Citizen Cincom L32-XII

The Citizen Cincom L32-XII is a 32 mm Swiss-type automatic lathe (38 mm optional) from the current L32 generation, equipped for back-end machining with back rotary tools and a Y2 axis, and listed with max. 45 tools. Main and back spindles run to 8,000 rpm. Citizen launched this generation together with the L32XIIB5, the type capable of simultaneous 5-axis control.

Its tool count is the figure to question. The Cincom L32-X carries the same back rotary tools, Y2 axis, motors and 3,500 kg frame but lists max. 53 tools, and even the Cincom L32-VIII without back rotary tools lists max. 48. Citizen's column does not say what the type XII gains for the smaller count, so a buyer should get the tooling layout from Citizen and match it against the part before choosing it over the type X.

The working envelope is generous for this class. One chucking reaches 320 mm with the guide bush and 80 mm without it, the spindle bore is 39 mm, and front drilling goes to 12 mm with M12 taps. At the back, the spindle drills 10 mm and taps M10, while back rotary tools on the Y2 axis drill 8 mm and tap M6 at up to 6,000 rpm. The Y2 axis rapids at 24 m/min; the X1, X2, Y1, Z1 and Z2 axes at 32 m/min.

Spindle drive is listed as 5.5/7.5/7.5 kW at the front and 3.7/5.5 kW at the back. Gang rotary tools drill 10 mm and tap M8 at up to 6,000 rpm, rated 4,500 rpm, on a 1.0 kW motor. Turning tools are 16 mm square, 130 mm long. The machine is rated at 16.9 kVA and Citizen lists optional automation and labour-saving devices for the series.
