Material and hardness
Send the steel grade and HRC when available; “hardened steel” alone may be too broad.
Application guide for hardened ferrous materials
CBN Grinding Wheels for Hardened Steel & HSS
DIRECT ANSWER
CBN grinding wheels are normally the starting family for hardened ferrous materials such as HSS, bearing steel and tool steel. Material grade and hardness, grinding method, heat control, wheel geometry, coolant and tolerance target should be reviewed together.

Selection inputs
Close the application gaps before choosing a specification.
These checkpoints support a useful RFQ; they are not a generic performance guarantee.
Heat and finish
Describe burning, discoloration, finish or tolerance instability as separate review targets.
Dressing and coolant
Dressing method, coolant delivery, speed and contact condition can materially affect the result.
Application RFQ checklist
Send what is available. Confirm what is missing.
A complete specification is not required for the first review. The items below help reduce follow-up and quotation ambiguity.
Use this checklist in my RFQ- Workpiece
- Steel grade, hardness, part type and grinding allowance
- Wheel
- Shape, dimensions, current bond, grit and maximum speed
- Process
- Machine, speed, feed, wet/dry condition and dressing
- Current issue
- Burning, loading, wear, finish, cycle or tolerance problem
- Commercial
- Quantity, delivery target, destination and packing
Application questions
Direct answers for technical buyers.
Visible answers summarize the normal starting route and the information needed for a useful review.
When should I start with CBN instead of Diamond?
CBN is normally reviewed for hardened ferrous materials. Diamond is normally reviewed for carbide, ceramics, glass and other non-ferrous hard materials.
Can CBN alone eliminate grinding burn?
Not necessarily. Burning can also involve bond, grit, wheel speed, feed, coolant, dressing and machine condition, so the full process should be reviewed.
What hardness information is useful?
Steel grade and HRC are useful when available. If they are unknown, send the part drawing, heat-treatment specification or current process information.
Need an application review?
Send the current wheel or grinding problem.
Start with the material, machine, drawing, label or result that needs to improve.
