Gortite, an A & A Manufacturing company, offers its NT automatic door opening system, which is designed for field- retrofit on existing machinery to boost productivity by automatically opening and closing machine tool doors. Their safe, ergonomic design protects the operators of automatic machining equipment from repetitive-motion injuries, the company says. The openers incorporate a pre-programmed control module that is designed for ease of use and automatically reverse when objects in their path are detected. They can be wired into the machine’s controller to close the door, or a simple on/off circuit can be used. The system also can feed back key outputs and messages to the machine controller.
The door openers open single or double doors, have unlimited travel distances and
are self-calibrating. Their fully electric operation requires no shop air, and they operate without extra limit switches, light curtains, pressure switches or photo eyes. An internal braking system engages in any stopped position. The door openers are designed for use on Brother, Bridgeport, Cincinnati, Daewoo, Fadal, Haas, Hardinge, Mazak, Mori Seiki, Okuma and many other types of machines.
