G400 / G420 in Focus
Wide range of parts
For applications in the automotive, aerospace or mechanical engineering sectors
The INDEX G420 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.
Integrated automation solutions for efficient production
The integrated workpiece handling unit is available as an option. It can be used for loading and unloading as well as for the removal of remnants and is suitable for parts weighing up to 25 kg and with a diameter of up to D 120 mm. The handling unit is equipped with 2 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 INDEX G420 modular system offers a wide range of options. Up to 3 tool carriers can be integrated into the working area – all equipped with a Y axis. The working area offers ample space for machining any kind of workpieces. The working area can accommodate parts up to a length of 1600 mm. The powerful main and counter spindles are designed for bar diameters up to D 120 mm and for chuck parts up to D 315 mm (optionally D 400 mm). Turret steady rests are available for machining long or shafttype parts.
Of course, the INDEX G420 is also capable of simultaneous 5-axis machining.
The ergonomic setup and operating concept was of great importance for the new design. All relevant components are easily accessible for operating and maintenance personnel. Optionally, an integrated 2-axis workpiece handling system matched to the machining processes can be used for loading and unloading the machine.
