PCBN Insert Grades Cover a Spectrum of Hard Part Turning
Seco Tools’ PCBN insert grades cover a spectrum of hard part turning applications and extend tool life and increase productivity in a broader range of applications by using a bimodal substrate and nanolaminate coating process.
Seco Tools’ PCBN insert grades cover a spectrum of hard part turning applications. Using a bimodal substrate and nanolaminate coating process, these inserts extend tool life and increase productivity in a broader 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 specifically for turning hardened steels. They incorporate advanced coatings and a bimodal substrate with coarser grain materials, along with optimized cutting edge profiles for long and predictable machining performance.
CH0550 provides prolonged wear resistance in high-speed continuous cut H05 operations, CBN060K has continuous to slight interrupted cuts in H15 applications, CH2540 offers continuous and moderate interrupted cuts in the H25 area, and CH3515 exhibits toughness handling heavy interruptions in H35 operations. Each grade is available in common ISO insert geometries in both metric and imperial specifications. High-feed wiper geometry options are available to further enhance performance.
Producing a keyway, spline or similar longitudinal feature on a turned part usually necessitates an additional, time-consuming, secondary operation on a broaching or slotting machine. That means moving the part to and from a secondary operation, an extra setup, additional labor and hourly machine costs and all of the other headaches that go with secondary operations.
Few materials have had a greater impact on our economy and industrialized culture than cemented tungsten carbide.
Sometimes a shop doesn’t do enough turning work to justify the purchase of a CNC lathe. But when it needs to produce precision turned parts, even if for a very small lot size, the shop needs a solution.
