The Kennametal APX series of ROCTEC nozzles provide 20 percent greater life than the industry-leading ROCTEC 500 waterjet series, which already significantly outperforms other conventional tungsten carbide nozzles. The APX nozzles are suitable for use in precision cutting applications where long, uninterrupted cuts or close tolerances must be maintained for long periods to maintain part integrity or minimize expensive scrap due to premature nozzle failure.
"We're always trying to push the boundaries of performance, and we heard from customers the need for even greater productivity—to make longer cuts, gain more flexibility, and produce better parts on their waterjet machines," says Jeff Gardner, key account manager at Kennametal. "At the same time, waterjet machine builders continue to develop higher pressure pumps and more efficient cutting processes. ROCTEC APX is a next-generation nozzle designed to meet these needs."
Using APX series nozzles, waterjet shops can take on even more challenging, complex jobs or run at faster production speeds or longer production periods. It also enables customers to better integrate technology advancements, including advances in waterjet pumps and cutting head technology. In addition, since APX nozzles are based on the original ROCTEC technology that has been the industry standard for over 20 years, they exhibit the predictable and consistent operating life for which Kennametal ROCTEC nozzles are known.
Intermetallic compound consisting of equal parts, by atomic weight, of tungsten and carbon. Sometimes tungsten carbide is used in reference to the cemented tungsten carbide material with cobalt added and/or with titanium carbide or tantalum carbide added. Thus, the tungsten carbide may be used to refer to pure tungsten carbide as well as co-bonded tungsten carbide, which may or may not contain added titanium carbide and/or tantalum carbide.
With approximately 25 percent longer tool life, the new KCSM30 milling grade from Kennametal directly reduces cost-per-part for shops working on titanium, according to the company.
With its new Beyond grade of fine-grain carbide and unique point geometry, the new HPS solid-carbide drill from Kennametal is reportedly achieving excellent metal-removal rates and long tool life, making it an ideal tool for holemaking in aluminum.
New Beyond MR (medium roughing) inserts from Kennametal a synergy of geometry and grade, with smooth cutting action and higher wear resistance among the results.
With eight cutting edges, the new KSSM8+ face milling platform from Kennametal is focused on maximum metal-cutting performance in cast irons and steel workpieces at a low cost.
By combining high clamping force and optimized interference levels, Kennametal says its new KM4X100 provides a robust connection, extremely high stiffness, and bending load capacity for greatly improved performance in machining high-strength alloys and other materials.
Advanced hard turning, or the use of superhard polycrystalline cubic boron nitride (PCBN) cutting tools for machining hardened ferrous materials like cast irons, is eagerly sought across a number of key manufacturing industries. Hundreds of millions of brakes discs, brake drums, flywheels, and…
Tool selection, tool configuration, and the best applicable tooling advice based on the customer's part and process requirements are all at the touch of a few mouse clicks in Kennametal's revolutionary NOVO.
Experienced manufacturers know that when milling, three main considerations predominate: metal removal rate, tool life, and surface finish. All three are critical to successful metalworking, but often one will predominate. Manufacturers facing parts requiring 90-degree shoulders also know that…
