Technical Description

The Doosan PUMA 280L is a 2-axis horizontal CNC turning center from the PUMA 280 series, in the long-bed version without live tooling. It uses a belt-driven A2-8 spindle and a 10-station servo-driven turret, and was offered with a Fanuc 0i-TC or 21i-TB control. Swing over the bed is 630 mm, with 500 mm over the saddle. Maximum turning diameter is 420 mm (16.5 in) and maximum turning length is 1,078 mm (42.4 in). Bar working capacity is 76 mm (3.0 in). The main spindle runs to 3,500 rpm with an A2-8 spindle nose and an 86 mm (3.4 in) through hole, driven by a 22 kW (29.5 hp, 30-minute rating) motor. Axis travels are 242 mm in X and 1,100 mm in Z, with rapid traverse of 20 m/min in X and 24 m/min in Z. The 10-station turret takes 25 x 25 mm OD tools and 50 mm boring bars and indexes in 0.15 seconds. A manual tailstock with a 100 mm quill, MT#5 taper and 100 mm quill travel is standard. The machine occupies 3,838 x 1,670 mm (151.1 x 65.7 in) with a height of 1,735 mm (68.3 in) and weighs 5,300 kg (11,684 lb).
