Rough milling geometry designed for
irons
A specific geometry for rough milling gives it a much stronger cutting edge than the existing fine and medium geometries for machining cast, SG and tempered irons.
The development of a specific geometry for rough milling has extended the range of inserts available for WNT's 2011 indexable insert milling system, with particular emphasis on machining cast, SG (spheroidal graphite) and tempered irons Available with a choice of coatings, Al2O3, TiN and WNT's HCN grade, the R50 geometry is also one of the first inserts from WNT to be released in the cast, SG, tempered iron specific CWX3215 carbide grade with Al2O3 coating

Cutters make light work of hard materials
Tool life when cutting hard materials up to 70 HRc is greatly improved, thanks to the development of a PVD-multilayer coating used on solid carbide milling cutters.
The design of the insert gives it a much stronger cutting edge than the existing fine and medium geometries, a feature, that is complemented by a series of standard corner radii, including 0.4mm, 0.8mm, 2.0mm and 2.5mm as standard.
Typical cutting data is 140-350m/min for grey cast iron, 100-250m/min for grey cast iron with spheroidal graphite and 120-320m/min for tempered iron.
"The R50 roughing geometry is a perfect addition to the 2011 range of inserts and cutter bodies," said Tony Pennington, WNT (UK) managing director.
"The initial concept of 2011 was to provide an alternative to the 15-20 year-old APKT milling insert technology and to create cutters that deliver extremely quiet machining with minimal vibration and, consequently, very low stress levels on the machine tool".
Pennington said: "Customers now have a choice when it comes to 90 degree corner milling with a complete range of geometries (-F50, -M50, -ALP for light alloys, and -R50) to cover all machining applications, combined with a choice of high-performance tool coatings for added productivity".
The extensive 2011 series of inserts and cutter bodies ensures that the widest variety of metal cutting applications can be undertaken, including trachoidal groove milling; peripheral milling; shoulder milling; face milling, ramping, slot milling along with axial and helical plunge.
