External and internal grinding heads

Process-optimized external grinding heads and internal grinding arms are available for the LGG. Balancing systems inside the spindle are used in both external grinding heads (GH 320 and GH 240 CB). On the GH 320 CB, the balancing system is integrated in the arbor.

High drive power and speeds are major advantages – for example, when using new grinding materials. The modern tool holding makes it possible to replace the grinding arbor quickly and easily.

Small grinding tool diameters are available for collision-critical workpieces and for special tooth corrections.

With the GH 320 CB grinding head, it is now also possible to efficiently grind optimal-quality workpieces up to module 14 mm.

Fast and easy changeover

The adaptable internal grinding arms can be mounted quickly and easily on the external grinding head and are driven using the main drive. Other grinding heads can be provided on request.
