4.1 Functional Description
The Multi-Marker with its pneumatic needle marking is used for en-
graving metal and hard plastic parts, e.g. for the automatic part identi-
fication.
During the marking process, the needle on the marking head displac-
es and compacts the material of the workpiece which forms the typi-
cal marking.

Multi-Marker
By regulating the valve control of the compressed air unit (max. 6 bar)
the impact force and the marking speed of the marking head can be
adjusted.
The needle in the marking head is spring loaded. During the marking
process, the needle frequency determines the marking result. The
standard frequency is 80 Hz / s.
The marking frequency is determined by the amount of opening and
closing impulses of the magnet valve.
The head with the marking needle is moved by an electric motor
(24V). The motor is software controlled. The movement depends on
the programmed marking picture.
The delivered software „SchillMarker II“ controls the marking ma-
chine. A PC must therefore be connected by the corresponding inter-
face. After the transfer of the marking parameters, the data chip that
is already integrated into the Multi-Marker allows a PC-independent
marking.
4.1.1 Introduction to Marking Technology
The marking procedure displaces material, and does not remove it.
This means the material is compacted at the point where the needle
penetrates the material surface. At the same time the material is dis-
placed, producing a warp of material at the side and in front of the
needle puncture point.
The deeper the needle penetrates the material, the higher the materi-
al warp.
Penetration depth:
The penetration depth is defined by the needle weight, the spacing of
the needle to the workpiece and the pressure applied to the needle,
together with the geometry of the needle tip.
Regardless of the needle type and geometry, as a basic rule it always
applies that:
The larger the spacing of the needle to the workpiece, the higher the
pressure setting at the maintenance unit, the deeper the marking.
The penetration depth defines the marking quality!
Fine lettering – slight depth
Keep the needle spacing to the workpiece as small as possible (ap-
prox. 0.5 mm). Reduce the pressure at the pressure valve accordingly
(approx. 2,0 -2,5 bar).
Uses:
- for very thin material
- for very small lettering (e.g. 0,5 mm lettering height)
- to avoid material warping at the displacement point

Safety
Translation of the
Original Operating Instructions
00.02 Page 17 of 29
Multi-Marker
Normal lettering – medium depth – light needle component
Needle spacing approx. 1 mm to 1,5 mm above the material surface.
Pressure approx. 2,5 bar (material dependent).
Uses:
- for the most common marking types with character height > 1 mm
Needle frequency
The needle frequency in Hertz (Hz) indicates how often the needle is
extended per second.
Examples:
10 Hz, the needle is extended 10 times per second (very slow).
50 Hz, the needle is extended 50 times per second (medium).
100 Hz, the needle is extended 100 times per second (fast).
The lower the Hertz number, the fewer dots are marked! If you also
increase the marking speed, even fewer dots are marked. This pro-
duces “stress-free” marking for the material.
Vice-versa, the higher the Hertz number, the more dots are marked.
Reducing the speed results in even more dots, producing a more de-
tailed marking.
Standard lettering with the Multi-Marker is produced with 80 Hz.
Speeds
The speeds are stated in millimetres per second (mm/s). The marking
speed is the time in which the needle moves during the marking pro-
cedure.
A speed of 10 mm/s is sufficient for standard lettering.
The fast speed is the distance between the zero point to the start of
the lettering, between the individual vectors within a character and
between the characters. The fast speed should be identical with the
marking speed, but can be increased. The maximum fast speed
should not exceed a speed of 60 mm/s.
The reference run describes the movement of the needle to the ref-
erence position and should not exceed a speed of 40 mm/s.

00.02 Page 18 of 29
Multi-Marker
Pulses
The pulses are the times in which the valve opens and closes. These
times are stated in milliseconds (ms).
The first impulse provides the needle with enough air to penetrate the
workpiece with enough depth at the first point after the resting posi-
tion. If the time is set too high, the first puncture is clearly visible. In
standard lettering, the time of the first pulse should be clearly less
than the following pulses or be suppressed completely (1 ms).
For the following pulses, the needle is already moving so it does not
need so much air as for the first time. For standard lettering the time
should be 2.9 ms.
Waiting Time Start
Here you can adjust whether the needle should move straight away
or wait briefly. The standard setting is 1 ms. This function is only im-
portant for very special marking tasks, e.g. for the 2D matrix code.
Waiting Time Stop
Similarly to the waiting time start, here the needle waits after the
moved vector. The setting for standard lettering is 1 ms.
Needle
The standard scope of supply includes a soft spring with a light nee-
dle with a 118° tip. Many tests have revealed that this generally pro-
duces the best results. However, it is not possible to generalise here
because the marking results depend on the material of the workpiece
being marked, and on the character size. The needles are made of
carbide and can be reground using a diamond wheel if necessary.
Our needles are available with a tip geometry of 60°, 90° and 118° -
depending on the application. We can produce other tips on request.
Needle Needle Geometry Radius
3 mm 6 mm 60° R = 0,3 mm
3 mm 6 mm 90° R = 0,5 mm
