1.8.3 Control technical protection
WARNING!
If you bypass a controller you endanger yourself and other persons working on the CNC
machine.
injuries due to tools, workpieces or fragments hereof which are flying off at high
speed,
contact with rotating parts,
fatal electrocution,
pulling-in of clothes.
If you bypass a controller in exceptional cases (e.g. during electrical repairs) short term you
must continuously monitor the CNC machine during this time.
1.8.4 Polycarbonate windows
Polycarbonate windows which have a safety-critical function with respect to ejected parts, must
be visual inspected by the customer responsible personnel at regular intervals to guarantee the
operational safety of the CNC machine.
Polycarbonate windows are subject to an aging process and are classified as wear parts.
The aging 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 age-
ing, i.e. deterioration of the mechanical properties (brittleness). Coolant vapours, detergents,
greases and oils or other corrosive substances from the operator side can also lead to a deteri-
oration of the polycarbonate windows. The result is a reduced parts retentivity of the polycar-
bonate windows.
