The TungForce-Feed line of indexable, small diameter, high-feed milling cutters has been expanded by Tungaloy to include R2 inserts that feature a corner radius of 2 mm.
Available in diameters of 8, 10, 12 and 16 mm, the TungForce-Feed line is pitched as an economic profiling solution for the mould and die industry when compared with conventional solid end mills and indexable tools of similar size.
During the creation of a CAM program for the high-feed machining of complex 3D profiles in typical mould-making applications, it is common to use a theoretical corner radius for programming the insert radius. However, this method leaves excessive stock on the workpiece after machining, adding processes.
Looking to generate the ideal platform for subsequent finishing processes, many job shops are using solid-carbide square-end mills with large radii during roughing. The latest R2 insert requires no programming for the theoretical corner radius, as its 2 mm corner radius leaves no uncut material on the machined surface. This concept ensures that the TungForce-Feed series makes a good replacement for costly solid-carbide end mills.
Featuring an insert design that is 10% thicker than competitor products, the TungForce-Feed line is built to perform at higher machining parameters by withstanding fracture forces. The insert design incorporates a positive inclination angle for smooth chip evacuation which further reduces cutting forces by controlling chip formation, especially when shoulder and slot machining.
Designed for face and shoulder milling, as well as helical interpolation and ramping, the close insert pitch makes the TungForce-Feed line a good option for all milling applications. The series has been designed with a small entry angle for chatter stability that improves efficiency and tool life, even when machining in long-reach areas, says Tungaloy.
