For hardened steel machining applications with exceptional tool life,
the Tungaloy Corporation has now developed its new coated CBN, BXM20.
The new BXM20 offers excellent adhesion strength that enables it to deliver
outstanding surface finishes regardless of cutting conditions.
The BXM20 has excellent chipping resistance that ensures it delivers a stable
cutting performance. It has a composition that makes it suitable for heavy interrupted
operations and it complements the BXM10 inserts that have been designated as
the choice for continuous machining at high speeds. Whilst the BXM10 is specific
in its attributes for continuous high speed machining, the BXM20 is ideal for general
and continuous machining as well as interrupted cutting and the removal of carburized layers.
With a remarkable impact resistance, the BXM20 has a high rupture strength
and hardness. This makes the new grade suitable for continuous, light, medium
and heavy interrupted machining. The new BXM20 is available with two chipbreaker
designations, the HM & HF inserts. The HM is suited for deep machining
whilst
the HF is ideal for medium depth machining. The new BXM20 incorporates a new
wiper edge that eliminates chatter and guarantees stable cutting performance.
The new grade has a unique curved shape on the cutting edge and this shape reduces
form errors. This new wiper insert can perform at higher feed rates than inserts
with a normal cutting edge.
The new BXM20 is available with either two or three cutting edges and
a clearance angle of 5, 7 or 11 degrees and corner radii of 0.2, 0.4, 0.8 and 1.2mm.
It offers performance beyond the capabilities of competitor inserts with
exceptional tool life, productivity and cost reduction performance.
