5. 사용 설명서
- 안전한 작업물: 작업 중 움직이지 않도록 항상 작업물을 단단히 고정하세요.
- 시작 도구: Turn on the grinding or sanding tool, allowing it to reach full operating speed before making contact with the workpiece.
- 압력을 가하세요: Apply consistent, moderate pressure. Excessive pressure can lead to premature disc wear, heat buildup, and reduced performance.
- Maintain Angle: Hold the tool at an appropriate angle to the workpiece, typically between 15-30 degrees, for effective material removal and to prevent gouging.
- 움직임: Move the disc smoothly and continuously across the workpiece to ensure even abrasion and prevent localized heat buildup.
- 쿨다운: Allow the disc and workpiece to cool periodically, especially during prolonged use, to prevent overheating.
- 종료: When finished, lift the disc from the workpiece before turning off the tool.
6. 유지관리
- 저장: Store fiber discs in a dry, cool environment, away from direct sunlight and humidity, to maintain their integrity and performance.
- 점검: Regularly inspect discs for wear, glazing, or loading. Replace discs that show significant wear or damage.
- 청소: If a disc becomes loaded with material, it may be possible to clean it using a dressing stick or wire brush, if appropriate for the disc type and application. Always follow safety guidelines when cleaning.
7. 문제 해결
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| Poor material removal / Slow cutting | Disc is worn, glazed, or loaded; insufficient pressure; incorrect disc for application. | Replace disc; increase pressure slightly; ensure disc grit is appropriate for task. |
