Iscar Recently Made Public Numerous Original Lines To Increase Their Family Of Milling Cutters

Iscar adjustable Milling Cutters

Iscar recently released a new family of High Speed Milling adjustable endmills and facemills that will improve milling of aluminum, non-metallics, cast iron and hardened steel. This should prove especially helpful in the automotive and aerospace industries.

The cutters are dynamically balanced and precisely designed to work with polycrystalline diamond (PCD) or cubic boron nitride (CBN) inserts. The use of these inserts will considerably enhance surface finish. Regular HSM-rated HELIMILL carbide inserts will also work with these cutters. Internal coolant holes permit cooler cutting face with enhanced chip expulsion and built-up edge resistance. The insert pockets feature a flexible rear stopper, allowing for axial positioning of the cutting edge within 0.002 mm.

Iscar's endmills designated E90AD are available in HSK A63 shanks in four diameters from 25 to 50 mm. Iscar Facemills designated F90AD cover the 50 to 80 mm diameter range are available in 4 diameters.

When utilized with Iscar HELIMILL carbide inserts, the adjustable high speed milling cutters produce a fluid cutting action at lesser cutting forces. HELIMILL inserts' helical cutting edges gradually enter the work piece lowering the impact load on the cutting face.

CHATTERFREE Solid Carbide Endmills

Iscar is expanding the tremendously successful CHATTERFREE solid carbide 4 flute endmill family with the addition of smaller (3, 4 and 5 mm) and larger (25 mm) diameters. The new solid carbide endmills are utilized for roughing and finishing operations. Due to their variable pitch they feature outstanding chatter decreasing capability. These endmills are an terrific solution for low power machines by increasing their material removal rate and eliminating vibration. They can be used for full slot machining of up to 2XD with solid carbide endmills.

Iscar's CHATTERFREE endmills maximize stock removal rate and cut down cycle time in nearly all milling operations. Their distinctive ground geometry provides exceptional surface finish and prolonged tool life, while machining at high material removal rates.

New ID5 PCD and IB85 PCBN Tipped Milling Inserts

Iscar is adding a revolutionary TANGMILL ID5 PCD wiper insert and 2 HELIMILL inserts tipped with IB85 PCBN, for machining cast iron and a extensive range of difficult-to-machine metals at high cutting rates. The new LNAR 1106PN-R-S-W ID5 PCD tipped wiper insert has a extremely large frontal radius and sharp cutting edge. It provides a consistent clean-cut edge and outstanding surface finish of less than Ra 0.3 µm. Iscar's new HELIMILL insert ADKW 1505 PDER IB85 has an IB85 PCBN brazed tip and can be used on 90 separate milling cutters for semi-finishing and finish machining on cast iron. The insert incorporates a 0.8 mm corner radius and a honed cutting edge (0.03 mm). It can be used on the conventional F90AD...-SFR or the E90AD ...-HSK63-S axially adjustable milling tools.

By adjusting the axial position of the inserts, it is conceivable to achieve a 0.3-0.7 µm surface finish. IB85 is a fine grain polycrystalline cubic boron nitride grade. The compact grain size enables grinding a extraordinarily sharp cutting edge and accomplishing high surface quality, which allow for excellent tool life. The IB85 grade can be used for machining a wide range of tough to machine material at high cutting rates and provides remarkable tool life. IB85 contains 85% PCBN with Al Co and W binder.

It is a very strong and tough material which can be implemented for heavy roughing and interrupted cuts. The array of materials covered by IB85 encompasses hardened and cast steel of over 45 HRc, grey and nodular cast iron, powder compacted and sintered metals as well as heat resistant alloys.
