The program on heat exchange method crystal orientation


Purpose: after growing the boule under the heat exchange method, we can orient C off-angle M45°under the 
X ray the boule and crystal bulk.
1. We add a set of x-ray device on DX-8BD400AG unit, that means the new unit has two sets of X ray device 
(the second set device fixed for the C orientation angle.)
2.The unit can measure the crystal specification: A orientation (height:500mm,diameter:400mm,weight:120kg.
It can orient the sapphire’s  A,C,R,M,N plane.)
3. First: Fix the crystal on the two-dimensional adjustment fixture, finished the orientation of A plane, then 
process the A plane. 
4. After you use the second set device to finished orienting C orientation, move the crystal on the cutting 
machine then orienting and cutting it.
5. After cutting, put the crystal on the machine to orient again. If the Angular deviation is too large too big, 
then you should use the crystal adjustment fixture to adjust the crystal again, and process it until it can be 
qualified.

The program on the mobile devices off-Angle 45 ° crystal orientation


 Purpose: after growing the boule under the kyropoulos method, we can orient C off-angle M45°under the X ray the 
boule and crystal bulk.
Ⅰ. boule C off-angle M 45°(The following pictures are for reference only)
1. DX-8BD400AHG
The DX-8BD400AHG can measure the crystal specification: A orientation (height:500mm,diameter:400mm,weight:
120kg.It can orient the sapphire’s  A,C,R,M,N plane.)
2.First: Fix the crystal on the two-dimensional adjustment fixture, adjust and orient the crystal ball’s A plane, when 
you orient it, you should adjust the X and Y axis of A orientation, when you get the ideal angle, you should turn to 
next step to process the A orientation.
3.Use the of-angle fixture to fix the crystal, directly orient it under the X ray, when you orient it, the unit display C 
off-angle M 45°。
4. After cutting, put the rough crystal bulk on the unit to orient. If the crystal angle is over tolerance, then you should
 use the crystal adjustment fixture to adjust the crystal again, and process it until it can be qualified.
(DX-8BD400AHG)
Ⅱ. mobile devices off-Angle 45 ° crystal bulk orientation (The following pictures are for reference only)
1. DX-7B-SJG
Orient the angle of processed crystal bulk and outsourced crystal bulk, the unit display the measuring angle.
 (The above function can be placed on DX –8BD400AHG unit.)
