Iscar adjustable Milling Cutters

Iscar recently made public a new family of High Speed Milling adjustable endmills and facemills that will advance milling of aluminum, non-metallics, cast iron and hardened steel. This should prove specially valuable in the automotive and aerospace industries.

The cutters are dynamically stabilized and precisely tailored to work with polycrystalline diamond (PCD) or cubic boron nitride (CBN) inserts. The use of these inserts will exceedingly improve surface finish. Conventional HSM-rated HELIMILL carbide inserts will likewise work with these tools. Internal coolant holes allow cooler cutting face and enhanced chip discharge 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 presented in HSK A63 shanks in four diameters starting from 25 to 50 mm. Iscar Facemills designated F90AD cover the 50 to 80 mm diameter range are available in 4 sizes.

When used with Iscar HELIMILL carbide inserts, the adjustable high speed milling cutters deliver a invariable cutting action at lesser cutting forces. HELIMILL inserts' helical cutting edges slowly enter the work piece reducing 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 applied for roughing and finishing operations. Due to their variable pitch they feature excellent chatter dampening ability. These endmills are an good resolution for low power machines by increasing their material removal rate and eliminating vibration. They can be utilized for full slot machining of up to 2XD with solid carbide endmills.

Iscar's CHATTERFREE endmills raise material removal rate and cut down cycle time in nearly all milling operations. Their special ground geometry provides fantastic 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 wide range of hard-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 exceptional 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 distinct milling cutters for semi-finishing and finish machining on cast iron. The insert features a 0.8 mm corner radius and a honed cutting edge (0.03 mm). It can be used on the standard F90AD...-SFR or the E90AD ...-HSK63-S axially adjustable milling cutters.

By adjusting the axial position of the inserts, it is feasible to obtain a 0.3-0.7 µm surface finish. IB85 is a fine grain polycrystalline cubic boron nitride grade. The small grain size enables grinding a tremendously sharp cutting edge and achieving high surface quality, which allow for excellent tool life. The IB85 grade can be used for machining a wide range of difficult to machine material at high cutting rates and provides excellent 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 and heat resistant alloys.
