5.3 Fire extinguishing system for cooling lubricant
fires
After consultation with the customer, INDEX-Werke GmbH & Co. KG will equip
machines with a fire extinguishing system to extinguish cooling lubricant fires if this
is required for the machine's expected use.
5.3.1 Intended use of the fire extinguishing system
The fire extinguishing system is intended only for detecting and extinguishing cool-
ing lubricant fires within the machine's work area.
The fire extinguishing system is enabled only when the work area door is closed.
If a fire extinguishing system is used, the ambient conditions for trans-
port and storage of the machine are reduced to -10 °C to +50 °C.
The fire extinguishing system allows the use of a water-based cooling lubricant with
an oil content greater than 15% and cutting oil based on mineral oil.
The amount of cooling lubricant at the cutting edge must always be high enough to
prevent the development of ignitable mists.
The cooling lubricant must have the following properties:
• Viscosity ≥ 10
• Flash point > 145°C
• Evaporation loss < 60%
Servicing should be carried out at regular intervals by qualified personnel according
to the specifications of the manufacturer of the fire extinguishing system.
Push in the extinguishing opening (if there is one) only in case of fire. During opera-
tion, the opening must be closed.
After the extinguishing process, the cover must be refitted.
5.3.2 Foreseeable misuse of the fire extinguishing system
The fire extinguishing system is designed to combat fires of combustible materials
or their dust.
When combustible materials are used, other suitable measures must be taken to
protect against fires and explosions.
