OKK VB53 ALPHA VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features robust travel capabilities with an X-axis travel of 41.34 inches, Y-axis of 20.87 inches, and Z-axis of 20.08 inches, allowing for substantial workpiece manipulation. It is powered by a 14.9 kW (approximately 20 HP) motor, supporting spindle speeds up to 20,000 RPM for high-precision, high-speed machining operations. The machine is equipped with a 30-tool automatic tool changer, enhancing production efficiency through quick tool swaps. The worktable measures 49.61 inches in length and 23.62 inches in width, supporting a maximum load of 2,646 lbs, suitable for heavy and large parts. The spindle clearance ranges from 5.91 to 25.98 inches, accommodating tall workpieces. Feed rates across all axes vary from 0.04 to 787 inches per minute (IPM), with rapid traverse rates up to 787 IPM, optimizing throughput and cutting efficiency. Coolant is delivered through the spindle to maintain tool life and surface quality during cutting. This machine operates on a 220V three-phase, 60 Hz electrical supply and has accumulated 4,579 machine hours. Its footprint is approximately 99 inches by 99 inches with a height of 115 inches and a total weight near 15,000 lbs, reflecting a stable and rigid construction suitable for demanding CNC milling applications. These specifications support the machining of complex, large-scale components with diverse materials requiring high spindle speeds and tool versatility.
