A Couple Of Advancements In Carbide Inserts By Iscar Over The Years
Iscar is adding a new unique milling system with tangential, clamped, butterfly-shaped LNKX carbide inserts. The butterfly-shaped insert has noteworthy advantages in comparison to the current flat, square shapes. The new geometry has numerous cutting edges, positive rake face, decreased cutting forces resulting in greater performance. The carbide inserts are screw-clamped on the edge of various milling cutter types, providing unsurpassed conditions also for heavy-duty applications with superb surface quality, saving several other finishing operations. Mills are available for 90 degree shoulder milling and for facing with 45 degree lead angles.
Each carbide insert has eight cutting edges, four for right-hand and four for left-hand cutting, upgrading the economy of use. The two, toward-center-slanted cutting edges furnish on one side strong and definitive clamping of insert in the tool body, and on the other side, the positive axial rake angle. The value of this positive axial rake composition reduces 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 up-to-date machining centers with pallet systems less stable than on the traditional 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 used.
New ISCAR UPGRADES for Fast Metal Removal
New progress coming from the headquarters of Iscar, delivering the new Upgrade movement, which guarantees that they are looking to the future. The new Upgrade movement, scheduled to be released at the end of year 2008, will offer new tools for milling, turning, hole making and multifunction applications, 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 formations, new cutting edge geometries, new sizes, new tangential clamping mechanisms and new coolant nozzle functions. Iscar's future trends unite new carbide insert grades for effectual and cost-effective machining, more cutting edges to each insert and upper-level tangential clamping systems which will significantly decrease the cutting tension. The introduction of the AL-TEC, PVD coating chiefly for nodular cast iron, a-TECH, CVD coating mainly for grey cast iron and the DO-TECH, dual CVD PVD coating for refined strength will revolutionize the way manufacturers machines cast iron. Moreover, Iscar manufacturing mini inserts is another trend within the Upgrade movement, referring to decreasing the sizes of the Tangmill carbide inserts into Minitang, in order to facilitate fine pitch configuration which will expedite feed rates. In addition, the minimal size of the carbide inserts and their tangential orientation in the pockets allow a much greater core diameter, in terms of tool design, when compared to typical radially positioned inserts.
