GDC20/25/35md Series CNC Movable Gantry Milling & Drilling Machine
Detailed Product Description
GDC series machines are designed with double headstocks to increase working efficiency greatly. Gear-box with characteristics of large torque in low speed and constant power in high speed is supplied for main transmission system; The movable bridge frame is designed with advanced synchro-driving technology used for transmission of gear and rack to secure high transmission accuracy. The machines can accomplish various drilling of all sorts of tube plate work-pieces in one time setting-up.
