Overview

The DMG Mori GEAR production by NMV 5000 DCG is a purpose-built variant of the NMV 5000 DCG vertical 5-axis machining center, specifically configured for precision gear cutting using simultaneous 5-axis interpolation. This machine eliminates the need for dedicated hobbing, shaping, or grinding machines by using standard milling tools to cut gear teeth through programmed 5-axis toolpaths, combined with integrated grinding capability for finish operations.

With 730 x 760 x 850 mm (28.7 x 29.9 x 33.5 in) of axis travel, the GEAR production variant features a different envelope than the standard NMV 5000 DCG (730 x 510 x 510 mm), with significantly more Y and Z travel to accommodate the kinematics required for gear cutting toolpaths. The machine handles workpieces up to 800 mm (31.5 in) in diameter and 1,000 mm (39.4 in) tall, with a 500 kg (1,102 lb) table load.

The DCG (Driven at the Center of Gravity) drive technology positions the ball screw at the center of gravity of each moving component, eliminating pitching moment vibration that would compromise gear tooth accuracy. This inherent stability is critical when cutting gear profiles where surface finish and geometric accuracy directly determine gear noise, efficiency, and service life.

The GEAR production+ package includes DMG Mori technology cycles optimized for gear cutting: spur gears, helical gears, bevel gears, worm gears, and internal ring gears can all be produced on a single machine. Integrated grinding capability enables finish operations to achieve the surface quality and geometric accuracy required by DIN/ISO gear standards.

Control is MAPPS Fanuc with CELOS X compatibility. For manufacturers who produce diverse gear types in small to medium batches, or who need prototype gear capability without investing in dedicated gear cutting equipment, the GEAR production by NMV 5000 DCG provides a uniquely flexible solution.

Strengths & Limitations

Strengths

Produces spur, helical, bevel, worm, and internal ring gears on a single 5-axis platform without dedicated hobbing equipment
DCG drive technology provides the vibration-free cutting essential for accurate gear tooth profiles and low-noise gears
Integrated grinding capability enables finish operations to DIN/ISO gear standards without a separate grinder
730 x 760 x 850 mm travel with 800 mm workpiece diameter handles a wide range of industrial gear sizes
Eliminates capital investment in dedicated hobbing, shaping, and gear grinding machines for small-to-medium batch production
500 kg table load accommodates heavier steel gear blanks and fixtures common in gear manufacturing

Limitations

5-axis gear cutting cycle times are longer than dedicated hobbing machines for high-volume production
BT40 taper limits tooling rigidity for the heaviest gear roughing operations in hardened steel
Requires specialized 5-axis gear cutting programming knowledge beyond standard machining center operation
Higher cost than the standard NMV 5000 DCG due to gear-specific technology cycles and grinding integration

Best For

Gear manufacturers producing diverse gear types in small to medium batches who need flexibility over dedicated equipment Aerospace gear shops machining precision spur and bevel gears from hardened steel and titanium alloys Prototype and R&D facilities needing to produce sample gears quickly without dedicated gear cutting machinery Automotive suppliers producing low-volume specialty gears, timing gears, and drivetrain components Job shops wanting to add gear cutting capability without investing in separate hobbing and grinding machines

Frequently Asked Questions

01 How does gear cutting on the NMV 5000 DCG compare to a dedicated hobbing machine?

A dedicated CNC hobbing machine is 3-5x faster for high-volume production of standard gear profiles. The GEAR production NMV 5000 DCG excels in flexibility: it can cut any gear type (spur, helical, bevel, worm) on one machine using standard milling tools, and it doubles as a full 5-axis machining center for non-gear work. For batch sizes under 500 pieces or shops producing diverse gear types, it is often more economical than dedicated equipment.

02 What gear quality levels can this machine achieve?

With the integrated grinding capability, the GEAR production NMV 5000 DCG can achieve gear quality levels meeting DIN 6-7 and equivalent ISO standards. The DCG drive technology minimizes vibration-induced errors in the tooth profile. For DIN 4-5 quality requirements, dedicated gear grinding remains necessary.

03 How does this differ from the standard NMV 5000 DCG?

The GEAR production variant features significantly more Y-travel (760 vs 510 mm) and Z-travel (850 vs 510 mm), larger workpiece capacity (800 mm diameter, 1,000 mm height vs 500/450 mm), and includes gear-specific technology cycles and integrated grinding. The standard NMV 5000 DCG is a general-purpose 5-axis platform; the GEAR variant is factory-configured for gear cutting applications.

04 Can I use this machine for non-gear work?

Yes. The GEAR production NMV 5000 DCG retains full 5-axis simultaneous machining capability. When not cutting gears, it functions as a standard NMV 5000 DCG with enhanced Y/Z travel. This dual-use capability is a key advantage for shops that do not have enough gear work to justify a dedicated machine.
