Protective Windows for Machine Tools
For the protection of operators against the risk of ejected parts, SicurTec have developed a range of safety windows which meet the requirements of impact resistance according to European Norm EN 12415 (turning machines) and EN 12417 (machining centres) and provide long term clear visibility without ageing of the polycarbonate.

Spin Windows
High pressure coolant systems cause ‘blind’ windows. You can no longer monitor your set up and production process correctly. Rotating at over 2000 rpm, spin windows throw off coolant and chip debris.

DQR Precision Ltd offers Visiport Spin Window systems to provide clear visibility.


Visiport by T2K is a lightweight spin window which can be installed on glass or polycarbonate and is adaptable to numerous machine tool enclosures.
