2007 DOOSAN PUMA 280 CNC LATHES

Technical Description

The Doosan PUMA 280 is a two-axis CNC slant-bed turning center built by Doosan in the mid-2000s. It belongs to the PUMA 280 series, which also includes the 280L long-bed version, the 280M milling version with driven tools and C-axis, and the 280LM long-bed milling version. The base PUMA 280 is a turning-only machine with a single main spindle and no sub-spindle. Maximum turning diameter is 410 mm (16.14 in). The main spindle runs to 3,500 rpm and is driven by a 22 kW (29.5 hp) main motor, which gives the torque needed for heavier chucking and shaft work than the smaller PUMA 240 series. Tooling is held on a 12-station turret. Machines in the series were fitted with Fanuc CNC controls, and the exact control model varies from one build year to another. The PUMA 280 is used in job shops and production cells for flanges, hubs, shafts and other medium-size turned parts in steel and cast iron. Doosan later replaced the PUMA 280 series with the PUMA 2600 and PUMA 3100 turning centers, which cover the same 10-inch and 12-inch chuck classes.
