The MAMMOTH PROKING PA-45 is a heavy-duty horizontal machining center designed for large workpieces with a maximum turning diameter of 34.250 inches and a turning length capacity up to 800 inches (optional). It features a robust main spindle with a 35-inch chuck diameter and a maximum swing of 44.750 inches, enabling machining of substantial parts. The machine is equipped with a single main spindle operating at 630 RPM with 20 HP power, with an optional upgrade to 500 RPM and 40 HP for higher torque applications. The tool handling system utilizes a slide-type primary tool carrier, supporting one simultaneous cutting tool, and the machine operates with 2 axes controlled for precise machining. The Z-axis travel is 60 inches standard, extendable to 800 inches for deep reach operations, making it well-suited for long or large components. This setup allows for high rigidity and precision in heavy machining tasks, emphasizing power and capacity over high spindle speed, typically optimized for lower RPM high-torque cutting typical in large-part horizontal machining centers. The machine's capabilities target industries requiring substantial turning and milling operations on large workpieces with demanding dimensional and power requirements. Its spindle specifications and travel distances make it a specialized solution for extensive horizontal machining needs.
