Selection of the Steidle-device
1.1. Which
is the correct device for my machine?
Our overview “Characteristics and appropriateness”
offers a first help for selection (see page 4 of our
complete catalogue or
here). One of our friendly employees would
be pleased to help you with a more detailed advice.

1.2. How do I find the appropriate MQL system?
Steidle GmbH offers you
several systems. Which one is optimum for your use
depends on the technical conditions on the one hand (machines,
techniques, material, processes etc.) and on the other
hand, on your objectives, your budget and other
requirements on the system. These questions are
discussed in a meeting with us and our sales partners so
that an appropriate device of our product range can be
offered to you.

1.3. Can
I speak with a user beforehand, who has a similar
application?
If we know customer using a similar application and
this customer gives his agreement we can establish such
a contact. Otherwise, the multitude of application
examples in the
complete catalogue / on the
homepage can
be useful to you.

The configuration of a Steidle-device
2.1.
Base addition
2.1.1.
How
many nozzles do I need?
Normally, 1 nozzle per cutting tool to be lubricated is
sufficient. At least 2 nozzles are to be recommended for
milling in view of the multi-dimensional traversing
directions. For smaller saws (band height up to 34 mm,
blade diameter up to 300-350 mm), one nozzle block with
one feed pipe is sufficient; larger saws require several.
back
to the
top
2.1.2.
Can I connect two or more nozzles to one feed
tube?
No. Since this could never guarantee a uniform
distribution, a nozzle could be undersupplied. In view
of the already low minimum quantities a failure of the
lubrication system could result.
back
to the
top
2.1.3.
Can I increase the number of nozzles later?
This is not possible for most of the devices without a
larger modification. Therefore the number of the nozzles
required should be selected right from the beginning.

top
2.2.
Reservoir
2.2.1.
How large should the reservoir be
selected?
Normally 20-50 ml is sprayed per nozzle and spraying
hour with the MQL. If this value is multiplied with the
effective spraying time per day, you receive the medium
consumption of the system per day. Select the size of
the reservoir so that you do not have to refill too many
times.
Consumption
(ml / day) = 20 – 50 ml x number of nozzles x spraying
time / day
back
to the
top
2.2.2.
When do I need a float switch?
A float switch is reasonable, if the system with the
reservoir is not located in the field of view of the
user or if a heavy contamination of the reservoir or the
filling level display has to be expected due to the
working environment; in addition, if a serious damage
would quickly occur due to a failure of the lubrication
system.
back
to the
top
2.2.3.
Shall I take the float switch as NC (=opener) or NO (=closer)?
In most cases, both can be used for the control which
monitors the contact signal of the float switch. However,
the NC offers the advantage that a possible parting of a
cable in the line is monitored at the same time.

2.3. Drive
2.3.1.
Do I need current to operate the systems?
No. All Steidle systems work exclusively with
compressed air. Current is only necessary to open the
compressed air supply, if you have selected an electric
drive control.
back
to the
top
2.3.2.
How much compressed air do I need for the system?
The devices which spray the medium from outside by
spray air (for e.g.
Lubrimat/
Sawfix/
/Spraymat
) need approx 50 NI/min per
nozzle at 6 bar under normal conditions with the
external lubrication. With the internal lubrication (Toolmat /
Centermat), the consumption amounts to approx. 20
– 150 NL/min per tool based on the size of the cooling
duct. The “airless systems”
Pulsomat
do not have any
relevant compressed air use.
back
to the
top
2.3.3.
Can I also use the compressed air of my machine (instead
of the compressed air from the network)?
Yes, but in most cases only as control air. If it is
used as working air, the air pressure and the compressed
air flow rate must be adapted to the system requirements.

top
2.4.
Feed tube
2.4.1.
Which length do I need?
Please consider where you wish to install the basic
device and the nozzles and how you wish to lay the feed
tubes between them. Measure this distance generously.
Please note the maximum tube lengths depending on the
system (see technical data).
back
to the
top
2.4.2.
What is
the
length maximum?
The devices with piston pump technology (for e.g.
Lubrimat/
Sawfix /
Toolmat /
Centermat)
have the standard length
of 3 meter. Longer feed tubes up to 20 m are available.
For the low-pressure system
Spraymatthe feed tube
length is limited (see
Technical
Data).
back
to the
top
2.4.3.
Can I shorten or lengthen a tube on my own?
This is possible only in the system
Centermat.
back
to the
top
2.4.4.
Can I install the tubes in a cable drag chain?
Yes, in this case, please select always the PUN
synthetic tube version (presently on demand), since the
danger of rubbing against other cables is too large for
the tubes with metal sleeve.
back
to the
top
2.5.
Nozzles
2.5.1.
Which nozzle length do I need?
By default, nozzles are 300mmm long. Other lengths are
possible on demand.
Please note that for larger lengths a decrease of the
position stability has to be expected.
back
to the
top
2.5.2.
Can I shorten a nozzle myself?
No. The nozzles have a coaxial design and therefore,
cannot be shortened.
