For Maximum Volume Removal. The ASR Alpha Turbo is the latest addition to the Hitachi mould tool range, it is able to achieve extraordinary feeds and metal removal rates in roughing applications, on new and old machines. 2 to 5 times increased efficiency compared to conventional radius cutters. 4 to 5 times increased efficiency in deep milling with an overhang of 3D or more, and 2 to 3 times for shallow milling at 3D or less. This enables faster production resulting in quicker turnaround of components.The cutters low cut structure enables increases in feed per tooth of up to 5 times. In cutting of steel a feed per tooth of 0.6 to 3.5mm is achievable and already being successfully used. Feed per tooth in cast iron is 0.8 to 4.0mm. This application gave a metal removal rate of 633cm3 ASR 63 with an overhang of 480mm (7.6xD), 1.2mm axial doc, 44mm radial doc with a feed rate of 12mtr per minute. Only 834rpm were needed, material spec was P20 (1.2311) Tool steel Hrc32. In other applications 1000cm3 removal rates were achieved with a larger diameter cutter. The Alpha Turbo is capable of cutting 60 to 80 kg of steel, which is equivalent weight of an adult, within 10 minutes.
