Seco Tools has expanded its family of PCBN insert grades for hard part turning. Using a bimodal substrate and nanolaminate coating process, these inserts are designed to extend tool life and increase productivity for a range of applications.

Seco’s PCBN grade chain for materials ranging from ISO H05 to H35 consists of CH0550, CBN060K, CH2540 and CH3515 and is designed for turning hardened steels. The coatings, bimodal substrate with coarser grain materials, and cutting-edge profiles are designed for long and predictable performance.

CH0550 is designed for prolonged wear resistance in high-speed, continuous H05 cutting. CBN060K is said to excel in continuous to slight interrupted H15 cuts. CH2540 is designed for continuous and moderate interrupted cuts in H25. CH3515 is said to be tough for handling heavy interruptions in H35 operations.

Each of the insert grades is available in common ISO insert geometries in metric and imperial specifications, as well as high-feed wiper geometries.

  • Start With The Right Speeds And Feeds

    Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.

  • Drill And Bore With A Face Mill

    Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.

  • Taking The Fear Out Of Hard Turning

    To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
