Index’s G420 turn-mill features two identical 3,500-rpm spindles with 315-mm (400-mm optional) chucks as well as a five-axis milling spindle. The machine’s stability and dynamic response make it a good choice for working with difficult-to-machine materials such as those used in aerospace, and machining large, complex parts in a single setup, the company says.

The main and counter spindles each accommodate barstock ranging to 102 mm in diameter and can chuck parts ranging to 315 mm in diameter (400 mm optional). The large work area provides space for parts as long as 1,600 mm and incorporates an ergonomic design to optimize operator accessibility. An optional workpiece handling system can be incorporated for loading, unloading and transferring parts weighing up to 20 kg and measuring 120 mm in diameter.

The milling spindle offers 26 kW of power, 150 Nm of torque and 12,000 rpm with an HSK-T63 interface. A Capto C6 option provides 27.5 kW, 100 Nm and 18,000 rpm. Optimized Y/B quill kinematics enable highly productive simultaneous five-axis milling operations to tackle complex geometries, the company says.

Designed as a modular system, the G420 can accommodate up to three tool carrier, each equipped with a Y axis. Turret steady rests are available to ensure maximum stability when machining long parts or shafts.

Ergonomics and flexibility were major considerations when designing the G420, Index says. The goal was to make all relevant components easily accessible to operating and maintenance personnel. A chip conveyor can be mounted to either side of the machine to make optimum use of available floorspace. Automation such as conveyor belts and robot handling units can be integrated to provide additional enhancements to productivity.
