Electroplated CBN and diamond JG mounted points for jig grinding, precision internal grinding and localized machining of small bores. Abrasive type, head dimensions, shank and grit are matched to the workpiece and machine conditions.
Small-Diameter Tools for Jig and Internal Grinding
- Electroplated CBN or diamond (SDC) abrasive
- Long-shank JG mounted-point format for restricted access
- Custom head diameter, abrasive length, shank and overall length
- Drawing- and application-based specification review
Select CBN or Diamond by Workpiece Material
| Abrasive | Typical Workpiece Materials | Typical Use |
|---|---|---|
| CBN | Hardened steel, bearing steel, high-speed steel and suitable ferrous alloys | Small bores, internal profiles and localized grinding in hardened ferrous parts |
| Diamond / SDC | Cemented carbide, technical ceramics and other suitable hard, brittle non-ferrous materials | Precision internal and localized grinding where diamond is compatible with the workpiece |
Important: CBN and diamond are not interchangeable. The workpiece material, hardness and grinding conditions must be confirmed before quotation.
Typical Applications
Jig Grinding
Precision finishing of small bores and localized internal features on coordinate or jig grinding equipment.
Internal Profiles
Grinding of cylindrical holes, shoulders, recesses and other internal details where access and tool clearance are limited.
Drawing-Based Special Tools
Non-standard head and shank dimensions developed from the workpiece drawing, spindle interface and required finish.
Specification Guide
| Abrasive | CBN or diamond (SDC), selected by workpiece material |
| Construction | Electroplated superabrasive layer on a precision mounted-point body |
| Head geometry | Cylindrical JG format; special profiles by drawing review |
| Dimensions | Head diameter, abrasive length, shank diameter and overall length to be confirmed |
| Grit | Selected for stock removal, finish and workpiece material |
| Machine and spindle | Jig/coordinate grinder or compatible internal-grinding spindle; interface and speed range required |
| Speed and tolerance | Not assumed; confirm in the approved specification before use |
What to Send for Quotation
- Workpiece drawing, material grade and hardness
- Required head diameter, abrasive length, shank diameter and overall length
- Machine model, spindle interface and available speed range
- Stock allowance, dimensional tolerance and surface-finish target
- Coolant condition, current tool specification and order quantity
Process distinction: this product is a mounted grinding point for jig and internal grinding. It is not a honing mandrel or honing stone.
