KNUTH NUMTURN 660/1000 SI HORIZONTAL MACHINING CENTER

Technical Description

The KNUTH Numturn 660/1000 SI is a horizontal CNC turning center designed for flexible production of single parts and batch machining of large workpieces. It features a powerful main spindle with a maximum turning diameter of 26.0 inches and a maximum turning length of 29.0 inches. The spindle includes a 12-inch diameter chuck and operates at speeds up to 2,000 RPM with a 24.8 HP motor, providing robust machining capacity. The machine supports a single main spindle design but includes capability for two simultaneous cutting tools, enhancing productivity for complex operations. The Z-axis travel is 36 inches, allowing significant machining length, while the system is controlled by a Siemens 808D Advanced TTL CNC unit, facilitating precise and efficient control. The machine incorporates a tailstock with a hydraulic quill for secure workpiece support. Its construction features a rigid bed and linear guideways to ensure stable and accurate cutting performance. This setup is well-suited for demanding turning operations requiring dynamic feed rates and precise positioning. Overall, the Numturn 660/1000 SI combines high torque, substantial working capacity, and advanced CNC control for versatile, high-precision horizontal turning applications.
