Iscar Releases An Innovative Line Of High Performance Carbide Grades For Heightened Productivity

A new family of Iscar turning inserts brings Sumo Tec performance and durability to CVD and DVD carbide grades. In identical tests in a variety of turning applications, the inserts out performed their immediate competitors by 26 to 288 percent. The key to the increased life is the Sumo Tec unique treatment, introduced in late 2007 in a restrained range of milling inserts, that perfects the coated surface and reduces surface tension stresses in insert coatings. These cause cooler running, superior chipping resistance, reduced built up edge and faithfully longer edge life in all workpiece metals. During the alumina coating process, internal tension stresses occasionally cause cracks. The completely new Sumo Tec treatment induces compression stresses, which aides to seal these cracks. The 7 revolutionary Sumo Tec turning grades consist of two for cast iron; 3 for steel and 1 for heat-resistant alloys and hardened steel. All the most predominant insert geometries are accessible from inventory, with new geometries being added frequently. Iscar also plans to add new grades additionally.

Here are the grades available:

FOR CAST IRON
IC5005, with a hard substrate, MTCVD TiCN and thick Al2O3 coating, is advocated 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 unusually high wear resistance is required.

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

FOR STEEL
IC8150, consisting of a incredibly hard substrate with a cobalt enriched outer layer, MTCVD TiCN and a thick alpha Al2O3 CVD coating. Promoting excellent 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 handle stainless steel and interrupted cuts in nodular cast iron.

IC8250, a tough substrate with the same outer layers. It features amazing thermal stability and protection to plastic deformation and is recommended for general machining of alloyed and stainless steel in a comprehensive range of conditions.

IC8350, featuring a very tough substrate under the same outer layers. It delivers superior shock protection and ample 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 proper for turning heat resistant alloys, austenitic stainless steel and hard steel at low to medium cutting speeds. In a test against its nearest competitor on all three materials, the elevation in tool life was up to 150%.

Key Test Results
Prior to releasing the new SUMO TEC turning tool family, ISCAR tested all grades against their closest opponent in a assortment of utilization's. Here are the crucial results for grades 5005 and 5010 in cast iron. The advancement was 47% in SAE 1045 steel and 250% in 4140. In forging steel, the completely new Sumo Tec insert lasted 2X as long.
