The new Doosan Machine Tools NHP 4000 Horizontal Machining Center is Designed for rapid removal rates; the 400mm pallet NHP 4000 and 500mm pallet NHP 5000 machines come with a 15,000 rpm spindle standard, and up to 50 HP and Up to 1G acceleration/deceleration on X, Y and Z-axes, delivering productivity increases as high as 25% over the previous model.
In optimizing the construction of the machine, the footprint of the NHP has been reduced by 15% compared to the previous model, yet the machining area has been expanded by 24%. The center-through bed chip management evacuates large volumes of chips quickly for enhanced efficiency.
The new random access disc-type tool magazine allows high-speed 0.9 second tool-to-tool and 2.3 second chip-to-chip times. In addition to minimizing non-cutting time, this design also reduces vibration, resulting in more stable operation.
The pallets can accommodate loads of up to 400kg (880 lbs), for the NHP 4000 and up to 500kg (1100 lbs) for the NHP 5000, and both through-pallet and overhead hydraulic fixturing options are available. Additionally, the APC has been refined to achieve a 27% faster indexing time.
