ROMI UT-1500/4000 CNC LATHE

Technical Description

This is a heavy-duty CNC turning center engineered for large-scale production machining applications. With a commanding 199.9 horsepower output, the machine delivers substantial cutting force necessary for demanding turning, boring, drilling, and threading operations on oversized workpieces. The 59.06-inch swing capacity accommodates large-diameter components, while the 157.48-inch machining length enables processing of extended cylindrical parts with precision. Operated by a GE-Fanuc 21i-TB CNC control system, the machine provides advanced programmable automation capabilities for complex part geometries and multi-axis operations. The maximum spindle speed of 200 RPM is optimized for heavy-duty cutting at lower rotational velocities, prioritizing torque over speed—ideal for rigid, powerful cuts in tough materials and large workpiece diameters. The machine frame construction emphasizes structural rigidity and thermal stability to maintain dimensional accuracy during sustained high-force operations. Its linear motion systems enable precise tool positioning along multiple axes, utilizing high-performance servo motors and ballscrews or linear motion components for micron-level accuracy. An integrated automatic tool changer streamlines production workflows by minimizing setup times between operations. This configuration makes the machine suitable for heavy manufacturing environments including aerospace, defense, energy, and large industrial component fabrication. The combination of substantial power, generous swing and length capacities, and robust CNC control creates a versatile platform for producing complex large parts with tight tolerances and superior surface finishes.
