A Couple Of The Countless Improvements In Carbide Inserts Coming From Iscar Over The Last Decade



Iscar is announcing a brand new unique milling system with tangential, clamped, butterfly-shaped LNKX carbide inserts. The butterfly-shaped insert has significant advantages in comparison to the current flat, square shapes. The new geometry has more cutting edges, positive rake face, decreased cutting forces resulting in elevated performance. The carbide inserts are screw-clamped on the border of different milling cutter types, providing unmatchable conditions also for heavy-duty applications with excellent surface quality, saving additional finishing operations. End mills are available for 90 degree shoulder milling and for facing with 45 degree lead angles.

Each carbide insert has eight cutting edges, 4 for right-hand and four for left-hand cutting, enhancing the economy of use. The two, toward-center-slanted cutting edges furnish on one side strong and accurate clamping of insert in the tool body, and on the other side, the positive axial rake angle. The use of this positive axial rake composition decreases the cutting forces due to softer cut and easier penetration into the material, as well as changing force direction which is mandatory for use on modern machining centers with pallet systems less stable than on the classical transfer lines.

In normal applications like in the automotive industry, the depth-of-cut is less than thirty thousandths of an inch providing the use of all eight cutting edges of the Tangmill carbide inserts. Furthermore, in the automotive industry it is normal to use a pair of cutters, one for right- and one for left-handed operations, which means that all 8 cutting edges of the Tangmill inserts can be applied.

New ISCAR UPGRADES for Fast Metal Removal

Newly born advancements coming from the headquarters of Iscar, delivering the new Upgrade campaign, which guarantees that they are looking toward the future. The new Upgrade movement, scheduled to be released at the end of year 2008, will offer completely new tools for milling, turning, hole making and multifunction operations, complementing the FMR (Fast Metal Removal) tool families with one aim in mind - to increase productivity on the shop floor and to expand profits.

Iscar's feature for this year, with no doubt, are the new coatings, new substrate compositions, new cutting edge geometries, new sizes, new tangential clamping mechanisms and new coolant nozzle features. Iscar's future trends unite new carbide insert grades for efficient and cost-effective machining, more cutting edges to each insert and upper-level tangential clamping mechanisms which can significantly diminish the cutting forces. The introduction of the AL-TEC, PVD coating largely for nodular cast iron, a-TECH, CVD coating chiefly for grey cast iron and the DO-TECH, dual CVD PVD coating for enhanced strength will refashion the way manufacturers machines cast iron. Furthermore, Iscar offering mini inserts is an alternative trend within the Upgrade campaign, referring to reducing the sizes of the Tangmill carbide inserts into Minitang, in order to facilitate fine pitch configuration which will expedite feed rates. In addition, the compact size of the carbide inserts and their tangential position in the pockets allow a much bigger core diameter, in terms of tool design, when compared to regular radially oriented inserts.

Revolutionary End Mills Coming From Iscar Will Expand Productivity While Shrinking 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.
