| Tool | Rubber grindstone in the rotating tool |
|---|---|
| Problem | Finish quality varied from the skill of workers. It took around 40 minutes to deburr 16 holes (150 seconds/hole). |
| Tool | XEBEC Stone Flexible Shaft Type (CH-PM-6B) |
|---|---|
| Result | Insert the spherical grinding stone with the cross hole and contour the edge while pulling the tool lightly. Stable quality with shorter cycle time realized. |
