BXA20 – New coated CBN grade for hardened steel
BXA20 from Tungaloy delivers predictable and long tool life in a wide range of applications from roughing to finishing, including de-scaling of case-hardened steel, which usually requires a large stock to be removed. This innovative CBN grade exhibits excellent wear and fracture resistance in a low to medium cutting speed range, with enhanced tool life in continuous as well as interrupted cuts.
The BXA20 series is available with a built-in wiper for a superb surface finish at high feed rates or a chipbreaker for smooth chip control in large stock removal, covering a wide variety of applications.
Main features:
BXA20’s multi-layered PVD coating is twice as thick as the conventional grade to improve wear resistance. The top-most layer of the coating has a very low coefficient of friction to help reduce crater wear. This multi-layered PVD coating with enhanced adhesion strength increases chipping and peel-off resistances, thus assuring stable and long tool life.
The dedicated carbide substrate withstands a heavy load of interrupted cutting and large depth-of-cut machining.
With a bright silver finish, used corners can easily be identified
