The reduction of manufacturing costs and improved productivity are often driven by the development of machine tools. Indirectly, these machine tool improvements are fuelling the creation of new machining strategies, particularly in the area of milling.

WNT is leading the way in developing new cutting tool strategies to make the most of machine tools that have higher spindle speeds, but maybe less torque, following the demise of the traditional gearbox in favour of spindle motors. While high speed and low torque is ideal for finishing cuts, when it comes to high volume metal removal issues may arise. It is here that WNT&rsquos HFC range of indexable cutters can play a significant role.

Cutting tool manufacturers have created ranges of tools capable of machining at elevated spindle speeds and at low depths of cut,says Adrian Fitts, Business Development Manager, WNT (UK).

This resulted in the strategy known as high speed machining (HSM) and while suitable for finishing components, it has limitations when large volumes of material have to be removed. WNT is now focussing attention on actual metal removal rates and a change in emphasis to high performance machining with the indexable HFC Highlight range of cutters.

At the heart of high performance milling is the cutter geometry, whether indexable or solid carbide. The cutters have to be designed in such a way as to place as little radial force on the machine spindle as possible and the design takes its cue from cutters using button-style inserts.

'Originally, indexable milling cutters were available with a 90 degree or 45 degree approach, which are fine when used on a heavier duty machine tool,'says Adrian Fitts. 'With a 90 degree approach cutter all of the cutting forces are radial and have the effect of trying to pull the cutter out of the spindle. When a 45 degree cutter is used the forces are divided between radial and axial creating a much softer cutting action. However, the arrival of button s meant that virtually all of the cutting forces are axial, up to a certain depth of cut.'
