Doosan Machine Tools’ NHP Horizontal Machining Center series comes standard with a 15,000 rpm spindle with 40 horsepower and 169 foot-pounds of torque. For heavy cutting, a high-torque 15,000 rpm spindle with 223 foot-pounds is available, and a 20,000 rpm spindle is in development for customers with higher speed precision applications.

Up to 1G acceleration/deceleration on X, Y and Z-axes have increased productivity compared to the previous model. The random access disc-type tool magazine enables 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, the company says.

According to the company, the pallets can accommodate loads of up to 400 kg (880 lbs) for the NHP 4000 and up to 500 kg (1,100 lbs) for the NHP 5000, and both through-pallet and overhead hydraulic fixturing options are available.
