Overview
Powered Gate Overview
The Dragon A400 Powered Gate allows the machine to process angle and channel material in
addition to round, square and rectangle material. Bend-Tech has found that to process angle
or channel material it is required that the Gate move in coordination with the Chuck. Without
a Powered Gate, angle or channel material cannot be held securely in the Gate. Customers
who want to process angle or channel material can purchase a new Dragon A400 machine
