side features and a machined back face in the same cycle.

Its rotary tools are rated the same as on the smaller Cincom B12E-VI: 5 mm drilling and M4 tapping at up to 4,500 rpm from a 0.5 kW tool spindle motor. On 16 mm stock that is enough for cross holes, wrench flats and small slots, though a milled feature in stainless or other tough material will be limited by the small drive rather than by the tool.

The back spindle chuck takes 16 mm, the spindle reaches 6,000 rpm on a 1.0 kW motor, and back machining is listed to 5 mm drilling and M3 tapping with 30 mm of the part protruding. Front drilling goes to 6 mm and tapping to M6. Stroke per chucking is 135 mm with the guide bush, or 60 mm with the R.G.B. in use, when the main spindle drops to a lower bracketed limit.

Within the series, the Cincom B16E-V has the same back spindle but no rotary tools and 13 positions, and the Cincom B16E-II has the rotary tools but no back spindle and 12 positions. The Cincom B12E-VI is the same layout for 12 mm bar with a 12,000 rpm spindle. The B16E-VI draws 5.2 kVA rated and 4 kVA on average and weighs 1,150 kg.
