Iscar Offers A New Family Of Slitting Cutters Using Tang-Grip Technology And The Durability Of Sumo Tec Grades

Iscar currently offers a family of high-performance slitting tools that merge the convenience and security of Tang-Grip clamping with the increased sturdiness of the brand new Sumo Tec insert grades.

The idea, already proven effective 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 with a specialized hand tool, and are clutched tightly in place without having the need for clamps, upper jaws or set screws that can weaken the insert and block chip flow. The pocket design utilizes cutting forces to keep the insert seated firmly in position, eliminating any prospect of insert pull-out. The Tang-Grip clamping system also fosters increased accurate slitting cuts plus increased pocket and insert life.

Iscar's Sumo Tec insert grades feature a special post-coating treatment which extensively improves tool life and reliability.

Introduced in late 2007, the revolutionary Sumo Tec treatment smooths the insert's coated surface to eradicate microscopic stress raisers, decrease heat and friction and improve chip flow. The result is enhanced toughness and resistance to chipping and built-up edge, all leading to longer tool life. The golden-colored side on Sumo Tec inserts aides wear detection. Size for size, Tangslit cutters offer more teeth than Iscar's SGSF cutters, allowing higher feed rates.

Their higher rigidity leads to straighter, more accurate cuts and reduced 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 selection of inserts as Tang-Grip parting tools. Several other sizes will be added.

Existing Sumo Tec grades for Tangslit cutters include:
IC808, with a tough submicron substrate beneath a Sumo Tec TiAlN PVD coating, delivering superb 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, offering additional toughness for heavier parting and grooving including interrupted cuts. It is suited for any stainless steel and high temperature alloys.

IC908, a hard, fine-grain substrate with exceptional chipping resistance, combined with a brand new Sumo Tec TiAlN PVD coating. It is ideal for nodular or gray cast iron.

IC928 and 928A, PVD TiAlN-coated tough grades suitable for stainless steel, high temperature alloys and other alloy steels. These grades are additionally suggested for interrupted cuts and heavy operations.

Each Tangslit and Tang-Grip inserts are presented in J- or C-type chipformer geometries from Iscar.

A Variety Of Developments 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.

Iscar Recently Releases Numerous Revolutionary Lines To Enlarge Their Family Of Milling Tools
Iscar recently released a new family of High Speed Milling adjustable endmills and facemills that will improve milling of aluminum, non-metallics, cast iron and hardened steel. This should prove especially useful in the automotive and aerospace industries.

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.

Push Pull Testing For Building Industry Supplying Calibrated Gauges. Stress Load Testing Methods For On Site Evidence To Testing Requirements.
Push Pull Testing for the Railway industry for proof of reliable anchor fixings. Calibrated push pull force gauges are used for stress load testing along with tensile strength pull testing procedures. Proof of load testing undertaken, measured, recorded in a reliable and standard way to BS5080 Part 1 standards.

The Latest In Carbide Endmill Architectures In A Extensive And Prosperous Line 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.
