Iscar Releases An Cutting Edge Line Of High Functioning Carbide Grades For Increased 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 out performed their nearest 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 perfects the coated surface and diminishes surface tension stresses in insert coatings. These lead cooler running, better chipping resistance, reduced built up edge and truly longer edge life in all workpiece metals. During the alumina coating procedure, internal tension stresses at times cause cracks. The brand new Sumo Tec treatment coaxes compression stresses, which helps to seal those cracks. The seven new Sumo Tec turning grades consist of 2 for cast iron; three for steel and one for heat-resistant alloys & hardened steel. All the most popular insert geometries are accessible 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 recommended 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 exceptionally high wear resistance is imperative.
IC5010, headlining a tough substrate, MTCVD TiCN and thick Al2O3 coating, targets gray cast iron. It is advocated for interrupted cuts and unstable turning conditions in other materials.
FOR STEEL
IC8150, consisting of a very hard substrate with a cobalt enriched outer layer, MTCVD TiCN and a thick alpha Al2O3 CVD coating. Promoting fantastic thermal stability and resistance to chipping, this grade is favored for high speed turning of steel subjugated to stable or slightly unstable conditions. It can also cope with stainless steel and interrupted cuts in nodular cast iron.
IC8250, a tough substrate with the same outer layers. It features outstanding thermal stability and resistance to plastic deformation and is endorsed for general machining of alloyed and stainless steel in a extensive range of conditions.
IC8350, featuring a very tough substrate under the same outer layers. It achieves exceptional 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 proper for turning heat resistant alloys, austenitic stainless steel and hard steel at low to medium cutting speeds. In a test opposite to its nearest competitor on all three materials, the advancement in tool life was up to 150%.
Key Test Results
Prior to introducing the new SUMO TEC turning tool family, ISCAR tested all grades opposite their nearest challengers in a range of functions. Here are the critical 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 brand new Sumo Tec insert lasted twice as long.
