The Doosan NHP 5500 2nd Generation is a horizontal machining center (HMC) designed for high-precision and productive metal removal. Building on the success of the previous generation, this machine boasts several improvements for enhanced accuracy, faster cycle times, and overall machining efficiency.
Features:
- Improved Productivity: The NHP 5500 2nd Generation features faster acceleration/deceleration rates for the X, Y, and Z axes, along with a quicker tool change time and reduced table rotation time. This translates to significant reductions in non-cutting times, leading to increased overall throughput.
- Enhanced Machining Accuracy: Thermal stability is crucial for maintaining precision machining. The NHP 5500 2nd Generation comes equipped with a spindle smart thermal control system, X, Y, and Z-axis ball screw shaft and nut cooling, and a standard 3-point support structure. These features minimize thermal distortion and ensure consistent accuracy throughout long machining operations.
