NOTE
• For a model for which no data is indicated for "Rotor inner surface not machined," machine the inner surface of the
rotor and spindle so that the specified range of the "interference for shrinking" is reserved. Determine the diameter
of the spindle within the range indicated as dimension J in the table.
• For a model for which data is indicated for "Rotor inner surface not machined," no inner surface machining is
recommended. Finish the spindle within the dimension J range. When machining the inner surface of the rotor,
follow the above note.
• When cutting fluid is used for machining, remove moisture completely from the core after machining.
• Machine on the parts designated by FANUC. Incorrect machining will affect the motor life. Read "II.INSTRUCTION"
before machining.
