Question

Почему мягкие металлы нецелесообразно обрабатывать напильником с мелкой насечкой?​

Answer 1

Ответ:

Мягкие металлы не рекомендуют опиливать личными или бархатными напильниками, так как зубья их быстро забиваются стружкой и перестают резать.

Why is it impractical to use a file with fine teeth to work on soft metals?

When it comes to working with metals, different tools are used depending on the hardness and properties of the metal. Soft metals, such as lead, tin, and aluminum, have low hardness and are easily deformable. Using a file with fine teeth, like a file with a fine cut or rasp, is not practical for working on soft metals for several reasons:

1. Inefficiency: Soft metals are easily scratched and deformed, and using a file with fine teeth can cause excessive material removal and damage to the metal surface. The fine teeth of the file can dig into the metal, resulting in an uneven and rough finish.

2. Clogging: Soft metals have a tendency to stick to the file teeth, causing clogging. This can reduce the effectiveness of the file and make it difficult to achieve a smooth and accurate finish. The metal particles can also become embedded in the file teeth, further reducing its efficiency.

3. Limited control: Soft metals are malleable and can easily conform to the shape of the file teeth. This can make it challenging to achieve precise shaping or remove material in a controlled manner. The fine teeth of the file may not provide enough grip or control over the metal, leading to unpredictable results.

4. Alternative tools: For working on soft metals, it is more practical to use tools specifically designed for these materials. For example, sandpaper, emery cloth, or abrasive pads can be used to achieve a smoother finish without excessive material removal. These tools allow for better control and a more even surface.

In summary, using a file with fine teeth to work on soft metals is impractical due to inefficiency, clogging, limited control, and the availability of alternative tools better suited for these materials.
