Cutting

Pietta Glass Working

The glass cutting into small pieces is performed by a cutting bench, a numeric control machine which presents a fixed plane with a velvet covering and with holes to generate an air cushion (useful for the displacement of the glass).

Above this there is a movable bridge that provided by a glass cutter wheel of synthetic diamond makes engravings on the glass depending on the requested dimensions.

The optimization software is implemented in order to optimize the cut, avoiding waste to a minimum. The glass cut in this way will then be truncated by an attendant.

For laminated glass panels cutting is performed on both the top of the glass, while the polymer film holding the two coupled sheets (PVB or polyvinyl butyral) is cutted by a resistance, which dissolves the PVB allowing the opening of the cut.
