Adding an edge to traditional inserts boosts productivity
Geometry provides increased stability, precision
Furthermore, the three-edged insert has a stronger structure and its clamping into the pocket features high rigidity, Iscar said. The advanced cutting geometry of the insert results in a precise 90° shoulder and a wiper flat provides excellent surface finish, according to the supplier, which added that the Heliqmill 390 tools have exhibited impressive ramping-down abilities.
The new tools are intended for machining shoulders, slots and planes. In addition, Iscar pointed out that they can be a good choice in milling surfaces, ramping-down or helical interpolation such as pockets or cavities. The tools are available as endmills with shanks and face mills with a central bore.
The best of both worlds for the optimum result
The line incorporates all the advantages of Helimill, the company said, along with all the added advantages of an extra cutting edge, a more robust design, improved reliability and added accuracy, which provide increased performance. The result is milling of true 90° in combination with an improved cost per cutting edge since the inserts cost they same as their dual-edged HM90 precursors.
The inserts are produced from the company’s Sumo Tec carbide grades, which is said to contribute significantly to their ability to increase productivity.
