Double Column Machine Center Descripition
The gantry machining center refers to the machining center in which the axis of the Z axis of the main shaft is perpendicular to the table. Especially suitable for machining large workpieces and workpieces with complex shapes.
CNC Gantry Machine Structure Characteristics
① A 500x500mm square ram structure
The machine is equipped with a four-sided restraint quenching guideway and a dual-cylinder nitrogen balance device, ensuring high overall rigidity and offering robust cutting capabilities with consistent precision.
② Italian BF gearbox
Featuring high-performance speed and low noise levels, this gearbox expands the constant power range of the motor and is designed for easy installation. It is compatible with a variety of motor series and can handle high-torque applications.
③ Fully automatic side milling head
The transmission gear is a Gleason spiral bevel gear, ensuring stable and precise transmission. It boasts a long service life. The internal transmission key of the milling head is a heat-treated component, minimizing backlash.
