Our best estimate for the Doosan Puma 3100B is $140,000 - $200,000. This is an estimate for a cnc lathes / turning centers in this class, not a quote from Doosan Machine Tools; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/doosan-puma-3100b#price; the request is passed to Doosan Machine Tools or an authorised dealer.
The chuck is 12 in on an A2-8 spindle nose and the bar capacity is 82 mm (3.2 in). Spindle bore is listed as 91 mm (3.58 in), and a separate through-hole row gives ⌀103 mm (4.1 in), so measure the draw tube on the machine if the bar size is close to the limit.
The table is not consistent. One pair of rows gives 3,500 RPM and 26 kW (34.8 hp); another gives 2800 rpm and 22 kW (30 Hp). Torque is listed once, at 1123 Nm (828 ft-lbs). Use the lower speed and power for planning until the machine's plate confirms the higher ones.
Live tooling is listed as an option, with a maximum of 5,000 RPM and 3.7 kW (5 hp). That is enough for cross-drilling, tapping and light milling. Because it is optional, check whether the machine being offered has a driven-tool turret.
Electrical supply is listed as 220/380 VAC 3-phase at 70 A. The machine is 4095 mm (161 in.) long, 1978 mm (78 in.) wide and 2010 mm (80 in.) high, weighs 5850 kg (13000 lbs.) and has a 350 L (92 gal) coolant tank.
Two sets of rows are listed. One gives 310 mm (12.2 in) in X and 920 mm (36.2 in) in Z; the other gives 293 mm (11.5 in) and 830 mm (32.7 in). Maximum turning length is 760 mm (29.9 in) in the one row that states it.
