Iscar Develops An Cutting Edge Line Of Elevated Performance Carbide Grades For Elevated Productivity
A original family of Iscar turning inserts brings Sumo Tec performance and strength to CVD and DVD carbide grades. In like tests in a range of turning applications, the inserts out performed their immediate competitors by 26 to 288 percent. The key to the lengthened life is the Sumo Tec special treatment, introduced in late 2007 in a constricted range of milling inserts, that smooths the coated surface and reduces surface tension stresses in insert coatings. These lead cooler running, superior chipping resistance, lowered built up edge and faithfully longer edge life in all workpiece metals. During the alumina coating procedure, internal tension stresses sometimes cause cracks. The new Sumo Tec treatment coaxes compression stresses, which aides to seal those cracks. The seven revolutionary Sumo Tec turning grades include two for cast iron; three for steel and one for heat-resistant alloys and hardened steel. All the most predominant insert geometries are attainable from inventory, with new geometries being added frequently. 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 dense 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 required.
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 materials.
FOR STEEL
IC8150, consisting of a extraordinarily hard substrate with a cobalt enriched outer layer, MTCVD TiCN and a thick alpha Al2O3 CVD coating. Promoting exceptional thermal stability and resistance to chipping, this grade is recommended for high speed turning of steel subjugated to stable or slightly unstable conditions. It can also deal with stainless steel and interrupted cuts in nodular cast iron.
IC8250, a tough substrate with the same outer layers. It features fantastic thermal stableness 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 achieves superb shock resistance 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 proper 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 elevation in tool life was up to 150%.
Key Test Results
Prior to introducing the new SUMO TEC turning tool line, ISCAR tested all grades against their nearest opposition in a range of utilization's. Here are the principal conclusions for grades 5005 and 5010 in cast iron. The betterment was 47% in SAE 1045 steel and 250% in 4140. In forging steel, the brand new Sumo Tec insert lasted 2X as long.
