Product Briefing Outline: Arnold Gruppe has launched a new generation of combined surface and chamfering grinding machines. The Type 72/865 is specially designed for low and medium range brick production capacities up to 150MWp, which is claimed to significantly reduce production costs whilst increasing overall wafer quality.
Problem: With extensive improvements in the area of material and construction, the process reliability of this new generation of machines has been improved even further, to significantly reduce production costs whilst increasing quality.
Solution: The 72/865 is filled with mineral cast, which provides a by a factor of ten improved machine rigidity and increased noise suppression. A new coolant supply with a pressure of up to 25bar additionally provides optimal process cooling and at the same time reduces the water consumption by approx. a third. This way optimum process reliability, shorter processing times and more precise brick production can be guaranteed, according to the company.
Applications: Multi- and mono-crystalline silicon blocks up to 500mm length (wafer manufacturing chain).
Platform: An option available for the Type 72/865 is the data-base based and via web-browser controllable software tool ARPAT(R), which was developed by Arnold is used for the acquisition, analysis and storage of the process data provided by the combined machine.
Availability: It be first introduced into the market at the EU-PVSEC 2010 in Valencia and is available worldwide from January 2011.
