The INDEX G520 turn-mill center offers the best performance for customers from the mechanical engineering, automotive and aerospace industries, with high availability and process reliability – the complete solution when it comes to high-performance machining of large workpieces.


Complete machining based on a modular system

The modular system in this series offers a wide range of options. Up to 3 tool carriers can be integrated into the work area. The work area offers ample space to machine any kind of workpiece. The working range allows for parts up to 1,600/2,300 mm in length. The powerful main and counter spindles are designed for bar diameters up to 120 mm and for chucked part diameters of up to 500 mm. Turret steady rests are available for machining long or shaftshaped parts.

The INDEX G520 features a powerful motorized milling spindle capable of performing simultaneous 5-axis machining. The ergonomic setup and operating concept played a major role in the new design. All the relevant components are easily accessible for operating and maintenance personnel. The modular robot cell iXcenter is available for all machines in this series, for flexible feeding and discharging of blanks and finished parts.
