Revolutionary tool turns cutting through 90 degrees

Mori Seiki and Kennametal have jointly developed a 'Spinning Tool', an axially loaded turning tool.

Compared with conventional methods, the Spinning Tool reduces tool tip temperature and tool wear, achieving new standards in high-precision, high-efficiency turning, it is claimed.

Benefits claimed for are:

? Improves productivity by 5 times*
? Extends tool life by 20 times*
? Dissipation of heat allows dry machining
? Synchronizes with the spindle, allowing elliptical machining
? Effective for machining difficult-to-cut material, such as nickel alloy or heat-resistant alloy

With a conventional turning tool, since the cutting edge is brought into contact with the workpiece from a perpendicular direction, forces cause the tool to flex. In contrast, with the Spinning Tool, the cutting edge is brought into contact from the cutting force direction - end on - so the cutting reaction acts along the centre of the tool back into the tool shank/toolholder, enabling more aggressive cutting to take place. The rotating tool tip avoids a single point being raised to a high temperature, reducing wear and extending tool life.

The Spinning Tool is intended to be mounted on lathe-type machines, like Mori Seiki's NL (Y-axis specifications) or NT models.
