Figure: The new CoroMill® Plura HFS ISO S tool from Sandvik Coromant is ideal for machining titanium and nickel-based alloy aerospace components.
Sandvik Coromant, a specialist in cutting and tooling systems, will offer a range of end mills with a unique geometry and material for the milling of ISO S materials CoroMill® Plura HFS ISO S tools Ensuring reliable and productive machining of titanium and nickel-base alloy workpieces, with impressive performance in aero-engine and structural applications.
In response to the anticipated growth of aerospace business over the next few years, CoroMill Plura HFS products include two end mill series optimized for titanium alloys and a family of end mills optimized for nickel-based alloys.For chip evacuation and heat generation, titanium alloys Sandvik Coromant developed a carbide end mill for common chip removal conditions as well as an end mill with an internal coolant and a new intercooler (patent pending) To ensure the best chip and temperature control.
Made of GC1745, a titanium alloy endmill with a solid, fine-grained (sub-micron) sintered cemented carbide body with a sharp and controlled cutting edge to withstand the harshest milling conditions, the new silicon- The layer has excellent wear resistance and low thermal conductivity. The tool is a 6-tooth product with an end edge over the center and an unequal pitch design. In addition, the core size is optimized for higher rigidity in titanium alloys processing The tip arc radius, rake angle and relief angle are all designed for the machining of these demanding materials.
The nickel-base alloy end mills are made of GC1710 and also have sharp and controlled cutting edges. The hard-wearing, fine-grained base is optimized for use in machining hard-point, high-viscosity, work hardening materials Treated Inconel 718. Here, a new coating made using the innovative HIPIMS (High Power Magnetron Sputtering) technique also has the property of reducing surface sticking and avoiding the formation of BUE (built-up edge) And extend tool life.
Tiziana Pro, Global Product Manager for Sandvik Coromant Carbide End Mills, said: "The new tool is designed to ensure high axial (ap) and small radial depth of cut (ae) and controllable maximum chip thickness For side milling, which effectively controls the cutting forces and achieves smooth cutting. Higher productivity results in higher throughput while longer tool life and increased reliability reduce the reject rates for high-value parts. Further benefits to customers Including reducing the cost of a single part of a tool and increasing the level of safety. '
The target aerospace components include titanium alloy wing and pylon parts, as well as engine housings made of Inconel 718. Applications in the oil and gas, medical and motor sport sectors, where titanium and nickel alloys are becoming more common Will benefit from it.
In order to highlight the potential benefits that we can offer, we piloted a trial of an LPT (Low Pressure Turbine) receiver made of aged Waspidoy 420 nickel base alloy with a horizontal machining center to increase the axial depth of cut and to reduce Small radial depth of cut (we know that larger radial forces cause deflection problems.) Comparing 12 mm diameter CoroMill® Plura HFS end mills to competing tools of the same size results in significantly higher metal removal rates, higher productivity Increase up to 198%.
