A versatile turning geometry for the finish turning of components manufactured from steel to the most difficult-to-machine materials, such as high-temperature alloys, is available from ATI Stellram.
The 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 geometry not only boost productivity, but improve component integrity, the company says.\
The insert geometry features a controlled cutting edge and nose profile designed so that material can be removed cleanly and efficiently, leaving a superior surface finish, according to the company, at varying depths of cut and feed rates.
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.
