Iscar Releases An High Tech Line Of High Performance Carbide Grades For Heightened Production
A brand new 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 outlasted their immediate competitors by 26 to 288 percent. The key to the lengthened life is the Sumo Tec distinctive treatment, introduced in late '07 in a constricted range of milling inserts, that flattens the coated surface and reduces surface tension stresses in insert coatings. These lead cooler running, enhanced chipping resistance, diminished built up edge and faithfully longer edge life in all workpiece materials. During the alumina coating process, internal tension stresses sometimes 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 contain 2 for cast iron; 3 for steel and one for heat-resistant alloys & hardened steel. All the most desired insert geometries are attainable from inventory, with new geometries being added constantly. 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 stable or slightly unstable conditions. This grade may be used in hard cast irons when exceptionally high wear resistance is necessary.
IC5010, featuring 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 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 under 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 outstanding thermal stableness and resistance to plastic deformation and is endorsed 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 superb shock opposition 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 opposite its nearest competitor on all three materials, the elevation in tool life was up to 150%.
Key Test Results
Prior to unveiling the new SUMO TEC turning tool family, ISCAR tested all grades opposite their nearest opposition in a diversity of functions. Here are the crucial 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 cutting edge Sumo Tec insert lasted 2X as long.
