Hollow spindles

Very rigid hollow milling spindle in flat square design for the use of hollow cutters.

Special designed to be retrofitted to any milling machines by using adapter plates.

The big bearing clearance combined with a huge bearing package at the front gives the necessary stiffness for using long hollow cutters.

Additional advantage will be lower strain on the bearing which results in much longer lifetime.

Because of the special electrical design of the spindle there is already a high torque with low rpm. So there is always enough power at any time.

For the operation of the spindle a converter is necessary.
