Second-Generation HMCs Optimized for Shorter Tools

DMG MORI’s NHX 4000 2nd Generation and NHX 5000 2nd Generation horizontal machining centers are said to be suitable for single-part manufacturing ranging to serial production.

DMG MORI’s NHX 4000 2nd Generation and NHX 5000 2nd Generation horizontal machining centers are said to be suitable for single-part manufacturing ranging to serial production. The 2nd Generation models are based on the NHX 4000 HMC. High-torque and high-speed versions are also available, and the HMCs can be equipped with automation options such as round, carrier and linear pallet magazines.  

The NHX 4000 2nd Generation accommodates workpieces ranging to 630 mm (24.8") in diameter and 900 mm (35.4") in height. Its work area measures 560 × 560 × 660 mm (22.0" × 22.0" × 26.0"). The NHX 5000 2nd Generation accommodates workpieces as wide as 800 mm (31.5") and as tall as 1,000 mm (39.4") in its 730 × 730 × 880 mm (28.7" × 28.7" × 34.6") work area.

The linear axes travel at speeds of 60 m/min. (2,362.2 ipm) in the standard version and 96 m/min. (3,779.5 ipm) optionally, with acceleration ranging to 1.2 g. According to the company, chip-to-chip times are 2.2 sec., and the Direct Drive Table (DDM technology) offers speeds ranging to 100 rpm, ensuring the shortest possible positioning times.

The standard configuration offers a 15,000-rpm spindle with torque of 111 Nm (81.9 foot-pounds), while the high-torque version provides 200 Nm (147.5 foot-pounds) at the same rpm. The high-speed version offers as much as 20,000 rpm. The design has been optimized for shorter tools, with distance from the spindle nose to the pallet center minimized to 70 mm (2.8") for longer tool life and higher process stability.

The HMCs are equipped with DMG MORI’s Celos with MAPPS V on a Mitsubishi control. Celos is compatible with MRP and ERP systems and can be networked with CAD/CAM applications. Celos apps enable consistent management, documentation and visualization of job, process and machine data.
