Why CBN & PCD Inserts
Factory-direct super-hard CBN inserts for hard turning and PCD inserts for aluminum and non-ferrous finishing
- CBN (cubic boron nitride) inserts for hard turning 45-65 HRC — replace grinding in many cases
- PCD (polycrystalline diamond) inserts for aluminum, copper, composites and non-ferrous high-speed finishing
- Multiple CBN grades: high CBN content for hardened steel, low content for cast iron
- PCD grades for roughing, finishing and ultra-fine surface requirements
- Standard and custom geometries; OEM support
- Application support for cutting parameters and grade selection
CBN vs PCD — Which One for Your Operation?
| Material | Best Tool | Why |
|---|---|---|
| Hardened steel 45-65 HRC | CBN | Thermal stability + hardness, replaces grinding |
| Cast iron | CBN / ceramic | Abrasion resistance at high cutting speeds |
| Aluminum & alloys | PCD | Extreme hardness, no built-up edge, long life |
| Composites / CFRP | PCD | Wear resistance against abrasive fibers |

FAQ
Questions Buyers Ask
What is the difference between CBN and PCD inserts?
CBN (cubic boron nitride) is second only to diamond in hardness and works best on hardened steels (45-65 HRC) and cast iron — it can replace grinding in hard turning. PCD (polycrystalline diamond) is the hardest cutting material and works best on aluminum, non-ferrous alloys and composites, delivering extremely long tool life at high speeds.
Can CBN inserts replace grinding?
In many hard turning applications (45-65 HRC), CBN inserts can achieve surface finishes and tolerances comparable to grinding, with higher productivity, lower setup cost and dry machining. Typical applications: bearing races, gear shafts, die and mold components.
What is your MOQ for CBN/PCD inserts?
Standard sizes start at MOQ 10 pcs; custom geometries per drawings. Contact us with your application details for grade selection and pricing.
