Solutions for hard turning with new PCBN grades
Seco Tools has expanded its family of PCBN insert grades to cover the entire spectrum of hard part turning applications. Using a new bimodal substrate and coating process, these new inserts extend tool life and increase productivity in a broader range of applications.
Seco’s PCBN grade chain for materials ranging f rom ISO H05 to H35 consists of CH0550, CBN060K, CH2540 and CH3515 and i s designed specifically for turning case hardened steels. They i ncorporate advanced coatings and a bimodal substrate with coarser grain materials, along with optimised cutting edge profiles for l ong and predictable machining performance.
CH0550 provides high speed continuous cuts in H 05 materials. CBN060K excel sin continuous to medium-interrupted cuts in H 15 materials. CH2540 offers strong performance in light-to-heavy interrupted cuts in H25 materials. CH3515 handles heavy interruptions in H 35 materials.
Each of Seco’ sPCBN grades is available in common ISO insert geometries in both metric and imperial specifications. Wiper geometry options are available to further enhance performance.
