Helical Introduces New 2-Flute End Mill for Aluminum Applications
GORHAM, ME - Helical Solutions LLC is introducing a new, two-flute high-performance, non-serrated end mill for roughing in aluminum applications, and has improved the design of three existing rough and finish aluminum-cutting tools. Each of the previously available tools has been special-order products but now are standard and available from stock.
The all-new end mill is designated the H35AL-2R and features a two-flute, high-performance design that allows for heavier material removal rates in roughing and pocketing applications as its generous flute configuration allows more room for chips. Helical's H35AL-2R will maintain the company's reputation for producing one of the tightest cutting tolerances in the aluminum-cutting industry (-.0001/-.0004) and the result will be significantly reduced chatter, fewer programming errors and optimum tool performance. It also features enhanced strength with a 35-degree helix angle and a choice of two corner radii for each cutter size from 1/8 inch to 1 inch in diameter. The tool is available uncoated or with a ZrN (Zirconium Nitride) coating that provides improved lubricity for maximum chip evacuation and resistance to abrasion for extended tool life.
Crafted of certified premium sub-micron grain carbide, the H35AL-2R is ideal for roughing and slotting applications and is available in stub and regular lengths.
In testing with tool path optimizing software cutting 6061-T6 aluminum, a Helical Solutions end mill achieved 1,000 IPM, compared to the 300 IPM for aluminum cutting tool designs previously available in the marketplace. The test conditions were 1-inch depth of cut, ½-inch width of cut, 12,000 RPM and .0277-inch chip load per tooth. This 100-cubic-inch-per-minute metal removal rate was achieved with a mere 10 percent load on a 20 HP (14.9 kW) vertical machining center. Over time, putting less stress on the machine results in longer machine life and longer tool life.
"The H35AL-2R design and the other three aluminum end mill designs have been performing well in the real world for many years as special-order products," says Helical Solutions National Sales Manager Scott Thiehen. "Now, with the launch of the new H35AL series, these tools will be available immediately and at standard tool pricing."
Three other Helical aluminum end mills have received re-designs for improved strength and compliance with aerospace industry specifications, and now are available as standard. First is the H35AL-RN-R2, which is similar in design and function to the H35AL-2R. The difference is that this tool has a reduced neck diameter with a relatively short flute length, allowing for longer reach into deep pockets while maintaining maximum tool rigidity. Additionally, the tool now includes corner radii for corner strength.
For finishing applications, Helical revised the three-flute H35AL-3R with complete corner radii for improved strength. The H35AL-RN-3R, which also now has corner radii for improved strength, is the longer-reach version of the H35AL-3R.
All three of the updated Helical tools are available in shank diameters ranging from 1/8 in. to 1 inch, and are made from certified premium sub-micron grain carbide.
