Iscar Recently Made Public Several New Lines To Enlarge Their Family Of Milling Cutters
Iscar adjustable Milling Cutters
Iscar recently made public 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 specifically valuable in the automotive and aerospace industries.
The cutters are dynamically stabilized and especially tailored to work with polycrystalline diamond (PCD) or cubic boron nitride (CBN) inserts. The use of these inserts will exceedingly enhance surface finish. Standard HSM-rated HELIMILL carbide inserts will likewise work with these tools. Internal coolant holes permit cooler cutting face along with upgraded chip discharge and built-up edge resistance. The insert pockets have 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 four diameters.
When utilized 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 gradually enter the work piece diminishing the impact load on the cutting face.
CHATTERFREE Solid Carbide Endmills
Iscar is expanding the highly successful CHATTERFREE solid carbide 4 flute endmill family with the addition of smaller (3, 4 and 5 mm) and larger (25 mm) diameters. The completely new solid carbide endmills are used for roughing and finishing operations. Due to their variable pitch they showcase superior chatter dampening ability. These endmills are an excellent resolution for low power machines by increasing their material removal rate and eliminating vibration. They can be employed for full slot machining of up to 2XD with solid carbide endmills.
Iscar's CHATTERFREE endmills maximize material removal rate and reduce cycle time in nearly all milling operations. Their special ground geometry provides fantastic surface finish and long tool life, while machining at high material removal rates.
New ID5 PCD and IB85 PCBN Tipped Milling Inserts
Iscar is adding a new TANGMILL ID5 PCD wiper insert and 2 HELIMILL inserts tipped with IB85 PCBN, for machining cast iron and a broad range of hard-to-machine materials at high cutting rates. The new LNAR 1106PN-R-S-W ID5 PCD tipped wiper insert has a very large frontal radius and sharp cutting edge. It provides a uniform 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 includes 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 cutters.
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 hard to machine materials 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 employed for heavy roughing and interrupted cuts. The assortment 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.
