KNUTH NUMTURN 660/1000 FA HORIZONTAL MACHINING CENTER

The KNUTH Numturn 660/1000 FA is a CNC horizontal turning center designed for flexible production of single-part and batch manufacturing of large workpieces. This machine features a single main spindle with a maximum turning diameter of 26 inches and a turning length capacity of 29 inches, accommodating work pieces up to 12 inches in chuck diameter. The spindle operates at 2,000 RPM with 24.80 HP, delivering substantial cutting power for heavy machining operations. The machine incorporates dual simultaneous cutting tool capability, enhancing productivity through multi-tool engagement strategies. With 36 inches of Z-axis travel, the turning center provides extended workpiece positioning and tool clearance for complex turning operations. The Fagor 8055i CNC control system enables precise programming and automated operation, making the machine suitable for maintenance departments and specialized production environments. The rigid box-way machine structure ensures dimensional stability during heavy cutting cycles, while the horizontal spindle orientation facilitates efficient chip evacuation and operator access. An 8-station VDI tool changer with rapid feed capabilities—8,000 mm/min on the X-axis and 10,000 mm/min on the Z-axis—enables quick tool changes and efficient cycle times. The tailstock features hydraulic quill control with standard MT5 taper for consistent workholding. Measuring 4.3 meters in length with a total weight of 4,300 kg, this versatile turning center combines power, precision, and flexibility for demanding production applications.
