Polycarbonate windows
Polycarbonate inspection windows, which have a safety-critical protective function in respect of
flying parts, must be visually inspected at regular intervals by responsible personnel provided
by the customer in order to guarantee the operational safety of the milling machine.
Polycarbonate viewing panes are subject to an ageing process and are classified as wear
parts.
The ageing of polycarbonate windows can not be detected by visual inspection. It is therefore
necessary to replace the polycarbonate windows after a certain time.
Prolonged exposure from polycarbonate windows to cutting fluids can lead to accelerated
ageing, i.e. deterioration of the mechanical properties (brittleness). Coolant vapours, deter-
gents, greases and oils or other corrosive substances from the operator side can also lead to a
deterioration of the polycarbonate windows. The result in reduced impact resistance of the poly-
carbonate windows.
