Able to face-groove virtually any diameter larger than 12 mm, the VHM series inserts have maximum groove depth of 40 mm. Available from Rouse-Arno, the inserts are available in two grades, the AK-40 and the AL-40. The AK-40 grade is constructed of solid micrograin carbide for machining aluminum, brass, copper, plastics and high-temperature alloys. The AL-40 grade is equipped with high-temperature coating for machining steel, stainless steel and cast steels.
Both grades feature through-coolant capability to cool the cutting edge and improve chip evacuation. With a ground design, the inserts are available in widths of 2, 2.5, 3 or 4 mm. Custom sizes are also offered.
Can Additive Manufacturing Increase Milling Feed Rates?
With PCD tooling, yes it can. The diamond cutting edges demand a large number flutes to realize their full effectiveness. Traditional methods for making cutter bodies limit the number of flutes, but 3D printing is delivering tools with higher flute density and other enhancements as well.
