Kennametal’s Mill 1-10 tooling platform performs common machining applications such as face milling, shoulder milling, pocketing, slotting, interpolating and ramping for steels, aluminum and exotics, all with one common insert style. The tooling platform accomplishes this through the use of multifunctional cutter bodies and First Choice inserts, which consist of different grades and edge preps for various work materials but utilize the same cutting geometry and size.
Cutter bodies come in straight and helical flute styles. End mills are available with integral cylindrical shanks in three lengths, Weldon shanks or as a screw-on-style head. They also are available as a shell mill. Helical cutter bodies use the company’s load optimized insert spacing (LOIS) pattern to reduce cutting load variation.
The inserts are one size and are designed with six geometries. They feature a positive cutting rake for freer cutting and an integrated wiper facet for superior floor surfaces. Various nose radii (0.01" to 0.12") accommodate virtually all machining needs, the company says. Exclusive First Choice grades and edge prep take the guesswork out of which insert to use for a given application, whether machining titanium or austenitic stainless steel or roughing or finishing aluminum and other materials. Also available is the FR geometry (PCD) for machining aluminum.
The end mill bodies are available with straight flutes in sizes ranging from 0.50" to 1.25" and helical flutes in sizes ranging from 0.75" to 1.25". Straight-flute shell mills come in sizes ranging from 1.5" to 4", and helical-flute shell mills come in sizes ranging from 1.5" to 2".
Editor PickCan Additive Manufacturing Increase Milling Feed Rates?
With PCD tooling, yes it can. The diamond cutting edges demand a large number flutes to realize their full effectiveness. Traditional methods for making cutter bodies limit the number of flutes, but 3D printing is delivering tools with higher flute density and other enhancements as well.
