Iscar Releases An High Tech Line Of Elevated Performance Carbide Grades For Increased Productivity
A new family of Iscar turning inserts brings Sumo Tec performance and stability to CVD and DVD carbide grades. In the same tests in a selection of turning applications, the inserts out performed their nearest competitors by 26 to 288 percent. The key to the increased life is the Sumo Tec specific treatment, introduced in late 2007 in a limited range of milling inserts, that perfects the coated surface and decreases surface tension stresses in insert coatings. These result cooler running, enhanced chipping resistance, reduced built up edge and faithfully longer edge life in all workpiece metals. During the alumina coating procedure, internal tension stresses sometimes cause cracks. The brand new Sumo Tec treatment leads to compression stresses, which helps to seal these cracks. The seven completely new Sumo Tec turning grades incorporate 2 for cast iron; three for steel and one for heat-resistant alloys and hardened steel. All the most favored insert geometries are obtainable from inventory, with new geometries being added routinely. Iscar also plans to add new grades additionally.
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 unusually high wear resistance is imperative.
IC5010, featuring a tough substrate, MTCVD TiCN and thick Al2O3 coating, targets gray cast iron. It is endorsed for interrupted cuts and unstable turning conditions in other metals.
FOR STEEL
IC8150, consisting of a extremely hard substrate with a cobalt enriched outer layer, MTCVD TiCN and a thick alpha Al2O3 CVD coating. Promoting extraordinary thermal stability and resistance to chipping, this grade is recommended for high speed turning of steel under 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 excellent thermal stability and resistance to plastic deformation and is favored for general machining of alloyed and stainless steel in a comprehensive range of conditions.
IC8350, featuring a very tough substrate under the same outer layers. It delivers excellent 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 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 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 opponent in a range of applications. Here are the principal 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 completely new Sumo Tec insert lasted 2X as long.
