Tsugami M08JL8-II

The Tsugami M08JL8-II is an 8-station lathe built for long work, turning parts up to 800 mm (31.5 in) long. Bar capacity is 65 mm (2.56 in), and the maximum turning diameter is 280 mm (11.0 in) in an 8 in chuck.

Put beside the standard M08J-II, which has 290 mm (11.4 in) of turning length and weighs 3,300 kg (7,275 lb), the JL8 is a different class of machine for shaft work. Its bed takes parts nearly three times as long, and the machine grows to 4,000 kg (8,818 lb) on a footprint of 2,511 × 1,818 × 1,690 mm (98.9 × 71.6 × 66.5 in). Even the 12-station M08D-II, at 380 mm (15.0 in), reaches less than half of that length.

The spindle is the J-type unit: 9/11 kW, 4,000 rpm (rated 3,500 rpm), and a low-speed type limited to 1,500 rpm as an option. For long shafts the power is rarely the limit. Rigidity is. A part 800 mm long held only in the chuck will chatter and taper under any meaningful cut, and the spec table lists neither a tailstock nor a steady rest. Before ordering, establish with Tsugami what work support comes with the machine and what can be added.

Axis rapids are 24 m/min on X and 27 m/min on Z; on long Z moves the faster Z rate is the one that shortens cycles. Eight tool stations cover a straightforward shaft (turning, grooving, threading, centre drilling) but leave little room for spares. The table shows no Y axis and no driven-tool rating, so keyways and cross holes will need another machine unless Tsugami confirms an option.
