Iscar Produces An Innovative Line Of Elevated Performance Carbide Grades For Heightened Efficiency
A original family of Iscar turning inserts brings Sumo Tec performance and strength to CVD and DVD carbide grades. In like tests in a variety of turning applications, the inserts outlasted their closest competitors by 26 to 288 percent. The key to the lengthened life is the Sumo Tec specialized treatment, introduced in late '07 in a limited range of milling inserts, that flattens the coated surface and diminishes surface tension stresses in insert coatings. These result cooler running, greater chipping resistance, lowered built up edge and reliably longer edge life in all workpiece materials. During the alumina coating procedure, internal tension stresses at times cause cracks. The completely new Sumo Tec treatment produces compression stresses, which aides to seal these cracks. The 7 completely new Sumo Tec turning grades incorporate 2 for cast iron; 3 for steel and 1 for heat-resistant alloys & hardened steel. All the most preferred insert geometries are obtainable 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 endorsed 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 especially high wear resistance is essential.
IC5010, presenting a tough substrate, MTCVD TiCN and thick Al2O3 coating, targets grey cast iron. It is favored for interrupted cuts and unstable turning conditions in other metals.
FOR STEEL
IC8150, consisting of a very hard substrate with a cobalt enriched outer layer, MTCVD TiCN and a thick alpha Al2O3 CVD coating. Featuring amazing thermal stability and resistance to chipping, this grade is endorsed for high speed turning of steel subjugated to 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 exceptional thermal stability and resistance to plastic deformation and is advocated for general machining of alloyed and stainless steel in a wide range of conditions.
IC8350, featuring a very tough substrate under the same outer layers. It accomplishes remarkable shock protection and favorable 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 against its closest competitor on all three materials, the enhancement in tool life was up to 150%.
Key Test Results
Prior to releasing the new SUMO TEC turning tool line, ISCAR tested all grades opposite their nearest challengers in a variety of applications. Here are the crucial conclusions for grades 5005 and 5010 in cast iron. The advancement was 47% in SAE 1045 steel and 250% in 4140. In forging steel, the new Sumo Tec insert lasted 2X as long.
