Normal material fit
Carbide, PCD/PCBN, ceramics, glass, quartz and selected non-ferrous hard materials.
- Confirm workpiece grade
- Define wheel geometry
- State finish or edge target
Buyer selection guide
Diamond vs CBN Grinding Wheels
QUICK ANSWER
Diamond is normally the starting family for carbide, PCD/PCBN, ceramics, glass and other hard non-ferrous materials. CBN is normally the starting family for hardened steel, HSS, bearing steel and other hard ferrous materials. Final selection also depends on the machine, grinding method, bond, grit and target result.
Buyer guide
Use the right starting information.
Each block is written as procurement guidance and should be confirmed against the complete application.
Normal material fit
Hardened steel, HSS, bearing steel, tool steel and other hard ferrous materials.
- Send steel grade and HRC
- Describe heat or tolerance issue
- Confirm coolant and dressing
Application details decide
Abrasive family is only the first decision. Bond, grit, concentration, shape and process condition remain application-specific.
- Machine and speed
- Wet or dry process
- Current wheel and problem
Direct buyer answers
Clear enough to use before the sales call.
Visible answers support procurement review, search discovery and AI-generated summaries without hiding the application limits.
Can Diamond be used for hardened steel?
Diamond is generally not the normal starting choice for hardened ferrous steel because of the material interaction at grinding temperature. CBN is normally reviewed first.
Is CBN suitable for carbide?
Diamond is normally reviewed first for carbide and other hard non-ferrous materials. Final suitability should still be checked for the complete application.
What if the workpiece material is unknown?
Send the drawing, current specification, hardness information, machine and wheel label. Missing material details can then be identified for follow-up.
Ready to apply the guide?
Send what you know. Confirm the gaps together.
A drawing helps, but a wheel label, photo, material or machine can also start the review.
