As a carbide insert manufacturer, OPT Cutting Tools produces PCD, CBN, and carbide turning inserts that span the full spectrum of modern turning applications. From high-gloss aluminum finishing to hard turning of 50-70 HRC hardened steel, the insert portfolio is engineered to match each insert grade and geometry to its ideal material, maximizing tool life and cost per part.
PCD Inserts for Non-Ferrous Turning
The TCGT PCD diamond lathe insert features a zero rake angle with a precision chip breaker groove, delivering exceptional wear resistance and surface quality in non-ferrous turning. For heavier cuts and high-gloss finishing, the CNGA PCD rhombic insert offers negative rake geometry that resists edge chipping under load while producing mirror finishes on aluminum and copper alloys.
CBN Inserts for Hard Turning
For hardened steel and cast iron, the CBN inserts TNGA enable hard turning up to 70 HRC as a direct alternative to grinding. CBN’s chemical stability with iron at high temperature means it cuts hardened ferrous materials that would instantly destroy PCD, delivering tight tolerances and excellent finishes in a single operation.
The Tool Life Advantage
- PCD inserts deliver 10-100 times the tool life of carbide in aluminum and non-ferrous applications.
- CBN inserts provide 5-50 times carbide life in hardened steel, replacing grinding with turning.
- Every insert undergoes 100% edge inspection with microscope-based verification before shipping.
By matching the right insert grade to the material, manufacturers unlock dramatic productivity gains. Factory-direct sourcing from OPT Cutting Tools brings these superabrasive advantages within reach, with comprehensive quality documentation and engineering support on every order.
