Iwaki, September 2020 — Tungaloy has expanded its DoPent line of face milling cutters by adding new grades and large diameter cutters.
DoPent is a line of face milling cutters that allows productivity gains in all materials. The cutter incorporates pentagonal double-sided inserts with 10 effective cutting edges. The neutral geometry of the insert, PNxU0905GNEN-MJ, allows use with either the right- or left-hand cutter, simplifying the tool setup process. This makes DoPent an ideal solution for duplex milling applications where the workpiece is machined with two simultaneous spindles.
All DoPent inserts feature a large rake angle and strong insert body that are optimally designed to reduce cutting forces on the insert’s rake and flank side by up to 30% and axial cutting force by up to 50%, ensuring light cutting actions and machining stability.
New cutter diameter additions include 200 mm, 250 mm, and 315 mm to the existing metric range of 32 – 160 mm and 8″ and 10″ diameters to the current 2″- 6″ imperial range. These additions will improve efficiency with reduced number of cutter passes when machining large-sized components.
Three new grades have been added to the line: AH3225 is a PVD-coated grade for steel milling with superior wear resistance and good coating substrate adhesion for long and predictable tool life; AH8015 features nano-multilayer coating with high aluminum content which provides the coating surface with extreme hardness and resistance to wear, built-up edge, and edge chipping, making the grade perfect for milling ISO-H materials; and NS740 is an uncoated cermet grade for steel finishing applications with excellent ability to prevent built-up edge — a perfect grade where mirror-finish, high surface integrity is required.
These additions will further enhance DoPent’s capabilities in such applications as general engineering, die and mold, automotive, shipbuilding, heavy equipment, and power generation.
