Finishing touches

A new versatile turning geometry for the finish turning of components manufactured from steel to 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 hardwearing grades consisting 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. The grade and coating technologies combined with innovative tool geometry are claimed to not only boost productivity, but also improve component integrity.

The 1B geometry features a precisely controlled cutting edge and nose profile designed so that material can be removed cleanly and efficiently leaving an excellent 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.

The company has also produced a dedicated product brochure, which includes the complementary medium to roughing 4E geometry for difficult to machine materials. The brochure provides a range of useful information including cutting data and chip control charts.
The 1B geometry is the latest in a series of new products from ATI Stellram that includes the -48 milling geometry.
