End mills for machining turbine and bladed components
- June 2, 2019
Emuge Corp. has introduced a new line of end mills featuring geometry designed specifically for the high performance machining of turbine and bladed components.
The new Emuge turbine end mills offer cycle time reductions and longer tool life in challenging forms and materials, including titanium, nickel alloys, aluminum alloys and more.
Complex shapes including wide sweeping radii and deep pocketed cavities present challenges for aerospace and turbine manufacturers. Mould applications include machining tire moulds and plastic injection moulds, among others.
The new turbine end mills have a stable design including on the tools featuring a tapered flute construction. The end mills feature PVD applied, highly hard and heat-resistant coatings, and a newly developed geometry that enables aluminum machining.
The line includes a wide range of taper ball tools that feature a sub-micro grain carbide substrate and an HA cylindrical shank. The 3°, 4°, 6° and 8° Taper ball tools have two and three flute designs, and the 17.5° has three flutes. Polished flutes in the 3°, 4°, 6° and 8° tools promote chip evacuation in aluminum alloys. Coating options for the taper ball tools include ALCR for additional tool life in titanium alloys, high temperature alloys, stainless steel and aluminum alloys, and TIALN for heat and abrasion resistance in a wide range of materials such as stainless steel, steel alloys, cast iron and other ferrous metals.
Taper torus end mills include 3°, 4°, 6° and 8° sizes featuring two highly polished flutes, sub-micro grain carbide, and have a torus "cupped" radius end design for maximum step over lengths. ALCR coating is standard, and TIALN coatings are available.
A Long 8° Taper Torus style also features a torus cupped radius. The cutting flutes are tapered for increased efficiency in a range of designs from 5 to 15 flutes. The long taper torus tools are TIALN coated for maximum tool life and include axial coolant through capability.
The line also includes a torus long length tool style which features variable flute spacing for low vibration milling. The tools are available in designs ranging from five to nine flutes and have a corner radii of 1.0 or 2.0 mm (0.04 or 0.08 in.) Torus long length end mills are TIALN coated for maximum tool life and include coolant through capability.
