Consider the application and tool together
Bearing manufacture combines cutting with grinding, superfinishing and dressing. This overview complements the detailed bearing brochure with the documented PCBN application in bearing steel. Bearing type and machined surface determine the appropriate tool family.
This edited overview provides an introduction to the tool family. Complete original tables and illustrations remain accessible through the source links. You can move from the described operation directly to a technical discussion of your application.
Applications and tool assignment
| Application or feature | Tool and assignment |
|---|---|
| Bearing-ring bore and raceway | Vitrified CBN grinding wheels |
| Raceway finishing | CBN honing stones for superfinishing |
| Grinding-wheel profile | Diamond dressers |
| Continuous cutting of bearing steel | EBC16S PCBN grade in the source example |
Tool features and benefits
EHWA describes removal performance, precision, surface quality and longer useful tool life for bearing tools. EBC16S is presented as a coated low-CBN-content PCBN grade for continuous cutting of SUJ2 and 100Cr6. The cutting examples remain separate from grinding and honing values so that the process assignment is clear.
Documented application example
| Feature | Example value |
|---|---|
| Material | SUJ2 |
| Cutting speed | 220 m/min |
| Feed | 0.15–0.22 mm/rev |
| Depth of cut ap | 0.10–0.20 mm |
| Cut / coolant | Continuous / wet |
Example 1 from the EBC16S data sheet, PDF page 1. These values belong to the illustrated application; they are not general settings for every bearing-steel operation.
From your application to a tooling solution
State bearing type, ring or rolling element, machined surface and heat-treatment condition. Drawing, hardness, tolerances and desired surface help selection between cutting and grinding processes. Comparisons assess working time and useful part count together with achieved quality.
Start with the information already available. An existing tool, a photo or a drawing is often a useful starting point. Also discuss your goal: replacing an existing design, improving surface quality or reducing tool changes and machining time. Comparisons record quality, time and useful output together; missing information can be added during the technical discussion.
