Iscar Develops An High Tech Line Of High Functioning Carbide Grades For Elevated Efficiency
A original family of Iscar turning inserts brings Sumo Tec performance and strength to CVD and DVD carbide grades. In identical tests in a variety of turning applications, the inserts outlasted their nearest competitors by 26 to 288 percent. The key to the increased life is the Sumo Tec distinctive treatment, introduced in late 2007 in a restrained range of milling inserts, that perfects the coated surface and decreases surface tension stresses in insert coatings. These lead cooler running, better chipping resistance, decreased built up edge and reliably longer edge life in all workpiece metals. During the alumina coating preparation, internal tension stresses at times cause cracks. The completely new Sumo Tec treatment produces compression stresses, which assists to seal those cracks. The seven brand new Sumo Tec turning grades include 2 for cast iron; 3 for steel and 1 for heat-resistant alloys & hardened steel. All the most desired insert geometries are obtainable from stock, with new geometries being added regularly. Iscar also plans to add new grades as well.
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 stationary or slightly unstable conditions. This grade may be used in hard cast irons when unusually high wear resistance is necessary.
IC5010, presenting a tough substrate, MTCVD TiCN and thick Al2O3 coating, targets gray 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. Featuring superior thermal stability and resistance to chipping, this grade is suggested for high speed turning of steel subsequent to stable or slightly unstable conditions. It can also manage stainless steel and interrupted cuts in nodular cast iron.
IC8250, a tough substrate with the same outer layers. It features exceptional thermal stableness and resistance to plastic deformation and is recommended 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 opposition and excellent 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 improvement in tool life was up to 150%.
Key Test Results
Prior to launching the new SUMO TEC turning tool line, ISCAR tested all grades against their closest opposition in a mixture of utilization's. Here are the principal conclusions for grades 5005 and 5010 in cast iron. The improvement was 47% in SAE 1045 steel and 250% in 4140. In forging steel, the new Sumo Tec insert lasted twice as long.
