9 MAINTENANCE
Read this section carefully before attempting any maintenance on the electro-spindle. This section contains information
that is important for the safety of maintenance personnel and for the reliability of maintenance work itself.
All applicable safety precautions must be taken whenever maintenance work is done on the electro-spindle. In particular:
• Maintenance and/or lubrication must be performed only by qualified, expert personnel, with the authorisation of
factory management, in compliance with applicable safety directives and standards, and with the use of suitable
tools and instruments.
• When performing maintenance, always wear suitable clothing such as tight fitting work overalls and safety shoes.
Never wear long or slack clothing or clothes with parts that hang loose.
• When performing maintenance on a machine, cordon it off and mark it clearly with panels stating “MACHINE
UNDERGOING MAINTENANCE”.
During all maintenance work make sure that the electro-spindle is:
• disconnected and insulated from the electrical power supply;
• fully stopped (not still spinning).
Maintenance managers must ensure that their team is trained to ensure optimum co-ordination and safety. All persons
performing maintenance must remain fully visible to colleagues at all times so that they can signal for assistance if
necessary.
USE ONLY SUITABLE LIFTING AND MOVING EQUIPMENT TO DISCONNECT OR REMOVE HEAVY PARTS FROM THE MACHINE.
i
SPECIAL TOOLS ARE NOT NORMALLY REQUIRED FOR ELECTRO-SPINDLE MAINTENANCE.
9.1 SCHEDULED MAINTENANCE - CLEANING THE SPINDLE SHAFT TOOL HOUSING
Always keep the tool housing in the spindle shaft perfectly clean and free from dust, grease, coolant, oil, metal shavings,
and corrosion or lime scale.
Dirty housings cause incorrect tool seating, misalignment with respect to the spindle’s axis of rotation, and tool slippage
(on models without a key). Dirt can also damage the surface of the housing, causing poor machining precision, and
causing risk of injury to operating personnel.
For this reason, check regularly (at least once a day if tools are changed frequently) that the surfaces of the spindle
shaft, tool housing and tool itself are perfectly clean.
These parts can be cleaned using standard commercial detergents for metal surfaces. When cleaning, take the
opportunity to check the condition of the surfaces for wear or damage.
9.2 OCCASIONAL MAINTENANCE
• Clean the grill of the cooling fan and remove any objects blocking the airways.
• Check that the fixing bolts securing the electro-spindle to the machine are tight.
THE BEARINGS ARE LUBRICATED FOR LIFE AND DO NOT REQUIRE GREASING.
9.3 REMOVING AND REFITTING COMPONENT PARTS
COMPONENT PARTS MUST BE REMOVED AND REFITTED ONLY BY QUALIFIED PERSONNEL AUTHORISED BY HSD S.P.A..
ONLY THE REPLACEMENT OF PARTS WITH ORIGINAL HSD SPARES AND THE SUBSEQUENT ADJUSTMENT OF THE
NEWLY FITTED PARTS IS AUTHORISED. NO OTHER TYPE OF WORK IS AUTHORISED AND, IF DONE, WILL LEAD TO THE
CANCELLATION OF THE WARRANTY.
PLEASE CONTACT HSD CUSTOMER CARE SERVICE IF YOU NEED MORE INFORMATION.
