A NEW family of ISCAR turning inserts brings SUMO TEC performance and durability to CVD and PVD carbide grades.
Key to the longer life is the SUMO TEC special treatment, introduced in last year in a limited range of milling inserts, that smoothes the coated surface and reduces surface tension stresses in insert coatings.
These lead to cooler running, better chipping resistance, reduced built up edge, and reliably longer edge life in all workpiece materials.
During the alumina coating process, internal tension stresses sometimes cause cracks. The new SUMO TEC treatment induces compression stresses, which help to seal those cracks.
The seven new SUMO TEC turning grades include two for cast iron; three for steel and one for heat-resistant alloys and hardened steel.
All the most popular insert geometries are available from stock, with new geometries being added regularly. ISCAR also plans to add new grades.
Grade availability
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 stable or slightly unstable conditions. This grade may be used in hard cast irons when exceptionally high wear resistance is required.
* IC5010, featuring a tough substrate, MTCVD TiCN and thick Al2O3 coating, targets grey cast iron. It is recommended 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. Featuring excellent 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 recommended 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 delivers excellent shock resistance and good wear resistance on alloyed and stainless steel.
For alloys, stainless 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.
