Knuth PORTALO B 8025 VERTICAL MACHINING CENTER

Technical Description

The Knuth PORTALO B 8025 is a heavy-duty vertical machining center engineered for large-scale production work. Featuring a substantial work table measuring 315 inches by 83 inches, it accommodates workpieces weighing up to 132,000 pounds, making it suitable for aerospace, automotive, and industrial component manufacturing. The machine utilizes a BT50 spindle with a maximum speed of 6,000 RPM and delivers 56.30 horsepower at 30-minute rating, with an optional 37.55 horsepower configuration for varied cutting requirements. The three-axis CNC system provides exceptional travel distances: 98 inches on the X-axis, 323 inches on the Y-axis, and 47 inches on the Z-axis, enabling machining of long workpieces in a single setup. All axes achieve rapid traverse rates of 591 inches per minute with matching cutting feed rates, ensuring efficient material removal and reduced cycle times. The integrated 20-tool magazine with a rapid 6-second tool change time minimizes non-cutting time and maximizes productivity. Optional accessories include support and rotary tables, as well as a pallet changer system, allowing flexible workholding and continuous production workflows. The machine's rigid construction and high-performance spindle combination deliver precision machining capabilities while handling demanding production requirements. This configuration positions the PORTALO B 8025 as an ideal solution for manufacturers requiring substantial capacity, speed, and accuracy in large-component machining operations.
