The company has introduced a new line of premium, powdered metal roughing end mills for aluminum. The powdered metal substrate is said to provide the toughness of high speed steel and wear characteristics similar to micro-grain carbide for slotting, pocketing and peripheral milling of aluminum.
According to the company, the line is designed with geometry optimized for efficient machining of aluminum alloys. The line's chip-breaker design is said to reduce torque and horsepower requirements, and its high helix design allows for efficient evacuation of chips. Heavy axial and radial cuts can be made at elevated speeds and feeds with the end mills.
The powdered metal end mills are offered in various cutting diameters (1/2" to 2"), shank diameters (1/2" to 2") and flute lengths (1 1/4" to 6"). They are available uncoated or with TiCN and ZrN coatings. The end mills can be used on light- to medium-duty CNCs, as well as on large gantry-type mills.
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.
