1. MORGANA The accurate solution for a perfect cut 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 E Control the flatness of the scaife mM Level tang plate and scaife mM 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 mM check the correct mounting of a stone in its holder in press pots for bottoms as well as for tops mM check the perpendicularity of the table to the index axis when initiating crown polishing claw system MORGANA The advantages of Morgana mM Easy to use E No size limits M Quick procedures mM Prepare benches and tangs in no time m Storage of the alignment data max 20 benches mM Easy and quick alignment of scaife2.
