Tungaloy adds a number of new geometries and shapes to its BXA20 line, a grade of coated T-CBN inserts, designed for efficiency for hard turning operations.

The BXA20 insert boasts a nano-multilayered PVD coating, which is twice as thick as conventional grades and coated on a dedicated PcBN substrate with enhanced toughness. This adds both wear and fracture resistance to the grade, designed for long and predictable tool life in continuous to interrupted cuts of hardened parts, the company says.

Twenty-two items are being added to this line, including inserts with wiper geometries and WavyJoint technology, to address a range of hard part turning needs.

BXA20 provides wear and fracture resistance in low to medium speed. Suited for a variety of applications from continuous to heavy interrupted cuts of hard part finishing as well as descaling of case-hardened steel, which often accompanies large and varying depths of cut.

WavyJoint brazing technology boosts productivity in large depths of cut and high feed rate conditions.

  • Swiss-Type Machines: More Than Just A Lathe

    CNC Swiss-Type machines have more capability built in than ever before. Many of these capabilites can be accessed using attachments that increase the throughput of the machine tool, improve the quality of the work coming off the machine and reduce or eliminate the need for secondary operations even for very complex workpieces.
