The Cyclo Cut Max-Flute high-performance end mills from MAG are designed for roughing titanium, Inconel and other high-temperature alloys.

It has a 16-flute design capable of high removal rates at low torque.

The high-density end mills run at 2037rev/min and 231ipm to achieve removal rates of up to 8in3/min with only 25ft/lb of torque and 9hp.

When cutting titanium 60-70 per cent of the heat generated is normally transferred to the tool, reducing tool life.

Max-Flute tools use shallow, radial widths of cut, which transfers less heat to the cutting tool and allows higher surface speeds for roughing titanium, Inconel and other high-temperature alloys that have traditionally required high torque at low revs/min to achieve desired removal rates.

MAG will demonstrate the Max-Flute cutting titanium, Inconel and stainless steel on a MAG small CAT40 VMC at IMTS 2010.

Used in conjunction with Truemill software, Max-Flute end mills maintain a constant angle of engagement, making the radial cuts more consistent throughout the cutter path, increasing material removal rates and decreasing cycle times, while extending tool life.

Dan Cooper, Cyclo Cut product manager for MAG Regional Services, said: ‘The current approach to high-speed machining involves taking very light cuts.

‘The Max-Flute/Truemill approach enables the machine to make heavier cuts at high speeds and by using the maximum flute density available, maximum feed rates are achievable,’ he added.

Max-Flute tools are designed with a differential pitch on the tool flutes to break up harmonics and reduce chatter.

Cooper added: ‘Titanium is very prone to chatter, which affects part quality, and can cause unpredictable tool failure.

‘By using extremely high feed rates and light radial cuts, we can remove a lot of material with little risk of scrapping parts.’
