This User’s Manual covers the functions of the ND 780 for
both milling and turning applications. Operational
information is arranged in three sections: General
Operations, Mill Specific Operations and Turn Specific
Operations.
General Information
e.g. on the behavior of the ND 780.
Warning – Refer to accompanying documents
e.g. when a special tool is required for a function.
Caution - Risk of electric shock
e.g. when opening a housing.
The ND 780 and the machine tool must be prepared by the
machine tool builder to perform this function.
