External and internal grinding heads

The LGG machines are perfect for generating grinding and profile grinding. As standard, the machines are equipped with an external grinding head and can be supplemented with an internal grinding head.

In both external grinding heads, the balancing systems are integrated in the spindle. High drive power and speeds offer big advantages for example, when using new grinding material. Simple and fast replacement of the grinding arbor is made possible by the use of modern tool holding. For collision-critical workpieces and for special tooth corrections, small grinding tool diameters are available.

Fast and easy changeover

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