Index B400
The universal lathe INDEX B400 impresses with its innovative machine layout and raises universal turning to a new dimension. The stiff and vibration-damping machine bed in mineral cast monoblock design ensures best results when machining complex workpieces from batch size 1. With a high spindle torque up to high spindle speeds, even difficult-to-cut materials can be machined powerfully and reliably. Special feature of the INDEX B400 is the completely newly designed and clearly structured work area for a variety of applications. With the optionally available counter spindle, rear-end machining can be carried out with high precision. The ergonomic design ensures quick setup and easy control of the machine. The proven INDEX iXpanel operating concept and the 18.5“ touch monitor provide the operator at any time with all relevant data for economical production and access to networked production.
