Iscar is introducing Penta 34 carbide inserts by having a new PB chipformer. The PB chipformer includes a single cavity by having a positive rake, neutral shoulder angle, and a honed edge. It is actually a C-type chipformer using a different frontal edge.

The revolutionary chipformer was designed for machining soft materials. It is an wonderful solution for parting bearing steel and other very ductile materials. It can be used at low feed: 0.03 to 0.10 mm/rev.

The combination of the completely new chipformer and IC908 grade provides excellent chip breaking and tool life results. The Penta 34-PB is available in a 1.5 to 3.0 mm width range, made from the resilient IC908 PVD coated grade. The completely new family broadens the application range of Iscar's most efficient grooving and parting PENTA 34 carbide inserts. The Penta 34-PB, when compared to a competitor's cutter, is a winning solution for machining every soft and ductile material.

Iscar's Upgrades for Parting

Iscar has developed a new family of reinforced Tang-Grip blades for the well-liked TRAUB (TNL and TNK models) and INDEX (MS18C model) turn/mill machines. These blades, due to their reinforced composition, can be employed in long overhang. Only the part of the blade required for penetration (cutting depth) has a reduced width. The remainder is thick, which provides improved rigidity and stiffness. These blades are an outstanding solution for parting and grooving between the main and sub-spindle of turn/mill machines. The single-ended insert has a substantially rigid clamping and therefore provides a very visible advantage over any other system.

Further additions to Iscar's Grip family are Do-Grip carbide inserts fashioned from the brand new Sumo Tec carbide grades: IC807 IC808 and IC830. The new Sumo Tec grades unquestionably extend insert life, due to the utmost advanced coating technology followed by a special surface treatment. This also provides upgraded tool life due to low surface stress and an uniformly coated top surface. The level surface contributes to smooth uninterrupted chip flow, less generated heat and less friction. The new process promotes toughness and chipping resistance and thus reduces friction and built-up edge. This in turn optimizes and prolongs tool life at increased machining conditions for all types of work piece materials. The new PVD process is constructed of Iscar's AL-TEC coating technology, utilizing the unique surface treatment.

Iscar's Chip Splitting Inserts
Iscar's unique HM90 APCR 220605-CS grooved carbide inserts put an end to chip crowding complications in rough milling of aluminum, where chips can pile up. They are a part of Iscar's growing Helialu HM90 line of inserts tailored particularly for aluminum milling. With two grooves pressed into every single polished cutting face, the inserts split aluminum chips into a manageable size for easy, dependable evacuation despite the application's characteristic high chip volume. The 22 mm inserts, each with 2 edges, are designed to expand metal removal over the comprehensive range of aluminum roughing conditions, from high power/low speed to high power/high speed. They work especially well with Iscar's cutting edge HM90 EAL/FAL...22 aluminum rough milling cutters. Besides reliably clearing chips, the inserts conserve power and trim down chatter in long-overhang setups. The inserts feature a cavity on the bottom to ensure correct mounting in cutter chip pockets outfitted with standard spring pins. For excellent chip control, Iscar endorses using the HM90 APCR chip-splitting insert only in cutters with an even number of flutes.

Iscar Recently Made Public A Variety Of New Lines To Continue Their Family Of Milling Tools
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 useful in the automotive and aerospace industries.

Brand New End Mills From Iscar Will Expand Productivity While Decreasing Costs
Manufacturers and die & mold shops can banish chatter problems in numerous milling operations with Iscar's new Chatterfree end mills. The cutters' variable-pitch flute pattern eliminates harmonic vibration, the primary source of chatter. This enables faster cutting and finer finish in rough or finish slotting, shoulder milling and cavity milling.
