Tungaloy Corp. is launching the BXA20 series, a new coated PCBN grade for machining hardened steel. BXA20 delivers predictable and long tool life in a range of applications from roughing to finishing, including descaling of case hardened steel, which usually requires a large stock to be removed. This PCBN 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 multilayered 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.

    Tangential velocity on the surface of the tool or workpiece at the cutting interface. The formula for cutting speed (sfm) is tool diameter 5 0.26 5 spindle speed (rpm). The formula…
  • depth of cut
    Distance between the bottom of the cut and the uncut surface of the workpiece, measured in a direction at right angles to the machined surface of the workpiece.
  • chipbreaker
    Groove or other tool geometry that breaks chips into small fragments as they come off the workpiece. Designed to prevent chips from becoming so long that they are difficult to cont…
