Why Hardened Steel Machining Needs CNC Cutting Tools

Cutting tools for hardened steel (45-65 HRC) — CBN inserts that replace grinding in many hard turning operations, plus tough carbide grades for lighter interrupted cuts.

  • CBN inserts for hard turning 45-65 HRC — replace grinding in many cases
  • High CBN-content grades for continuous hardened steel turning
  • Low CBN-content grades for cast iron and interrupted cuts
  • Negative geometries and rigid clamping for vibration-free hard turning
  • Surface finishes comparable to grinding with dry machining
  • Application engineering for speeds, feeds and depth of cut

FAQ

Questions Buyers Ask

Can CBN inserts really replace grinding?

In many cases yes — hard turning with CBN achieves Ra 0.4-0.8 finishes and tight tolerances with higher productivity, lower setup cost and no coolant. Typical parts: bearing races, gear shafts, die components. The machine must be rigid and vibration-free.

What speed should I use for CBN hard turning?

CBN performs best at high cutting speeds (typically 120-250 m/min for hardened steel). Below that, conventional carbide may be more economical. We provide recommended parameters with every CBN order.
