THREAD TURNING

Thread Whirling Tools

Thread whirling is a fast and accurate way to thread long, small diameter parts in exotic materials, such as titanium, and nickel-based alloys (Inconel®, etc.). Our family of thread whirling tools enables the production of small-diameter, long threads when used on Swiss-type machines.

Whirling inserts and holders are capable of producing a wide range of medical parts – such as dental implants and bone screws, automotive parts, and small parts for the semiconductor industry.

Features:

  • Increased productivity: Thread whirling is performed in a single pass (and permits operation under high feed rates), resulting in shorter machining times.
  • Very high surface quality and geometry accuracy: The use of multiple cutting edges, high concentricity, and ideal chip removal enables top-quality surfaces to be produced without burr.
  • Longer tool life: Whirling inserts have a stronger cutting edge than single-point tools, as cutter side clearance is achieved via whirling spindle rotation (instead of relieving material under the cutting edge).
  • Faster setup: Thread whirling eliminates the need for special support devices, reducing initial R&D costs.
  • Support for large helix angles: Large helix angles can be compensated by adjusting the whirling unit.
