Can diamond wire sawing be used for photovoltaic silicon wafers?

This paper reviews recent research on diamond wire sawing of photovoltaic silicon wafers and compares it with the loose abrasive wire sawing process from a standpoint of sustainable manufacturing.

How is diamond wire made?

Wire manufacturing The diamond wire is produced by coating high carbon steel wires with electroplated nickel, which binds the 8-12 Âµm sized diamond abrasives to the steel core wire [14, 36, 84]. The process has undergone improvements over the years.

Does diamond wire break-in affect process performance?

Other related work showed the diamond wire break-in during initiation of cutting, which impacts the process performance . Prediction of diamond wire wear along with total thickness variation, and lifetime estimation, has also been reported .

Is there a correlation between diamond wire wear and RV frequency?
