Directive 99/92/EC.
The electrospindle:
- must be powered with sinusoidal electricity supplied by a static frequency converter or
inverter;
- it must be used only with tool holders and tools balanced in group in grade G2.5 at the maximum
operating speed or higher, according to the standard ISO 1940/1;
- it must be fitted exclusively with tool holders:
- HSK models: HSK tool holders with dimensions and tolerance according to DIN 69893;
- ISO models: ISO tool holders with dimensions and tolerance according to DIN 69871-1;
- meet all the specifications set out in chap. 2 paragraph 2.7;
The operator must select the rotation speed of the electrospindle so that it is LOWER :
- than the maximum rotation speed permitted for the tool;
- than the maximum rotation speed permitted for the tool holder;
- than the maximum speed of the electrospindle;
- than the maximum rotation speed permitted for the electrospindle set out in the table in chap. 2 paragraph 2.8.2
based on the material and size of the tool used.
The machine:
- must have an interlock between the electrospindle start function and the safety of the tool change
performed;
- must have an interlock between the tool change function and the actual braking of the rotating unit;
- must cut off the electrospindle power supply in case of alarm or emergency; the power supply
must be restored manually.
The manufacturer will in no way be responsible for faults caused to the electrospindle or the machine that it
is installed in, due to incorrect application or design choices.
1.3 Risks connected to using the product
HITECO does not know and cannot know the product installation methods, therefore the installer or the final
customer must carry out a risk assessment specifically for the installation method and type.
In any case the installer must guarantee that there is an adequate degree of protection against the risk of accidental
contacts with moving parts.
The installer and the user must also bear in mind other types of risk, in particular, those due to the entrance of
foreign bodies and conveying explosive, flammable or toxic gases at high temperature.
Moreover the risk inherent the maintenance operations must be considered, as the operations mus be carried out in
maximum safety conditions, with the product cut off and the certainty that the tool is stopped.
At the end of the choices made and based on the product installation method defined and applied by the installer
and/or customer, the definitive machine can be considered a finished machine, according to the machinery
directive. An overall risk assessment must be carried out a declaration of conformity must be drawn up, according
to attachment IIA of directive 2006/42/EC.

In fact dirt and dents can compromise the perfect coupling between the tool holder and the electrospindle spindle.
Clean the tool holder as indicated in chap. 7 paragraph 7.1. If there are any dents replace the tool holder.
- Always use perfectly sharp tools.
- Tighten the tool correctly in the tool holder.
- Do not damaged and/or imbalanced tools. The specifications on the balancing grade of the tool unit (tool holder
taper+tool+fixing parts) are indicated in chap. 2 paragraph 2.8.
When using ting nuts and elastic collets to fix the tool in the tool holder, check that all the coupling surfaces are
clean and without dents.
- The operator must select the rotation speed of the electrospindle so that it is LOWER :
- than the maximum rotation speed permitted for the tool;
- than the maximum rotation speed permitted for the tool holder;
- than the maximum speed of the electrospindle;
- than the maximum rotation speed permitted for the electrospindle set out in the table in chap. 2 paragraph 2.8.2
based on the material and size of the tool used.
- Before starting and using the electrospindle check that the rotation speed is the one selected
previously.
- Never rotate the electrospindles with ISO or HSK tool taper without the tool inserted!
The feed speed of the machine axes on which the electrospindle is installed must be selected so that:
- it is suitable for the power available to the electrospindle;
- it is suitable for the requested degree of finish;
- doe not trigger dangerous vibrations on the machine and/or piece being machined.
- The compressed air circuit that feeds the electrospindle must be the one specified in chap. 4 paragraph 4.4.3.
Make sure that the solenoid valves have single outlets and not shared with other solenoid valves. The outlet fitted
on the solenoid valves must be able to guarantee a fast compressed air outlet and it be must be sized to ensure
that it is not blocked due to dirt buildup.
- Check that the pipes of the compressed air circuit are nit crushed.
- Do not place the electrospindle in areas classified as potentially explosive atmospheres as defined by directive
99/92/EC.
- It is absolutely forbidden to neutralise, remove, change or render inefficient
any safety, protection or control device of the individual parts and of the entire product.
- Do not insert hands, arms or any part of the body close to the moving parts.
- The product must not be used in potentially explosive atmospheres.
- Unauthorised operators must not eliminate any defects or faults in the operation of the product and/or
alter the type of operation and installation.
- At at end of any unscheduled intervention that required the removal of guards, barriers or other
protection, restore their operation before restarting the product, making sure that they are positioned correctly and
that they are effective.
- All the protection and safety devices must be maintained in perfect and efficient conditions. The
recommendation and danger warning plates must be kept fully operational and must not be removed.
- When troubleshooting any faults on the product adopt all the precautions described in the Instruction Manual,
designed to prevent injuries to people or damaging property.
