5.9 Adjusting the engraving depth
The engraving depth is determined by means of the depth adjuster on the engraving
spindle. Different script widths for the engraving are attained as a function of the width
and grinding angle of the engraving needle used, as well as the penetration depth into
the material.
For normal use we recommend the use of engraving needles with a grinding angle
of 15°.
These are available in widths of 0.2; 0.3; 0.4;
0.5; 0.7; 1.0 mm.
Special shapes are available on request.
The examples shown will give you an idea of
the different results of the engravings.
5.9.1 Engraving depth indicator
The setting of the engraving depth is carried out by rotating the
depth adjuster. By turning it to the right, the depth of the engraving
is increased, and by turning it to the left it is reduced.
When you actuate the depth adjuster, you will feel
a latching engagement.
With each engagement, the engraving needle is set higher or lower by 0.05 mm. Once
you have turned the adjuster by one revolution to the right, you will have
reached an engraving depth of 1 mm
(20 latch engagements of 0.05 mm each).
You can read off the depth on the engraving depth indicator on the
left next to the engraving spindle.
Caution: The tips of the engraving needle are highly sensitive and must be
treated very carefully. Avoid damaging the tips. If they are damaged, the quality
of the lettering will be severely impaired.
