Mitsubishi Materials Expands ARP Series for Aerospace & Power Sector

Mitsubishi Materials expands its ARP series of round insert, high runout accuracy milling tools, for machining difficult-to-cut materials with a high level of accuracy and efficiency. ARP is perfect for machining titanium, stainless steels, and other heat resistant alloys, that are used in the aerospace and power generation industries. A very precise insert seat pocket has been developed for significant gains in accuracy and strength. The ARP tool bodies also have two side faces with innovative insert geometry which has a special rake face that creates a uniform chip flow, guiding the cutting forces to the centre of the insert pocket.

A new grade and type of insert with 8 side seating faces have been added to the range. The traditional 4 side seating face inserts range has also been expanded. These new inserts have a wider core and thickness to help combat sudden fracturing under intense machining conditions. A new addition to the range is MP9140, a new PVD coated carbide grade, combined with a smooth top surface of the Al-rich AlTiN coating layer, and a special cemented carbide substrate. There is a total of four different high-performance grades, which can be paired with various chipbreakers.

The ARP series is offered with cutter bodies with shell types in diameters 40-100 mm. These bodies offer course, fine and superfine insert pitches with a choice of 4-11 inserts per tool depending upon the selected diameter. The company also includes a shank style tool which is available in standard and long lengths for the processing of hard to reach cavities for the machining of smaller surface areas and intricate forms. These standard and long reach tool bodies to meet a vast range of machining applications are offered in diameters 25, 32, 40, and 50 mm with 2-5 inserts. Moreover, versatile screw-in type tool bodies in 25, 32 and 40 diameters are also available.
