The Doosan NHP 8000 is a high-performance horizontal machining center (HMC) designed for a variety of demanding applications. It combines heavy-duty cutting capabilities with high-speed machining and exceptional precision. Here's a closer look at its features and specifications:
Features:
- Power and Speed: The NHP 8000 boasts a powerful built-in spindle motor with a dual-wound "virtual gearbox" design. This translates to high torque at low rpm for efficient roughing cuts, along with a 10,000 rpm spindle speed for high-speed machining.
- Large Tool Capacity: The NHP 8000 utilizes a CAT50 BIG PLUS spindle taper, offering superior tool diameter, length, and weight capacity. This allows for handling a wider range of complex tooling tasks.
- Rigidity and Accuracy: The NHP 8000 is built with a FEM-optimized construction and linear roller motion guides. This combination ensures machine rigidity and minimizes thermal distortion, resulting in exceptional machining precision.
- Efficiency and Automation: The NHP 8000 features a servo-driven rotary pallet changer for fast and automatic workpiece exchange. Additionally, it offers an automatic tool changer (ATC) with a tool change time of under a second, minimizing non-cutting time and maximizing productivity.
- Scalability: The NHP 8000 can be customized to meet specific production needs. A wide variety of factory-installed options are available, including multi-pallet changers, large capacity tool magazines, and hydraulic fixture units.
