Very short cycle times are achievable when they are used on sliding-head lathes, and the process offers other significant advantages over single-point thread cutting.
With its base carriers and ring cassettes, the new type M271 modular tool system offers a multitude of combinations tailored to the various Swiss-type lathes and drive units on the market.
The S271 system allows for a choice between conventional whirling with six or nine indexable inserts per ring cassette or the new Horn turbo whirling method, which uses nine precision-ground, double-edged indexable inserts. Three are for roughing, the remainder for finishing inserts, and all are tailored to the thread profile and material to be machined. Each cutting edge is subject to equal load, an additional factor in extending tool life.
A Torx screw, achieving maximum rigidity and precise indexing, means that the inserts are held accurately in place. That means handling is optimised during insert replacement in the new modular whirling heads or conventionally in Mono block tools
A tool configurator available at the Horn website supports choosing of the right combination of machine, drive unit and tool. The correct cutting data is also provided, thanks to the new HCT cutting data calculator, which can be accessed via the same page.
