Special Features

Grinding machines need great amounts of grinding medium and grinding oil. The oil includes fine abrasive debris, which may cause great damage to the pane.

It must be taken into consideration that there is a great amount of grinding emulsion. This substance may have high eroding effects on the window, which may cause a reduction of thickness of the polycarbonate pane by polishing – without this effect being visible. This cannot happen to a glass pane, since the glass has been ground and will break sometime
For this reason, a composite of glass and polycarbonate should be preferred in grinding machines.
If there is no direct impact and the grinding emulsion that hits the window is quite clean, there are no greater objections against the use of an indicator foil as a substitute of the glass pane.
