During machining, chippings are produced that can be swirled around inside the machine. It can also happen that tensioned workpieces are loosened or a tool breaks off due to incorrect operation and flies through the workspace with great force.
Therefore, the use of a safety window is recommended to protect the operating personnel. If only simple polycarbonate windows are used in the equipment of machine tools, they quickly become brittle due to the permanent contact with coolants and lose their retention force.
For this reason, HEMA uses a combination of safety glass and polycarbonate for the manufacture of its machine safety glass.
In general, we recommend the replacement of machine safety windows after a period of use of 5 years based on the recommendations of the employers’ liability insurance association and the VDW.
