Kennametal is introducing new high-performance HSS-E-PM (powder metal) Beyond taps for large-diameter tapping. Target applications for the new tools include some of the most essential wind turbine components such as hubs, rings, and gearbox housings.
With a highly wear-resistant powder metal substrate and proprietary top layers and coatings, the new Beyond HSS-E taps provide superior performance in tapping steel components such as gear rings and mainshafts; or for tapping cast-iron components such as hubs, housing, and gear boxes. The taps are available in sizes from M24 to M42.
Designed for both conventional non-rigid and CNC-synchronous tapping machines, precision h6 shanks enable use in either conventional tap holders with square drive or in precision round toolholders. Wind energy component suppliers will want to note an extra-long version is available to reach the longer overhangs common on these large components.
"Unlike other choices on the market, the addition of these large size taps with our KSEM Plus modular drilling program provide a complete solution to drill and finish the hole," says Marcelo Campos, Senior Global Product Manager, Tapping at Kennametal. "Where most other large-size taps are specials, we're providing a broad standard range of differentiated designs and coatings for increased speeds and better tool life across a wide spectrum of applications."
Cylindrical tool that cuts internal threads and has flutes to remove chips and carry tapping fluid to the point of cut. Normally used on a drill press or tapping machine but also may be operated manually. See tapping.
Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
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…
Romicron fine-boring systems from Kennametal allow users to dial in extremely close tolerances while the tool is mounted in the machine tool, saving time and easing training.
New Beyond KYS40-grade solid ceramic endmills from Kennameta are presenting orders-of-magnitude improvements in machining high-strength nickel-based alloys, roughing at cutting speeds up to 3,300 SFM (1000 m/min) with tool life two to three times longer than comparable solid-carbide tools.
These five new Stellram NL turning grades are specifically engineered to provide optimal performance in a given application and workpiece material resulting in increased metal removal rates, improved surface finishes and up to 30 percent longer tool life, according to the company.
For manufacturers facing complex or stringent machining or finishing issues, electrochemical machining (ECM) is a notable process by which material can be removed inµm increments, reaching areas unreachable by other methods. To support the ECM process, Kennametal Extrude Hone has designed an…
One of the most fundamental keys to running an efficient and cost-effective plant is having the right tool in the right place at the right time. While the cost of a milling or turning insert may range from a few dollars to significant investment, not having that tool available when needed can shut…
UltraFlex, a new portfolio of wear-resistant surface treatments from Kennametal, brings industry-leading wear performance to components with complex geometries in power generation, oil and gas, and many other industries.
The "Kennametal Innovations" app features interactive, cutting-edge animations and real-world demonstrations of Kennametal's productivity-enhancing technologies for machining and industrial processes.
The KSRM line of cutters is a new, multipurpose milling solution from Kennametal specifically engineered for titanium and stainless steel applications.
