Iscar Announces A New Family Of Slitting Cutters Utilizing Tang-Grip Technology And The Durability Of Sumo Tec Grades
Iscar now offers a family of high-performance slitting tools that combine the convenience and security of Tang-Grip clamping with the increased durability of the brand new Sumo Tec insert grades.
The conception, already established successful in Tang-Grip parting tools, has now been extended to slitting cutters. In the patented Tang-Grip clamping system, inserts are press-fit into their pockets accompanied by a special hand tool, and are clutched firmly in place without the need for clamps, upper jaws or set screws that can weaken the insert and thwart chip flow. The pocket composition utilizes cutting forces to keep the insert seated securely in position, preventing any risk of insert pull-out. The Tang-Grip clamping system also fosters more accurate slitting cuts plus lengthened pocket and insert life.
Iscar's Sumo Tec insert grades showcase a specialized post-coating treatment which substantially increases tool life and dependability.
Launched in late 2007, the revolutionary Sumo Tec treatment flattens the insert's coated surface to banish microscopic stress raisers, diminish heat and friction and improve chip flow. The result is enhanced toughness and opposition to chipping and built-up edge, all leading to greater tool life. The golden-colored side on Sumo Tec inserts eases wear detection. Size for size, Tangslit cutters give more teeth than Iscar's SGSF cutters, allowing higher feed rates.
Their superior rigidity leads to straighter, additional accurate cuts and diminished vibration even in large-diameter cutters. The new Tangslit TGSF cutters come in 100 to 160 mm diameters, 3 and 4 mm widths and can accommodate the exact same assortment of inserts as Tang-Grip parting tools. Additional sizes will be added.
Existing Sumo Tec grades for Tangslit cutters include:
IC808, with a tough submicron substrate below a Sumo Tec TiAlN PVD coating, giving exceptional resistance to impact loads and built-up edge. This grade is suggested for slitting heat resistant alloys, austenitic stainless steel, hard alloys & carbon steel.
IC830, presenting additional toughness for heavier parting and grooving including interrupted cuts. It is suitable for all stainless steel & high temperature alloys.
IC908, a hard, fine-grain substrate with extraordinary chipping resistance, combined with a brand new Sumo Tec TiAlN PVD coating. It is perfect for nodular or grey cast iron.
IC928 and 928A, PVD TiAlN-coated tough grades suitable for stainless steel, high temperature alloys and other alloy steels. These grades are likewise favored for interrupted cuts and heavy operations.
Every Tangslit and Tang-Grip inserts are presented in J- or C-type chipformer geometries from Iscar.
