QL-MillBridge 450 Precision Vertical Turret Milling Machine
Heavy-duty industrial vertical turret milling machine with 12″ × 50″ table, 3 HP spindle motor, R-8 taper, factory-installed DRO, X/Y/Z power feeds, and air power drawbar. Designed for precision machining, fabrication, and maintenance operations in demanding workshop environments.
OVERVIEW
Description
The QuakeLogic QL-MillBridge 450 Vertical Turret Milling Machine delivers reliable performance for industrial machining and fabrication environments. Built with rigid cast-iron construction, it reduces vibration and maintains dimensional accuracy during heavy cutting operations.
In addition, the machine includes a factory-installed Digital Readout (DRO), X/Y/Z power feeds, and an air power drawbar. As a result, operators can change tools quickly, monitor positioning accurately, and increase workflow efficiency.
Moreover, the 12″ × 50″ precision-ground table provides generous workspace for medium to large components. With 33″ X-axis travel and 17.5″ Y and Z-axis travel, the QL-MillBridge 450 supports a wide range of fabrication, maintenance, and repair applications.
The 3 HP spindle motor delivers consistent torque across a 50–4,500 RPM speed range (Hi/Lo configuration). Therefore, users can perform drilling, boring, and milling operations with controlled material removal and repeatable results.
Because the system arrives fully configured and installation-ready, facilities can integrate it immediately into existing workshop operations. Furthermore, its integrated lubrication and drive systems support continuous-duty performance in demanding industrial settings.
