KNUTH NUMTURN 420 SI ECO VERTICAL MACHINING CENTER

This CNC vertical machining center features a main spindle capable of turning diameters up to 17.000 inches and lengths up to 36.000 inches, allowing for the machining of moderately large cylindrical parts. The spindle operates at a maximum speed of 3,000 RPM powered by a 10 HP motor, providing sufficient torque and power for a variety of cutting tasks. The machine supports simultaneous use of two cutting tools, enhancing efficiency for multi-step operations without tool changes. It has an X-axis travel of 8.700 inches for precise radial tool movement and a Z-axis travel matching the maximum turning length of 36.000 inches for axial tool movement along the workpiece. The Y-axis rapid traverse speed is 157 inches per minute, enabling quick positioning between cuts or milling operations. This three-axis configuration (X, Y, Z) allows for complex part machining, including off-center and angled features beyond traditional two-axis turning. Overall, this vertical machining center is well-suited for precision turning and multi-tool processing, balancing moderate size capacity with versatile axis control and strong spindle performance for diverse manufacturing applications.
