Iscar Releases An Leading Edge Line Of Elevated Performance Carbide Grades For Elevated Production

A cutting edge family of Iscar turning inserts brings Sumo Tec performance and strength to CVD and DVD carbide grades. In the same tests in a range of turning applications, the inserts out performed their closest competitors by 26 to 288 percent. The key to the longer life is the Sumo Tec specialized treatment, introduced in late 2007 in a limited range of milling inserts, that smooths the coated surface and diminishes surface tension stresses in insert coatings. These result cooler running, greater chipping resistance, reduced built up edge and reliably longer edge life in all workpiece materials. During the alumina coating preparation, internal tension stresses occasionally cause cracks. The completely new Sumo Tec treatment leads to compression stresses, which aides to seal these cracks. The 7 revolutionary Sumo Tec turning grades consist of two for cast iron; three for steel and 1 for heat-resistant alloys and hardened steel. All the most popular insert geometries are offered from inventory, with new geometries being added routinely. Iscar also plans to add new grades likewise.

Here are the grades available:

FOR CAST IRON
IC5005, with a hard substrate, MTCVD TiCN and thick Al2O3 coating, is recommended mainly for nodular cast iron. It also handles other cast irons at medium to high cutting speeds at stable or slightly unstable conditions. This grade may be used in hard cast irons when especially high wear resistance is imperative.

IC5010, presenting a tough substrate, MTCVD TiCN and thick Al2O3 coating, targets grey cast iron. It is endorsed for interrupted cuts and unstable turning conditions in other metals.

FOR STEEL
IC8150, consisting of a exceptionally hard substrate with a cobalt enriched outer layer, MTCVD TiCN and a thick alpha Al2O3 CVD coating. Promoting outstanding thermal stability and resistance to chipping, this grade is recommended for high speed turning of steel under stable or slightly unstable conditions. It can also cope with stainless steel and interrupted cuts in nodular cast iron.

IC8250, a tough substrate with the same outer layers. It features excellent thermal stableness and protection to plastic deformation and is advocated for general machining of alloyed and stainless steel in a extended range of conditions.

IC8350, featuring a very tough substrate under the same outer layers. It delivers superior shock resistance and good wear resistance on alloyed and stainless steel.

For Alloys, Stainless Steel and Hardened Steel
IC807, with a tough submicron substrate under a TiAlN PVD coating, is fitting for turning heat resistant alloys, austenitic stainless steel and hard steel at low to medium cutting speeds. In a test opposite to its closest competitor on all three materials, the enhancement in tool life was up to 150%.

Key Test Results
Prior to introducing the new SUMO TEC turning tool family, ISCAR tested all grades against their nearest challengers in a range of operations. Here are the crucial conclusions for grades 5005 and 5010 in cast iron. The enhancement was 47% in SAE 1045 steel and 250% in 4140. In forging steel, the completely new Sumo Tec insert lasted 2X as long.
