Notes
If no relief shape or corner R0 relief groove is specified at the bottom of the inner diameter, a polishing relief may be added at our discretion.
Tip
Examples of finishes achieved through internal diameter grinding are shown below.
Buffing (SPBF) Available Sizes
The supported sizes for buffing are as follows.
Size
| Length (ℓ) | Weight (W) |
|---|---|
| 12≤ℓ≤100 | W≤2.5kg |
Notes
Due to processing characteristics, buffing may unintentionally affect surfaces adjacent to the specified buffed surface, which may alter their appearance.
