Efficient complete machining with Index G220

The new generation of the Index G220 turn-mill centre has arrived. With 76 mm spindle clearance, 230 mm chuck diameter and a turning length of 900 mm, this model rounds off the completely redesigned G series by adding a product of smaller dimensions.

Based on a rigid, vibration-damping machine bed in a mineral cast block design and using generously dimensioned linear guides in the X and Z axes, the new G220 offers stability, damping properties and dynamic attributes. A key element is the Z-axis slide with motorised milling spindle and hydro-dynamically mounted Y/B axis arranged above the axis of rotation.

The spindle drive (40 kW, 207 Nm, 6000 rpm) facilitates a range of drilling and milling operations, including five-axis machining. During machining, the milling spindle operates with a tool magazine offering space for up to 139 tools (HSK-T63 or HSK-T40). According to Index, the machine stands out because of its particularly simple set up. Next to the usual set-up station located at the front, further access to the two tool chains is available at the rear of the magazine. From here, the operator can re-tool one chain while the other is in use.

Notably, the two tool turrets arranged at the bottom are also responsible for efficient machining performance. These turrets are not only able to move in the X and Z directions, but also in the Y direction.

Thanks to the large working area and distance between the main and counter spindles, simultaneous machining is possible with the motorised milling spindle and tool turrets at the main and counter spindles, with no risk of collision. The Index G220 is available in the UK from Kingsbury Machine Tools.
