Under the theme "The Road to Success Starts Here," Sandvik Coromant will be showcasing a broad range of tools at IMTS 2010. With new solutions for an incredible variety of machining applications, the company will be located in booth #W-1500 at the trade show, which is held September 13 - 18 at McCormick Place in Chicago, Illinois.
To meet growing demand from the aerospace sector for reliable and efficient hole making technology in composite materials, cutting tool and tooling systems specialist, Sandvik Coromant launched its specially designed CoroDrill 854 and CoroDrill 856. These tools were developed to withstand the harsh demands of the latest CFRP materials and aluminum stacks, offering long and consistent tool life to meet tight tolerances. The geometrical shape of CoroDrill 854 is designed to improve hole entrance and hole exit quality on high fiber content materials. Correct selection is critical to successful composite hole making: CoroDrill 854 is preferred where splintering or fraying is the problem, while customers will find more benefit with CoroDrill 856 if delamination is proving to be the difficulty in resin-rich materials.
Sandvik Coromant insert grade GC1135 offers exceptional quality for threading operations in stainless steels, super alloys and profiles requiring sharp cutting edges, according to the company's press release. The grade is available in the 0.630" insert for CoroThread 266. This size insert is suitable for the majority of general threading applications and benefits from the iLock interface with its secure insert clamping. This stability improves the threading performance with greater precision and fewer passes.
CoroMill 490, the milling cutter that can shoulder mill, face mill, edge, contour, slice, slot, in all materials, can now take up to 0.393"depth of cut. The latest release in the CoroMill 490 family from Sandvik Coromant is a 0.551" insert designed for larger depths of cut and engagements up to 0.393". The new insert size is introduced in an extensive program of cutter bodies in diameter range 1.574" - 9.842" and in grades and geometries for steel and cast iron machining. This universal milling package creates low operating costs and magazine space saving, typically reducing machining costs by 25 percent.
Grades S30T and S40T are available for a variety of CoroMill cutters for face, shoulder, long-edge and high feed milling, plunging, profiling and slot milling. Grade S30T was developed with productive titanium milling in focus, combining the properties of micro-grain carbide and a wear resistant PVD coating. This enables very sharp cutting edges that resist fatigue and micro-chipping and results in cutting edges that are preserved for longer times in cut at higher cutting speeds. Grade S40T excels in difficult conditions, offering the high toughness of cemented carbide and a thin CVD coating. The result is a grade that withstands vibrations and other difficult cutting conditions for longer times in cut. The wear is predictable, making the cutting edge gradually duller without breaking.
A new range of integrated toolholders compatible with CoroMill 316 exchangeable-head (EH) tools achieves a more secure performance than cylindrical shanks clamped in a precision chuck, with comparable tool overhang, regarding torque transmission, run out and accuracy. When all machining variables are the same, integrated holders with an EH coupling also provide shorter total programming length and higher stability when compared to cylindrical shank tool holders. With modular tooling possibilities, the holders can be used in many tooling combinations to suit applications and machine tools using a smaller inventory of standard items. For greater tooling flexibility, these holders also reduce set-up times, require minimum adjustment of tool length for each application and guarantee stable performance.
In addition to these showcased products, Sandvik Coromant will also be revealing hundreds of other new additions to its assortment of cutting tool products, applicable to nearly every industry and type of application.
