KNUTH DL S 515/3000 MANUAL LATHES

Technical Description

The KNUTH DL S 515/3000 is a robust horizontal machining center designed for heavy-duty turning applications with a maximum turning diameter of 39.0 inches over the bed and a max turning length of 118.0 inches. It features dual main spindles, each powered by a 24.8 HP motor, capable of speeds up to 630 RPM, offering high torque and stable operation under heavy loads. The spindles are mounted on A2-11 tool carriers, ensuring compatibility with large-diameter workpieces and delivering precise rotational performance. The machine supports a maximum workpiece weight of 8,800 lbs and includes a travel of 10.0 inches on the Z1 axis, complemented by extended X-axis travel of about 20.5 inches and Z-axis travel up to 106 inches, facilitating versatile machining operations. The bed width of 24 inches and a gap bridge length of 19 inches provide rigid support for heavy workpieces, while the 3.9-inch spindle bore enhances stability during machining. Rapid feed rates reach approximately 70.87 inches/min on the X-axis and 143.31 inches/min on the Z-axis, contributing to efficient material removal and cycle times. The machine incorporates a manually shifted 4-step gearbox with frequency control for fine spindle speed adjustment and smooth start-up dynamics through a multi-disc clutch. Overall dimensions measure approximately 203 by 60 by 63 inches (LxWxH), with a weight near 14,960 lbs, emphasizing its heavy-duty construction intended for machining large, heavy components in industrial settings.
