SandvikPrecise machining and extremely tight tolerances are particularly important in medical technology, for example in the manufacture of bone screws or other small medical parts and microcomponents. The fast and reliable production of threads is a particular challenge here. For this reason, Sandvik Coromant has now developed inserts and holders for the "Coromill 325" for use on Swiss-type lathes, which can significantly optimize production processes.

With Coromant inserts and taps for thread whirling, longer, narrower, and high-quality workpieces can be produced from existing blanks on automatic lathes - and at high metal removal rates. At the same time eliminates the need to purchase a special machine for thread whirling.

The indexable inserts in the swivel rings can be quickly and easily inserted and replaced. Thus, the operator only has to attach the swirl ring to the spindle, tilt the spindle in relation to the desired pitch angle of the screw and tighten the ring bolt. In order to start the cutting process, the eccentricity of the ring is programmed in relation to the thread diameter and brought swirl ring and workpiece in the same direction (synchronous milling) - through these few necessary handles, the set-up times are significantly reduced.
