A new family of high-speed milling (HSM) adjustable end mills and face mills from Iscar are designed to improve milling of aluminum, non-metallics, cast iron and hardened steel, especially in automotive and aerospace applications.
The dynamically balanced cutters are specifically designed to work with polycrystalline diamond (PCD) or cubic boron nitride (CBN) inserts, protecting their edges and delivering outstanding surface finishes. They also accommodate standard HSM-rated Helido 2000 carbide inserts.
In both the end mills and face mills, internal coolant holes ensure a cooler cutting face while improving chip evacuation and resistance to built-up edge, the company says.
Insert pockets in the cutters feature a flexible rear stopper, which can be adjusted by a slanted screw, enabling axial positioning of the cutting edge within 0.002 mm (00008 inches).
End mills, designated E90AD, are available with HSK A63 shanks in four diameter sizes from 25 to 50 mm (1.00” to 2.00”). Face mills, designated F90AD, cover the 50 to 80 mm (2.00 to 3.00”) diameter range, also in four sizes.
When used with Helido carbide inserts, the adjustable cutters are designed to deliver smooth cutting action with low cutting forces. The carbide inserts’ helical cutting edges gently enter the work a bit at a time, like scissors slicing into paper, to reduce impact loads at the cutting face.
