GM.WS Series

Goniometer for ingot
Software Goniometer for ingot

â–     Ingot orientation prior to wire saw cutting

  • Sotfware assisted orientation process

  • Storage of measurement and orientation data

â–     Measurement and orientation of ingot axis

  • Special process and additional equipment available for preparation of "on-axis" OD grinding of ingots

       (Data sheet on request)​

â–     Determination of <110> directions on <111> ingots

  • 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.

​​

Models/capacities

  • Several models are available to cover a large range of applications with ingot diameters from 2" to 300mm and lenght up to 550mm

  • Special / customized models on request

  • Mixed dual-station versions, with above GM or GM.SI station as a second station

GM.SI Series

â–     Orientation measurements

  • Ingot flat

  • Ingot notch

  • Seed orientation (round or square seeds)

  • Wafer face

  • Wafer flat

â–     Orientation processes

  • Flat & notch on "as grown" ingots

  • Flat & notch on ground ingots​

  • Special orientations on various crystals

​

Models / Capacities

  • GM.SI 10 : Ingot diameter 75 to 250mm

  • GM.SI 12 : Ingot diameter up to 300mm

  • Ingot lenght up to max 800mm or 85kg

 

Options

  • Angular display of ingot rotation

  • Angular display options as above GM series

​

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. 

       Description of various procedures on request.​

  • Mixed dual-station versions, with GM or GM.WS station as a second station.

​

Performance

  • X-ray detection : ±0.01°

  • Orientation process :±0.03° to 0.05° , depending of configuration

  • Measurements : ±0.01° to 0.03°
