A new turning geometry for the finish turning of components manufactured from steel to the most difficult-to-machine materials, such as high-temperature alloys, has been launched by ATI Stellram. The Stellram 1B insert is available in a choice of hard- wearing grades comprising of SP0819, which is designed for high cutting speeds on difficult-to-machine materials, and Nitro-Lok coated NL37, designed for high cutting speeds in unalloyed and alloyed steels. These grade and coating technologies combined with this unique geometry, not only boost productivity but improve component integrity. 1B Geometry features a precisely controlled cutting edge and nose profile, designed so that material can be removed cleanly, and efficiently leaving a superior surface finish at varying depths of cut and feed rates. According to ATI Stellram, the 1B geometry has been designed in combination with proven grades and coatings to provide high resistance to heat and edge breakdown, resulting in little to no loss in tool life while still increasing productivity.

Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
