The new Eliminator series of end mills from Tewkesbury-based Quickgrind Ltd (
www.quickgrind.com) is purpose-designed to increase the metal removal rate (MRR) when performing five-axis machining operations.
These end mills incorporate a tapered form designed to achieve reductions in cycle time of up to 95%, thanks to their ability to reduce tool-path distances while using the entire flute length to increase the step-down rate and subsequent MRR.
Furthermore, the geometry of Eliminator reduces the potential for thermal deformation, dissipating heat from the cutting edges to extend tool life and improve surface finish.
From an application perspective, Eliminator tools are particularly suited to semi-finish and finish-machining processes on a range of components, including aerospace turbine blades.
The solid-carbide end mills are available uncoated or with Quickgrind’s Type D geometry and an MX coating for the machining of low- and medium-alloy steel, tool steel, cast iron and hardened steels.
Alternatively, Type S end mills are XRed-coated for the machining of high-temperature alloys such as Inconel,
Hastelloy and titanium, as well as stainless steels. Eliminator cutters can be used as a direct replacement for ball-nose cutters and standard end mills.
They are available as three- or four-flute cutters, which are offered in shank diameters of 6, 8, 10, 12 and 16mm; they taper down to a ball-nose diameter of 1, 2, 3 or 4mm.
