Tsugami M08J-II

The Tsugami M08J-II is the compact 8 in chuck lathe of the M08 line, with 65 mm (2.56 in) bar capacity, a 280 mm (11.0 in) maximum turning diameter, 290 mm (11.4 in) of turning length and an 8-station turret. Its spindle is set up differently from the rest of the family: 9/11 kW, a maximum of 4,000 rpm (rated 3,500 rpm), and an optional low-speed type that tops out at 1,500 rpm.

That spindle is the reason to look at this model. The 12-station M08D-II runs faster, to 4,500 rpm, but on 7.5/11 kW. The M08J-II gives up some top speed for a higher first power figure, which suits roughing large-diameter bar and chucked blanks in steel, where surface speed limits the rpm long before 4,000 is reached. The low-speed option goes further in that direction; the table gives no torque figure for either type, so ask Tsugami what the 1,500 rpm version delivers at the chuck before choosing it.

In every other respect the J is the short, light member of the range. It weighs 3,300 kg (7,275 lb) on a footprint of 1,865 × 1,673 × 1,600 mm (73.4 × 65.9 × 63.0 in), where the M08D-II weighs 4,700 kg (10,362 lb). Rapids are 24 m/min on X and 27 m/min on Z.

The limits are the 8 stations and the 290 mm turning length. Parts that need more tools or more length point to the M08D-II, which offers 12 stations and 380 mm (15.0 in), or to the M08JL5-II, which keeps the J spindle and turret but extends turning length to 500 mm (19.7 in). The table lists no Y axis or driven-tool figures.
