The INDEX G320 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 medium-sized workpieces.


Integrated automation solutions for efficient production

The integrated workpiece handling unit is available as an option. It can be used equally for loading and unloading as well as for the removal of remnants and is designed for parts weighing up to 20 kg and with a diameter of up to 120 mm (shaft) or 200 mm (flange). The handling unit is equipped with 2 or 3 CNC axes that are operated from the machine control. Further individual automation solutions, such as conveyor belts or robot handling with ancillary functions can be integrated on a customer-specific basis.


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, and all of them can be equipped with a Y axis. The work area offers ample space to machine any kind of workpiece, accommodating medium-sized parts up to 1,400 mm in length.
The powerful main and counter spindles are designed for bar diameters up to 102 mm and for chuck part diameters of up to 315 mm. Turret steady rests are available for machining long or shafttype parts.

The INDEX G320 features a powerful motor milling spindle capable of 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. Optionally, an integrated workpiece handling system matched to the machining processes can be used for loading and unloading shaft and flange parts. Furthermore, the modular robot cell iXcenter is available for all machines in this series, for flexible feeding and discharging of
blanks and finished parts.
