11 TROUBLE SHOOTING
PROBLEM
Excessive vibration during
machining
PROBABLE CAUSE
• Unbalanced tool
• Incorrectly fitted tool
• Excessive cutting parameters
• Incorrect inverter settings
• Tools too big or too heavy
Bearing noise
•
•
The electro-spindle get very hot and •
is stopped by the PTC thermistor •
signal
•
•
Damaged bearings
Incorrect inverter settings
Power settings too high
Machining speeds too low for the
power requirement
Cooling fan grill blocked
Cooling fan broken
CORRECTIVE ACTION
• Balance the tool. See section (see data
sheet).
• Check that the tool is correctly fitted
and that the mating surfaces are clean.
• Adjust (reduce or increase) the various
cutting parameters.
• Check the inverter settings.
• Try machining with smaller tools.
• Replace the electro-spindle.
• Set the inverter parameters according
to the plated values (see data sheet).
• Contact the HSD Technical Office.
• Check the cooling fan grill and remove
any blockage.
• Replace the broken fan.
12 DISPOSING OF THE ELECTRO-SPINDLE
AT THE END OF THE ELECTRO-SPINDLE’S WORKING LIFE IT IS THE CUSTOMER’S RESPONSIBILITY TO DISPOSE OF IT CORRECTLY.
FIRST OF ALL, CLEAN THE UNIT AND SEPARATE THE VARIOUS COMPONENTS INTO MECHANICAL AND ELECTRICAL PARTS. THEN
SEPARATE THE COMPONENT PARTS ACCORDING TO TYPE OF MATERIAL: ELECTRIC MOTORS (COPPER WINDINGS), METAL PARTS
(BODY, ETC.), PLASTIC PARTS, ETC.. DISPOSE OF THE VARIOUS MATERIALS IN COMPLIANCE WITH THE LAWS AND REGULATIONS
APPLICABLE IN THE COUNTRY WHERE THE ELECTRO-SPINDLE HAS BEEN INSTALLED.
