lead screw/rotor/drill rod/worm shaft/ processed on CNC whirling machine

The whirling is the high-performance helical machining solution which can be external whirling and internal whirling. External whirling can be used for workpieces of helical geometry like precision threaded spindles, worm gears, extrusion screws, screw elements and screw compressor rotors. Multiple-start threads can be obtained by subsequent processing of the individual threads or by whirling with synchronized axes. In addition, symmetric and asymmetric curve and rotational surfaces can be produced. Examples of application are lifting and main bearings, camshafts, eccentric screws, balls and polygonal profiles. Internal whirling can be used for machining the inner surfaces of hemispherical heads, pump housings and extruder barrels and the production of internal threads for nuts of any type and heavy workpieces such us turbine housings, reactor pressure vessels and press frames。
