Iwaki, December 2021 — Tungaloy has introduced eight new CBN inserts with HP chipbreaker for its MiniForce-Turn turning insert family of double-sided positive geometry.
The MiniForce-Turn series offers innovative double-sided turning inserts with positive rake cutting edges on both sides. These proven inserts are capable of soft cutting action similar to that of positive inserts with an added advantage of double cutting edges.
New MiniForce-Turn CBN inserts feature HP chipbreaker and use unique WavyJoint brazing technology for the CBN tips, providing enhanced insert reliability during hard turning.
HP chipbreaker demonstrates excellent chip control during hard turning at 0.2 mm (.008″) or smaller depths of cut. The chipbreaker is designed with a strategical distance between the cutting edge and chip redirector. This not only inhibits crater wear development on the rake face for maximum tool life but also helps lighten cutting forces during machining, eliminating chatter marks and part scraps for improved machining stability.
Two CBN insert grades are available for further empowerment of hard turning productivity: general-purpose BXA20 grade covers an extensive application range from continuous to interrupted cuts at low to medium cutting speeds; while BXA10 grade features good wear resistance in continuous cuts of hardened steel parts, demonstrating exceptional insert reliability and long tool life.
