B400 in focus


Structured machine design


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.

Ergonomic operating concept

The generously dimensioned work area ensures best accessibility for setup of the INDEX B400. Main spindle and tool turret can be accessed easily allowing fast and flexible setup and changeover. The sophisticated work area concept with steep-sloping and smooth covers provides for the ideal chip flow and prevents chip nests.

 

Highlights

  • Fast setup

  • Excellent access to thework area

  • Good chip flow

 

 


The W-serration

The patented INDEX W-serration for high change and repeat accuracy of the tool.

  • Short tooling/setting-uptimes

  • High change accuracy bylong fixing grooves

  • Extended life of cutting inserts

  • DIN 69880-compatible

  • Suitable for stationary and live tools

 

 


Ideal for a wide range of parts

With the universal turning machine B400, it is possible to machine a wide variety of workpieces from bars up to dia. 82 mm and in the chuck up to dia. 315 mm.
