Seco to Spotlight Next-Generation Duratomic® Coating, New Cutting Tools for Modern Materials at AeroDef 2015

TROY, Mich., – At AeroDef 2015 in booth 313, Seco Tools, LLC will showcase its next-generation Duratomic coating technology that sets an all-new standard in turning performance. The company will also spotlight several new milling solutions and share applications expertise that bring advanced performance and high productivity to aerospace applications involving titanium, superalloy, aluminum, stainless steel and composite workpiece materials.

Next-Generation Duratomic Technology

In 2007, Seco set a new standard for insert wear resistance and edge toughness in turning applications with its Duratomic coating technology. It was the first time a company had manipulated a coating at the atomic level to achieve improved mechanical properties and thermal inertness that, in turn, allowed users to benefit from higher cutting speeds and fewer tool changes.

When compared to other grades on the market, Duratomic is still in a class of its own and a technology that Seco continues to improve. With the next-generation Duratomic technology, the company dives deeper into the world of atoms to establish a coating that will provide users with the ultimate edge in turning.

Highfeed 2 and 4 Milling Cutters

Seco’s family of Highfeed indexable-insert milling cutters allows users to machine up to three times faster than if they were to rely on conventional methods. The company recently expanded this lineup to include the new Highfeed 2 small-diameter cutter and Highfeed 4 cutter with double-sided inserts. Both cutters incorporate new insert designs combined with more teeth per diameter.

Highfeed 2 features LP05 single-sided inserts with two cutting edges for cutter bodies that range from 0.5" to 0.75" in diameter. Available in three different geometries, these positive LP inserts easily handle sticky materials such as stainless steels, titanium and super alloys. They are also a first choice for applications that require a higher ramping angle or superior plunging performance.

Highfeed 4 features LO06 double-sided inserts with four cutting edges for cutter bodies that range from 1.00" to 2.50" in diameter. Available in four different insert geometries, these close-pitch and negative-pocket LP inserts cost effectively machine common workpiece materials.

MS2050 Milling Grade

Seco has further expanded its MS2050 milling grade of inserts with new variations optimized for machining titanium and high-chromium-content steels. The grade features a new silver-colored PVD uni-coating that offers high heat resistance and eliminates built-up edge when cutting these sticky materials. With the absence of builtup edge, the inserts last approximately 50 percent longer and run at much higher cutting data as compared with existing inserts. Available in radii sizes that range from 0.016" to 0.25", these inserts come in positive geometries for shoulder, face, copy and high-feed applications and are applicable for use with the company’s Turbo 10, Helical T4-08 and Highfeed cutters.

Minimaster® Plus Replaceable Tip Milling System

Seco is continuously improving upon its Minimaster Plus replaceable tip milling system to make it even more adaptable for manufacturers. Most recently, the company added new through-tool coolant high-feed heads to the system. Available in .375", .500" and .625" insert diameters and corner radii ranging from 0.016" to 0.122", these latest highfeed heads easily machine steel, stainless steel, cast iron, aluminum and other challenging materials.

Jabro® JPD and JC End Mills

Seco recently added new JPD and JC end mills to its line of Jabro products developed specifically for composite materials. In fact, these cutting solutions incorporate special features that result in perfectly cut fibers and undamaged workpieces.

The JDP group of solid carbide end mills, which consists of the 880 square end mill, 850 ball nose end mill and 840 compression-type end mill, features brazed polycrystalline diamond plates to achieve fast, efficient cutting and long tool life. Main PCD-plated bodies include through-coolant channels for highly effective chip and dust evacuation. The JDP880 and JDP840 end mills are available in diameters that range from 0.24" to 0.63", while the JDP850 covers diameters from 0.16" to 0.63".

The JC group, which includes the 875 solid carbide router, delivers superior surface finishes via a special edge treatment that prevents wear and ensures the longest possible tool life. An added diamond coating further boosts the tool’s wear resistance, allowing it to withstand the highly abrasive properties of composite materials. Seco also imparted a special chip-splitting design to the end mill for clean cutting actions. Diameter ranges for the JC875 are from 0.12" to 0.47".

Niagara NS240R Long-Flute End Mill

Seco, through its Niagara brand of cutting tools, recently launched the NS240R solid carbide long-flute end mill for peripheral finish milling of aerospace parts requiring long axial engagement. The end mill comes with several advanced features, including a highly wear-resistant polished AlTiN coating for increased tool life, stabilized design for improved surface quality as well as an enlarged core diameter and impact defined back taper for increased stability and less tool deflection during machining. NS240R comes standard with a 5xD depth of cut and in diameters that range from 1/4" to 1 1/4" with various radii available, including aerospace radii.

Aerospace Applications Expertise

Seco applications experts will also be available at AeroDef to speak with manufacturers and share strategies for controlling chip flow and maximizing turning productivity, maintaining tight tolerances using complex machining strategies, increasing process security and hole quality, implementing complex machining strategies for high material removal rates and much more.
