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 specifically valuable in the automotive and aerospace industries.

The cutters are dynamically balanced and especially designed to work with polycrystalline diamond (PCD) or cubic boron nitride (CBN) inserts. The use of these inserts will greatly increase surface finish. Conventional HSM-rated HELIMILL carbide inserts will also work with these cutters. Internal coolant holes permit cooler cutting face and improved chip expulsion 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 available in HSK A63 shanks in 4 diameters from 25 to 50 mm. Iscar Facemills designated F90AD cover the 50 to 80 mm diameter range are available in 4 diameters.

When used with Iscar HELIMILL carbide inserts, the adjustable high speed milling cutters deliver a smooth cutting action at low cutting forces. HELIMILL inserts' helical cutting edges slowly enter the work piece diminishing 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 latest solid carbide endmills are implemented for roughing and finishing operations. Due to their variable pitch they feature fantastic chatter dampening ability. These endmills are an outstanding resolution for low power machines by improving 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 increase stock removal rate and shrink cycle time in most milling operations. Their unique 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 new 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 particularly large frontal radius and sharp cutting edge. It provides a uniform clean-cut edge and excellent 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 different 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 possible to accomplish a 0.3-0.7 µm surface finish. IB85 is a fine grain polycrystalline cubic boron nitride grade. The minimal grain size enables grinding a exceptionally sharp cutting edge and achieving high surface quality, which provide excellent tool life. The IB85 grade can be used for machining a wide range of difficult to machine metal at high cutting rates and provides superior tool life. IB85 contains 85% PCBN with Al Co and W binder.

It is a very strong and tough material which can be put to use 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.

Iscar Releases A New Family Of Slitting Cutters Using Tang-Grip Technology And The Strength Of Sumo Tec Grades
Iscar now offers a family of high-performance slitting tools that combine the convenience and security of Tang-Grip clamping with the added durability of the new Sumo Tec insert grades. The concept, already proven successful in Tang-Grip parting tools, has now been extended to slitting cutters.

Some Improvements Have Enhanced Iscar's Line Of Indexable Endmills For Increased Productivity
Helido-Upfeed 04 Two years ago Iscar introduced the extremely efficient H600 indexable endmill line, based on conceptually new Helido-Upfeed double sided inserts with 6 cutting edges. The first insert launched was the H600 WXCU 0806..., which was designed for milling cutters in the diameter range of 50 to 125 mm.

A Few Of The Several Advancements In Carbide Inserts By Iscar
Iscar is introducing a new unique milling system with tangential, clamped, butterfly-shaped LNKX carbide inserts. The butterfly-shaped insert has significant advantages compared to the current flat, square shapes. The new geometry has more cutting edges, positive rake face, reduced cutting forces resulting in higher performance.

Cutting Edge Cutters And Carbide Insert Compositions From Iscar To Better The Machining Method
Iscar is introducing Penta 34 carbide inserts with a new PB chipformer. The PB chipformer features a single cavity with a positive rake, neutral shoulder angle, and a honed edge. It is actually a C-type chipformer with a different frontal edge.

The Latest In Carbide Endmill Architectures In A Lengthy And Productive Family From Iscar
Manufacturers and die & mold shops can eliminate chatter problems in many milling operations with Iscar's new Chatterfree endmills. The cutters' variable-pitch flute pattern eliminates harmonic vibration, the main source of chatter. This enables faster cutting and finer finish in rough or finish slotting, shoulder milling and cavity milling.
