Tsugami B0326

The Tsugami B0326 is a 6-axis Swiss-type lathe for 32 mm (1.26 in) bar, with 330 mm (12.99 in) of machining length per chucking and tool stations listed as 32/42, of which 15/26 are driven. The control is a FANUC 32i-B.

Main and sub spindles share a range of 200 - 8,000 RPM, and the live tools run at 200 - 6,000 RPM. At 8,000 RPM a 32 mm bar is already at a high surface speed, so the cap matters mostly on the small diameters of stepped parts. The 6,000 RPM live-tool ceiling is the figure to watch for small drills and end mills.

Tsugami America gives the tooling as two pairs, 32/42 stations and 15/26 driven, without explaining what separates the figures. Confirm which configuration a quoted machine carries. Either way the driven count is high, which suits parts with many cross holes, flats and milled features on both ends. The machine runs with a guide bushing or in chucker mode, though no chucker-mode length is listed.

The B0326 weighs 4,000 kg (8,818 lb) and occupies 2,628 × 1,280 × 1,970 mm (103.5 × 50.4 × 77.5 in). The B0386 is the next capacity, at 38 mm (1.5 in) with 320 mm (12.6 in) of stroke and 4,850 kg (10,694 lb), and the B0266 sits below at up to 26 mm. Spindle motor power is not given in the B0326 table, so ask for it before comparing cutting capacity.
