Iscar Produces An High Tech Line Of High Performance Carbide Grades For Elevated Productivity

A cutting edge family of Iscar turning inserts brings Sumo Tec performance and durability to CVD and DVD carbide grades. In the same tests in a range of turning applications, the inserts out performed their closest competitors by 26 to 288 percent. The key to the increased life is the Sumo Tec distinctive treatment, introduced in late 2007 in a constricted range of milling inserts, that smooths the coated surface and decreases surface tension stresses in insert coatings. These result cooler running, enhanced chipping resistance, lowered built up edge and truly longer edge life in all workpiece materials. During the alumina coating procedure, internal tension stresses occasionally cause cracks. The completely new Sumo Tec treatment produces compression stresses, which helps to seal these cracks. The 7 revolutionary Sumo Tec turning grades include 2 for cast iron; three for steel and 1 for heat-resistant alloys & hardened steel. All the most favorite insert geometries are accessible from stock, with new geometries being added routinely. 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 advocated 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 especially high wear resistance is imperative.

IC5010, headlining a tough substrate, MTCVD TiCN and thick Al2O3 coating, targets grey cast iron. It is advocated for interrupted cuts and unstable turning conditions in other materials.

FOR STEEL
IC8150, consisting of a extremely hard substrate with a cobalt enriched outer layer, MTCVD TiCN and a thick alpha Al2O3 CVD coating. Featuring outstanding 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 manage stainless steel and interrupted cuts in nodular cast iron.

IC8250, a tough substrate with the same outer layers. It features remarkable thermal stableness and protection 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 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 suitable for turning heat resistant alloys, austenitic stainless steel and hard steel at low to medium cutting speeds. In a test against its nearest competitor on all three materials, the improvement in tool life was up to 150%.

Key Test Results
Prior to launching the new SUMO TEC turning tool line, ISCAR tested all grades against their closest opponent in a mixture of functions. 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.
