DN Solutions PUMA 800 LY II

The DN Solutions PUMA 800 LY II is the long-bed, 32-inch chuck Y-axis variant of the 700/800 platform. It combines the massive clamping force of an 813 mm (32 in) chuck with Y-axis mill-turn capability and 3,200 mm (126 in) of turning length. When your workpieces are too big for a 24-inch chuck and need off-center milled features along a 3-meter length, this is the machine.

The spindle delivers 55 kW (74 hp) with 8,076 Nm (5,957 ft-lb) of torque at a max speed of 750 RPM. The 375 mm (14.8 in) spindle bore handles through-bore work on oversized tubular components. The 750 RPM ceiling is the trade-off for the 32-inch chuck — the larger, heavier rotating assembly requires reduced speed for bearing life and safe centrifugal forces. At the large diameters this machine handles, 750 RPM still delivers productive surface speeds.

The Y-axis provides 200 mm (8 in) of off-center travel. Combined with 3,000 RPM live tooling on the 12-station turret and C-axis control, the LY II can drill bolt patterns on large flanges, mill flats on heavy castings, cut keyways on oversized shafts, and tap holes on components weighing multiple tonnes. These operations would otherwise require crane-lifting parts to a horizontal boring mill — a process that takes hours and introduces positional errors.

Z-axis travel is 3,235 mm (127 in) with 470 mm (19 in) on X. Rapids are 12 m/min on X, 10 m/min on Z, and 6 m/min on Y. At 22,500 kg (49,604 lb), the machine matches the 700 LY II in weight, sitting on the same bed and frame. Box-way construction handles the extreme cutting forces.

The FANUC 0i-TF Plus control manages the multi-axis coordination. The PUMA 800 LY II serves a very specific segment: shops processing the largest-diameter parts that demand 32-inch chuck clamping with long-bed Y-axis mill-turn capability. Large pipe, heavy castings, and oversized forgings are its natural domain. Specs sourced from DN Solutions published data.
