ATI Stellram offers a versatile geometry for finish turning components ranging from steel to high-temperature alloys. The Stellram 1B insert is available in two grades: SP0819, which is designed for high cutting speeds in difficult-to-machine materials, and Nitro-Lok-coated NL37, which is designed for high cutting speeds in unalloyed and alloyed steels. These grade and coating technologies, combined with a unique geometry, are said to increase productivity.
The insert features a controlled cutting edge and nose profile, designed to remove material for a quality surface finish at various depths of cut and feed rates, the company says. Also, the geometry is said to provide high resistance to heat and edge breakdown.
Can 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.
