Information on request
Accuracy
-
Goniometric measurements : ±0.01°
-
Ingot orientation process : better than ±0.05°
​
Software
​The software performs the orientation calculation in such a way that the ingot remains horizontal on the saw holder.
The operator is guides by the software during the orientation process.
Locks inhibit process progress until proper action is taken.

Configurations
The GM.SI series X-ray goniometer systems are designed for operation in combination with grinding equipment. The flat or notch orientation position found on the X-ray machine must be transferres to the grinder.
-
Several orientation transfer configurations can be offered to suit most grinding and ingot holding systems.
