HSD
§ 9 INSTALLAZIONE
HSD S.p.a. does not and cannot know the methods adopted by the user to install
the spindles. It is therefore the responsibility of the installer or end user to carry
out a risk analysis for each specific installation type and the methods adopted.
It is furthermore the responsibility of the installer to ensure that there is sufficient
protection against accidental contact with moving parts.
The installer and user must also take all the necessary precautions to prevent
other types of risk, particularly those deriving from foreign bodies entering the
equipment, contact with explosive, flammable, toxic or high temperature gases.
Risks relating to maintenance operations must also be taken into consideration.
Maintenance must be performed in conditions of maximum safety, with
electrospindle power switched off and with no risk of tool movement.
9.1 UTILITY SUPPLIES IN THE FACTORY
All preparation work for installation of the electrospindle is the responsibility of the Customer (e.g.
the provision of electricity and compressed air lines, etc.).
The electrical power line to the electrospindle must have sufficient capacity. Connection to the
supply network must be performed by qualified electricians. The Customer is responsible for the
entire electrical supply as far as the electrospindle connectors.
The Customer's attention is drawn to the need to ensure that all safety aspects relating to the
grounding of the electrospindle are complied with.
The ground system must furthermore comply with the standards applicable in the country or state
of installation and must be checked regularly by qualified electricians.
9.2 FIXING
(See figures of chapter § 8)
To fix the electrospindle directly onto the machinery use n°8 M8 stainless steel screws.
To fix an electrospindle equipped with the fixing support use n°8 M10 stainless steel screws and
n°2 reference pins.
9.3 HYDRAULIC CONNECTIONS
See the figures in chapter § 8 for the location and sizes of connections.
See the following sections of this chapter for fluid specifications.
9.4 MOTOR COOLING
The Customer must provide an adequate cooling circuit, with a housing around the spindle for
coolant circulation.
The designer of the machine on which the electrospindle is installed is also responsible for the
design and implementation of the cooling system. The following table indicates the minimum
values that must be respected:
Minimum flow 5 liters / minute
Cooler set temperature 25±3°C
Max. coolant temperature 40°C
Min. inside diameter of delivery and return lines 10 mm
Use water with 10% ethylene glycol and anti-corrosion additives.
