Iscar Announces A Revolutionary Family Of Slitting Cutters Utilizing Tang-Grip Technology And The Durability Of Sumo Tec Grades
Iscar currently offers a family of high-performance slitting tools that incorporate the convenience and security of Tang-Grip clamping with the added durability of the completely new Sumo Tec insert grades.
The concept, already confirmed effective in Tang-Grip parting tools, has now been spread to slitting cutters. In the patented Tang-Grip clamping system, inserts are press-fit into their pockets accompanying a specialized hand tool, and are gripped securely in place without the need without requiring clamps, upper jaws or set screws that can weaken the insert and impede chip flow. The pocket design utilizes cutting forces to retain the insert seated tightly in position, eliminating any chance of insert pull-out. The Tang-Grip clamping system also fosters more accurate slitting cuts plus longer pocket and insert lifespan.
Iscar's Sumo Tec insert grades feature a specialized post-coating treatment which extensively increases tool life and constancy.
Introduced in late '07, the new Sumo Tec treatment smooths the insert's coated surface to dispose of microscopic stress raisers, reduce heat and friction and enhance chip flow. The result is enhanced toughness and opposition to chipping and built-up edge, all leading to enhanced tool life. The golden-colored flank on Sumo Tec inserts facilitates wear detection. Size for size, Tangslit cutters offer more teeth than Iscar's SGSF cutters, permitting higher feed rates.
Their greater rigidity leads to straighter, increased accurate cuts and reduced vibration even in large-diameter cutters. The revolutionary Tangslit TGSF cutters come in 100 to 160 mm diameters, 3 and 4 mm widths and can accept the exact same selection of inserts as Tang-Grip parting tools. Additional sizes will be added.
Available Sumo Tec grades for Tangslit cutters include:
IC808, with a tough submicron substrate beneath a Sumo Tec TiAlN PVD coating, providing excellent resistance to impact loads and built-up edge. This grade is recommended for slitting heat resistant alloys, austenitic stainless steel, hard alloys & carbon steel.
IC830, presenting increased toughness for heavier parting and grooving involving interrupted cuts. It is suitable for all stainless steel & high temperature alloys.
IC908, a hard, fine-grain substrate with excellent chipping resistance, combined with a completely 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 also recommended for interrupted cuts and heavy operations.
All Tangslit and Tang-Grip inserts are attainable in J- or C-type chipformer geometries from Iscar.
Cutting Edge Cutters And Carbide Insert Shapes From Iscar To Better Maximize The Machining Process
Iscar is introducing Penta 34 carbide inserts with a new PB chipformer. The PB chipformer features a single cavity with a positive rake, neutral shoulder angle, and a honed edge. It is actually a C-type chipformer with a different frontal edge.
The Latest In Carbide Endmill Designs In A Lengthy And Successful Family From Iscar
Manufacturers and die & mold shops can eliminate chatter problems in many milling operations with Iscar's new Chatterfree endmills. The cutters' variable-pitch flute pattern eliminates harmonic vibration, the main source of chatter. This enables faster cutting and finer finish in rough or finish slotting, shoulder milling and cavity milling.
Iscar Adds Their Latest Creations To A Long Line Of Outstanding Hole Generating Solutions
Iscar recently released several different drilling innovations to meet their customers needs. These new products are Sumocham Drill, DR-DH and Deep Drills. Drawing off of their experience Iscar has come up with new and innovative ways to increase productivity for the end user.
Some Improvements Have Enlarged Iscar's Line Of Indexable Endmills For Increased Productivity
Helido-Upfeed 04 Two years ago Iscar introduced the extremely efficient H600 indexable endmill line, based on conceptually new Helido-Upfeed double sided inserts with 6 cutting edges. The first insert launched was the H600 WXCU 0806..., which was designed for milling cutters in the diameter range of 50 to 125 mm.
A Handful Of Upgrades In Carbide Inserts Due To Iscar Over The Former Decade
Iscar is announcing a brand new unique milling system that includes tangential, clamped, butterfly-shaped LNKX carbide inserts. The butterfly-shaped insert has meaningful advantages compared to the current flat, square shapes. The new geometry has more cutting edges, positive rake face, decreased cutting forces resulting in better performance.
Revolutionary End Mills From Iscar Can Multiply Productivity While Reducing Costs
Manufacturers and die & mold shops can banish chatter problems in numerous milling operations with Iscar's new Chatterfree end mills. The cutters' variable-pitch flute pattern eliminates harmonic vibration, the primary source of chatter. This enables faster cutting and finer finish in rough or finish slotting, shoulder milling and cavity milling.
