Rotary files are widely used in shipbuilding, repair, and maintenance. Here are some specific application scenarios:

1. Hull repair: When the hull is damaged, rotary files can be used to grind the damaged area, remove rust and old paint, and prepare for welding or repair work.

2. Hull cleaning: Regular use of rotary files can remove marine organisms, algae, and other attachments on the hull, keep the hull clean, and the performance of the ship.

3. Welding preparation: Before welding, rotary files can be used to grind the welding area to ensure the cleanliness and flatness of the welding surface and improve the welding quality.

4. Deburring: Newly manufactured or processed hull parts may have burrs, and rotary files can effectively remove these burrs to ensure the smoothness and safety of the parts.

5. Cabin interior treatment: Wooden or plastic decorative parts inside the cabin may be worn or damaged during use, and rotary files can be used for grinding and trimming.

6. Engine maintenance: The engine and mechanical parts of the ship need regular maintenance, and rotary files can be used to clean and grind these parts to extend their service life.

7. Maintenance of propellers and rudders: Propellers and rudders may be damaged or deformed during use, and rotary files can be used to grind and trim them to restore their performance.

8. Detail repair: For the repair of ship details, such as side, deck, anchor, etc., rotary files can provide fine grinding and trimming.

9. Custom component production: In the process of making custom-ship components, rotary files can be used to finely grind and shape the components.

When using rotary files, the appropriate grinding head and speed should be selected to suit different materials and work requirements. At the same time, for safety reasons, appropriate protective equipment should be worn, such as safety glasses, dust masks, and gloves. When working on a ship, relevant safety regulations and operating standards should also be followed.
