Citizen Cincom L32-IX

The Citizen Cincom L32-IX is a 32 mm sliding-headstock lathe with 8,000 rpm main and back spindles, a 39 mm spindle bore, a 320 mm guide-bush stroke and max. 36 tools. It is listed on Citizen's L32 page separately from the newer L32 generation of types VIII, X and XII, and it is the lighter machine of the two at 2,900 kg.

Its guide-bushless stroke is not a fixed figure. Citizen gives it as two and a half times the workpiece diameter per chucking, so the smaller the diameter, the shorter the part that can be cut without the guide bush. Large-diameter, short parts suit this mode; thin parts belong in guide-bush mode, where one chucking covers 320 mm.

Tooling is arranged around a gang tool post whose rotary tools drill 8 mm and tap M6 at up to 6,000 rpm on a 1.0 kW drive. An opposed tool post with its own rotary tools (8 mm drilling, M6 tapping, 6,000 rpm, 1.0 kW) is noted as an optional feature on all types, and the back tool post rotary tools are marked OP. As delivered in its basic form, then, back-end work is the back spindle's own drilling to 10 mm and tapping to M10. Front drilling reaches 12 mm with M12 cutting taps, and turning tools are 16 mm square.

The main spindle motor is listed at 3.7/7.5 kW and the back spindle motor at 2.2/3.7 kW. All axes rapid at 32 m/min. Against the Cincom L32-VIII, which offers a 38 mm option, max. 48 tools and a fixed 80 mm guide-bushless stroke on a 3,500 kg frame, the type IX is the smaller installation: 13.2 kVA rated and 6.9 kVA average under load, with a 1,050 mm centre height.
