INDEX B400

The INDEX B400 represents a logical further development of proven manufacturing solutions within the INDEX Group. Individually equipped, this new flexible universal lathe takes its place both in tooling and prototyping, but also in production Decades of accumulated know-how is reflected in numerous design details, such as in a pocket in the panel above the mainspindle which ensures collision-free use of long boring bars.
