The EU PVSEC is not only an international expert congress for research and development, industry and application, it is one of the most important industrial fairs concerning photovoltaics.
The Arnold Group belongs to one of few internationally accepted full-service providers offering process- and automation technologies for the wide spectrum of silicon brick manufacturing from one source.
The specialist makes use of the international PVSEC forum to introduce new and technically innovative high-end machines and solutions with measurably high value for the customer.
Combination grinding machine
The focus of the company presentation is the live demonstration of the combined surface and chamfer grinding machine, type 72/865. This machine can already be used economically for small and medium sized brick production capacities. It is an ideal completion of the well approved stand alone machine for surface grinding and chamfer grinding supplied by the manufacturer Arnold.
With the assistance of the integrated process analysis tool ARPAT, current process data are collected, visualized and analyzed and are the basis for a continuous optimization of production and process parameters.
A process capability of > 1,67 cpk at a tolerance of +/- 0,05 mm can constantly be obtained and paves the way to get the required "Zero Error Strategy". This new machine is available starting from now.
Squaring saw
With the new squaring saw, type 72/476, the thin-blade cutting technology for manufacturing multicrystalline bricks – successfully established for years – is now adopted to the monocrystalline brick production. The sawing blade has a thickness of 1,5 millimeter. That means the kerf loss – compared with commercially available blade thicknesses of 3,5 millimeter – is more than halved.
This traditionally robust and reliable production technique guarantees high availability and a stable process. This new machine also available starting from now – stands out due to low tooling costs and simple operation.
Cropping saw
This new cropping saw completes the manufacturing process of monocry-stalline bricks. The machine works completely automatically from ingot loading till unloading of bricks. This machine will be available end of 2011.
