Tungaloy Expands DoTwistBall Series with New Shell Mill Diameters
DoTwistBall is designed to provide reliability during complex 3D milling processes.
Tungaloy has expanded its DoTwistBall line of copy milling cutters to include additional shell mill diameters. DoTwistBall is designed to provide reliability during complex 3D milling processes. The insert features a helically twisted structure, which fits the cutter seat constructed in a matching helical profile. This design provides secure insert positioning and installation with anti-twist protection during machining, the company says. In addition, the thick design of the insert helps to withstand machining impact, preventing insert fracture.
The cutter body can accommodate either round LNMX-MJ inserts with 4.0-, 5.0-, or 6.0-mm nose radii or LNMX-HJ inserts for high-feed milling, making the cutter potentially effective for machining complex curved surfaces typical in the die/mold industry. The new cutter diameters include 42, 52 and 63 mm in popular shell mill bodies to accommodate the LNMX04 inserts.
