A Few Of Improvements In Carbide Inserts By Iscar
Iscar is starting a completely new unique milling system with tangential, clamped, butterfly-shaped LNKX carbide inserts. The butterfly-shaped insert has notable advantages compared to the current flat, square shapes. The new design has more cutting edges, positive rake face, lowered cutting forces resulting in higher performance. The carbide inserts are screw-clamped on the perimeter of varied milling cutter types, providing optimum conditions also for heavy-duty applications with outstanding surface quality, saving further finishing operations. End mills are offered for 90 degree shoulder milling and for facing with 45 degree lead angles.
Each carbide insert has 8 cutting edges, four 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 dependable 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 diminishes the cutting forces owing to softer cut and easier penetration into the material, as well as changing force direction which is mandatory for use on up-to-date machining centers with pallet systems less firm than on the conventional 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 8 cutting edges of the Tangmill carbide inserts. Furthermore, in the automotive industry it is popular to use a pair of cutters, one for right- and one for left-handed operations, which means that all eight cutting edges of the Tangmill inserts can be applied.
New ISCAR UPGRADES for Fast Metal Removal
New 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, proposed to be made public at the end of year 2008, will offer revolutionary tools for milling, turning, hole making and multifunction operations, complementing the FMR (Fast Metal Removal) tool families with one aim in mind - to boost productivity on the shop floor and to raise profits.
Iscar's focus 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 functions. Iscar's future trends combine new carbide insert grades for effective and time-saving machining, more cutting edges for each insert and upper-level tangential clamping systems which can significantly diminish the cutting forces. The debut of the AL-TEC, PVD coating principally for nodular cast iron, a-TECH, CVD coating essentially for grey cast iron and the DO-TECH, dual CVD PVD coating for refined strength will revolutionize the way manufacturers machines cast iron. In addition, Iscar producing mini inserts is an alternate direction within the Upgrade movement, referring to decreasing the sizes of the Tangmill carbide inserts into Minitang, in order to assist fine pitch configuration which will accelerate feed rates. In addition, the compact size of the carbide inserts and their tangential location in the pockets make possible a much bigger core diameter, in terms of tool design, when compared to standard radially positioned inserts.
