Helical Solutions Inc. will exhibit its four newest cutting tools: the H40ALV and H40ALV-RN for cutting aluminum, the HSF-7 for finishing steel and exotic materials, the HEVR-5 family of tools for roughing and finishing steel and exotic materials, and the HXF for finishing steel and titanium.
The new H40ALV line includes a variable-pitch flute configuration and cutting diameter tolerances that are among the tightest in the industry (-0.0001 to -0.0004). This precision delivers reduced chatter, fewer tool offset adjustments and optimum tool performance. The line also includes full corner radius ranging from 0.015-0.250 as standard. Contributing to improved finishes are the H40ALV’s wiper flats. Helical’s wiper design burnishes the part floor without creating too much tool pressure/friction.
The center-cutting HSF-7 features geometries specifically engineered to cut difficult-to-machine materials. Its seven-flute design allows for higher feed rates compared to conventional end mills, and its high-helix flute design allows for free cutting at higher speeds and feeds. The HSF-7 allows operators to experience 75 percent production increases over four-flute tools and a 40 percent production increase compared to five-fluted tools.
The HEVR-5 and the longer-reach, reduced-neck HEVR-RN-5 tools also feature corner radii for added strength and have a variable-pitch design for increased depth of cut, up to 1 times the diameter of the tool resulting in an increased metal removal rate along with minimizing any possibility of chatter. Additionally, and due to its unique design features, it is not uncommon for customers to utilize the HEVR-5 for both roughing and finishing, reducing the number of tools and setups.
The HXF and HXF-RN end mill series feature corner radii for added strength and high-helix angles for smoother cutting and a better finish. The tools are designed for small radial depths of up to 6 percent of cutter diameter and axial depths of cut up to 1 to 1.5 times cutter diameter. However, with the tool’s increased number of flutes, along with the proper use of “radian chip thinning techniques,” a customer will undoubtedly experience an increased metal removal rate and improved tool life.
