Thread Whirling Tools
Thread Whirling is a fast and an accurate way to thread long, small diameter parts in exotic materials such as titanium, stainless steel and inconel. Cutting is the result of the whirling ring rotating eccentrically at high speed about the slowly rotating workpiece. The advancement of the workpiece rotationally and the advancement of the tool head longitudinally correspond to the thread pitch required. Advantages Thread Whirling offers several advantages over single point threading: Enables production of small diameter long threads when used on Swiss type machines. The thread whirling spindle works close to the guide bushing for increased support and rigidity. Increased Productivity Thread Whirling is performed in a single pass, resulting in a shorter machining time. This eliminates multiple passes required for a single point threading. Thread whirling allows working at high feed rates and consequently results in short cycle times. Very high surface quality and accurate geometry The use of 6 to 8 cutting edges, higher concentricity, special cutting edge geometry and ideal chip removal, enable top quality surfaces to be produced without burrs. Long tool life Whirling inserts have a stronger cutting edge than single point tools, since cutter side clearance is achieved by rotating the whirling spindle, not by relieving material under the cutting edge. Faster Setup Thread whirling eliminates special support devices and
expensive startup development costs. Compensation of large helix angles Large helix angles can be compensated by adjusting the whirling unit. Short Delivery Time Up to 3 weeks.
