Medium-to-heavy turning insert from TaeguTec boosts tool life; cuts tool loads

Available with a variety of insert grades, the new HB Chipbreaker is capable of machining a diverse range of materials that includes carbon steel, stainless and hardened steel, cast iron, aluminium, inconel and titanium. Under extensive testing, the HB Chipbreaker has continually been proven to improve tool life by over 40%, while reducing cutting loads by over 30%, when compared to competitor products. The new HB Chipbreaker Series has an optimal cutting range of from 1 to 8 mm depth of cut at feed rates up to 1 mm/rev. Machining in this range, the HB Chipbreaker can significantly improve tool life, productivity and surface finishes on a wide variety of materials and applications. The HB Chipbreaker introduces an innovative new cutter body design and insert geometry that offers steady and constant chip evacuation and prolonged tool life. The combination of the exclusive toolholder and insert drastically reduce the cutting load and improve surface finishes. Available in SNMX and CNMX designations, the new inserts can be applied to five new toolholder formats that provide the end user with a series of cutting angles and geometries for a multitude of applications. The new development's benefits are credited to a number of elements. First, the new double-sided semi-heavy HB Chipbreaker insert has an optimised chipbreaker geometry developed specifically for heavy machining. Second, TaeguTec has developed a unique contact seat with a large convex that improves contact, positioning and rigidity between the insert and the seat. The insert seat is exchangeable with ISO toolholders and has a three dimensional geometry that increases the clamping forces. Added to this stability, the Turn Rush introduces an innovative new clamping structure that incorporates a hook lever design. This design improves insert changeovers, while significantly increasing the clamping forces by clamping the insert in two directions.
