Size expansion of the C-3SA, 3 flute ALIMASTER end mill

In recent years, with the expansion of the aerospace industry, there has been an increasing demand for high efficiency machining of aluminium alloy used for aerospace applications such as body and wing components. Additionally, there is also a growing demand from customers in the semiconductor industry for high performance deep slotting of aluminium alloy. To meet such demand, Mitsubishi Materials has supplied the ALIMASTER end mill series designed for high efficiency aluminium alloy machining.

The C-3SA is a range of the 3 flute ALIMASTER end mills (short cut length) that has enjoyed a good reputation for high efficiency machining of aluminium alloy due to the employment of the short cutting edge length and 37.5° helical flute geometry. To cover a wider range of machining applications, the C-3SA series is now supplemented with 7 different types of under cut type (1) that is suitable for deep slotting.
