Heavy-Duty 4 to 6-Axis CNC Milling Machines with Integrated U-Axis Facing Heads for Global Precision Manufacturing
Nanjing Fortis Storage Equipment Manufacturing Co., Ltd. delivers a comprehensive lineup of industrial horizontal CNC machining centers equipped with integrated U-axis facing heads. Engineered for heavy metal removal, complex contouring, and strict geometric accuracy, our equipment lineup covers workpiece turning capacities from 350 millimeters up to 3,000 millimeters in diameter.
Unlike standard horizontal CNC mills that require separate turning lathes or auxiliary facing attachments, our dual-spindle architecture combines high-torque milling quills with specialized U-axis contouring heads. This allows global manufacturers to perform turning, facing, threading, and multi-axis milling operations on stationary parts in a single machine setup.

By maintaining a stationary workpiece while driving CNC tool movements, machines built by Nanjing Fortis Storage Equipment Manufacturing Co., Ltd. execute 9 critical metalworking functions with high precision:
Advanced multi-axis CNC interpolation creates complex curved profiles and precise geometric contours. The horizontal orientation ensures optimal chip clearance, preventing re-cutting and delivering smooth surface finishes on aerospace housings and automotive components.
With the workpiece firmly clamped, the integrated U-axis head rotates the cutting tool around the component. This setup achieves superior concentricity without requiring heavy parts to spin on traditional lathe chucks, enhancing shop floor safety.
The rigid dual-spindle construction provides vibration-free boring operations across long tool extensions. Ensures tight dimensional tolerances on engine blocks, pump casings, and high-pressure oilfield cylinders.
High-torque milling quills handle aggressive metal removal rates in tough alloys like Inconel, stainless steel, and titanium. Provides excellent rigidity during face milling, end milling, and slotting.
Integrated facing heads ensure outstanding surface flatness and squareness across wide flange faces, valve seats, and sealing surfaces, eliminating leak paths in critical pressure-containing equipment.
Executes rear-surface facing operations in the exact same clamping setup as front-face operations, guaranteeing perfect parallel alignment. Single-point threading features allow custom thread cutting on oversized diameters.
Evaluating total cost of ownership (TCO) requires assessing long-term operational productivity rather than initial equipment cost alone. Nanjing Fortis Storage Equipment Manufacturing Co., Ltd.'s horizontal machining centers deliver measurable ROI through reduced labor requirements, minimal scrap rates, and reduced facility footprint.
By replacing multiple single-purpose machines (such as standalone vertical turning lathes, horizontal boring mills, and radial drills) with one multi-function horizontal center, manufacturing plants realize significant production advantages:
Every machine manufactured by Nanjing Fortis Storage Equipment Manufacturing Co., Ltd. is backed by robust engineering support, comprehensive operator training programs, and available on-site maintenance services to ensure uninterrupted uptime worldwide.
An integrated U-axis facing head is built directly into the machine's spindle casting with dedicated CNC servo control. Unlike bolt-on facing attachments, it offers full CNC program control, high rotational speeds, automatic tool changing capability, and heavy rigid cutting performance.
Spinning large, heavy, or unbalanced castings on a conventional lathe creates high centrifugal forces and safety hazards. By holding the part fixed on a rotary table and spinning only the tool, Nanjing Fortis Storage Equipment Manufacturing Co., Ltd. machines deliver consistent concentricity and significantly safer operation.
Yes. Our machine structures utilize heavy cast iron frames with rigid box ways or linear guide options, paired with high-torque direct-drive spindles designed specifically for tough aerospace and oilfield superalloys.
