The NMV5000 DCG is the new 5-axis machining centre from Mori Seiki. With its Box-in-Box construction and twin ball screws on the Y and Z-axes, the NMV5000 DCG moves through its centre of gravity, avoiding out of balance forces, and maximizes its rigidity with zero table overhang.

Access to the machine is easy for the operator as the rotary table moves sideways making it easy to examine a part irrespective of its angle. A retractable roof panel allows the operator to reach right into the machine and provides sufficient room to move heavy components by crane. Where pallet loading is fitted, this is to the side of the machine, so that it does not impede operator access and also gives space for complex part handling arrangements.

As well as DCG® (Driven at the Centre of Gravity), the machine also features ORCTM (Octagonal Ram Construction) and DDMTM (Direct Drive Motor). ORCTM combines rigidity for the Z-axis with thermal stability due to its symmetrical design. Direct drive motors are fitted to the two rotary axes and the spindle, eliminating the vibration and backlash associated with gears, belts and worm drives. Spindle speeds can be up to 20,000rpm, while the C-axis can rotate at 1,200rpm for high precision turning operations. Metal removal rates in carbon steel can reach 336mL/min, which is 65% greater than the previous model.

MAPPS III, Mori Seiki’s latest interactive control system, simplifies 5-axis programming and simulates the machine’s kinematics, avoiding collisions with the tool, part or machine structure when moving several axes at the same time.
