The accurate solution for a perfect cut
Introduction
Nothing is more important than accurate alignment
of polishing equipment to achieve the so sought-after
Triple Excellent diamond cut qualification. Perfect
proportions, symmetry and polish are non-negotiable
when selling a diamond at the best price. But to achieve
this level of perfection, the diamond polisher needs
to rely on his equipment. An accurate setting of the
polishing tang and bench is crucial to obtain the
highest level of accuracy.
Up until now, diamond polishers commonly use levels
to align tang plates and tangs. A perfect alignment of
the polishers’ equipment takes hours and tons of experience.
Today, HRD Antwerp offers a new solution: Morgana.
Morgana is a complete set of tools that helps the diamond polisher to align his polishing equipment.
How?
Morgana helps the polisher to:
• align the tang plate(s) on the mill according
to the scaife
• align facets to the scaife
• align the grain axis perpendicular to the scaife
• tilt the facet very accurately in a
predetermined angle
• check the setting of the stone in the tang
• check the angular scale of the tang

Principle
The innovative Morgana technology is based on the
reflection of a light beam on a surface. Its high-tech
system uses a set of cameras, light beams and calibration parts. The camera generates a light beam,
which is reflected by a flat surface (this can be a facet,
a mirror, a piece of polished metal or a piece of glass,
etc.). This reflection is shown as a point on the screen
and its relative position represents very accurate the
relative angle of the reflective surface (0,01 °). On top
of the tang a mirror is mounted, as reflective surface,
to replace the level. This tang mirror will be aligned
perpendicularly to the grain axis of the tang.
Different sets and applications
Basic unit
Morgana’s basic unit is a set for tang-calibration, consisting of:
• A table-unit with camera for facet adjustment
• A unit with camera for grain-axis-adjustment
• Tang mirrors
• A tool for calibration
• An angle setting control instrument
• A control unit and screen
What can it do?
• (Re)take a facet flat-on and align it on
the scaife fast and accurate
• Tilt a facet (within 0,01°) in a predetermined angle fast and accurate
• Align grain axis so that no false facet is polished by changing the polishing direction (‘in and out of the tang’)
and to obtain correct angles.
• Calibrate the angular scale of the tang

Tangplate alignment set
The tang plate alignment set is a set of tools that will
help the polisher to bring the tang plate on the same
water-level and in the same plane as the polishing
wheel (the scaife). It is additional to the basic unit, which
requires perfect alignment of the tang plate.
What can it do?
• Control the flatness of the scaife
• Level tang plate and scaife
• Adjust scaife height
• Check overall alignment of tang plate and scaife Calibrate all polishing benches
Online check of grain-axis alignment
(while polishing)
For this application, the camera is set in a holder on
the bench above the polisher’s tang, which needs to
be equipped with a tang mirror. Every time the tang
mirror is passing under the camera, the polisher can
check the inclination of the grain-axis and adjust if
necessary. When the inclination is ‘nil’, this means the
desired facet angle is achieved.
Additional accessories are available to:
• check the correct mounting of a stone in its holder
(in press pots for bottoms as well as for tops)
• check the perpendicularity of the table to the index
axis when initiating crown polishing (claw system)
