Index G300/320

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.
