KNUTH NUMTURN 500/1000 FA HORIZONTAL MACHINING CENTER

Technical Description

The KNUTH Numturn 500/1000 FA is a CNC horizontal flat-bed lathe engineered for flexible single-part and batch production of large workpieces. This machine features a single main spindle with a maximum turning diameter of 20 inches and a maximum turning length of 30 inches, accommodating substantial components with a 10-inch chuck diameter. The spindle operates at speeds up to 2,000 RPM with 20.10 HP motor capacity, delivering robust cutting performance for demanding applications. The machine accommodates simultaneous use of two cutting tools, enhancing productivity through parallel operations. With a Z-axis travel of 36 inches, this lathe provides extended machining length capabilities for complex part geometries. The system utilizes an 8-station servo-driven turret with hydraulic clamping as standard equipment, ensuring maximum flexibility and rapid tool changes. Precision is maintained through high-accuracy spindle bearings and a rigid machine structure, with repeatability specifications of ±0.005-0.008 mm depending on axis. Rapid feed rates reach 4,000 mm/min on the X-axis and 8,000 mm/min on the Z-axis for efficient non-cutting movements. The machine integrates a hydraulic 3-jaw chuck, automatic central lubrication system, and Fagor 8055i CNC control for intuitive operation. This configuration makes the Numturn 500/1000 FA ideal for job shops and contract manufacturers requiring precision turning of medium to large components with minimal setup time.
