Our best estimate for the Nakamura-Tome WT-250II is $300,000 - $475,000. This is an estimate for a cnc lathes / turning centers in this class, not a quote from Nakamura-Tome; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/nakamura-tome-wt-250ii#price; the request is passed to Nakamura-Tome or an authorised dealer.
The WT-250II turns up to 250 mm (9.8 in) in diameter and 555 mm (21.9 in) in length, with an 18.5/15 kW left spindle at 4,500 rpm and 65 mm (2.6 in) bar capacity. The WT-150II is listed at 190 mm (7.5 in) and 515 mm (20.3 in), with a 15/11 kW spindle at 5,000 rpm. The WT-250II is the choice for larger diameters and heavier cuts; the WT-150II spins faster.
The left spindle takes bar up to 65 mm (2.6 in). The right spindle takes 51 mm (2 in) as standard. With the Ø65 mm option the right spindle also passes 65 mm (2.6 in), but its top speed drops from 5,000 rpm to 4,500 rpm.
Left spindle: 18.5/15 kW standard, with an optional 35/26/22 kW motor or an optional wide-range 15/11 kW motor. Right spindle: 11/7.5 kW standard, with 15/11 kW and 18.5/15 kW listed as options. With both spindles synchronized the table gives 29.5 kW.
Yes, it has a 5.5/3.7 kW milling drive for driven tools on its upper and lower turrets, with up to 48 tools listed. The table gives no Y-axis stroke, so ask Nakamura-Tome whether the features you need off the spindle centreline can be reached before you commit.
The machine measures 4,059 × 2,314 × 2,225 mm (W × D × H). Add the length of any bar feeder behind the left spindle and room to open the doors and service the turrets when you plan the layout.
