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.
Hitting the Coolant Sweet Spot
Toolholders with integrated cutting fluid delivery channels offer threaded, fixed-position nozzles that direct parallel streams of coolant to pre-defined positions at the top of the cutting tool.
