Question

Почему напильников одно и тоже формы делается насечка разной глубины​

Answer 1

Ответ:

В зависимости от величины зуба, насечки и числа зубьев, приходящихся на 1 см длины напильника, насечкам присвоены соответствующие номера:

№ 1-драчевые напильники, у которых на 1 см длины приходится 5-13 зубьев (крупная насечка);

№ 2- личные напильники, у которых на 1 см длины приходится 13-25 зубьев (средняя насечка);

№ 3, 4, 5 и 6 - бархатные напильники с числом зубьев на 1 см длины 25-80 (самая мелкая насечка).

Напильники могут иметь одинарную или двойную (перекрестную) насечку.

Применение напильников того или иного класса зависит от характера выполняемой работы, т. е. от толщины снимаемого слоя металла и от требуемой точности обработки.

Why are files of the same shape made with notches of different depths?

The depth of notches on files of the same shape can vary for several reasons. Here are a few possible explanations:

1. Different applications: Files are used for a wide range of applications, including woodworking, metalworking, and shaping various materials. The depth of the notches on a file can be designed to suit the specific requirements of each application. For example, a file used for rough shaping may have deeper notches to remove material quickly, while a file used for finishing work may have shallower notches to provide a smoother finish.

2. Material hardness: Different materials have different hardness levels, and the depth of notches on a file can be adjusted to match the hardness of the material being worked on. Harder materials may require deeper notches to effectively remove material, while softer materials may require shallower notches to prevent excessive material removal.

3. User preference: The depth of notches on a file can also be a matter of personal preference for the user. Some individuals may prefer files with deeper notches for more aggressive material removal, while others may prefer files with shallower notches for finer control and precision.

It's important to note that the depth of notches on files can vary between different manufacturers and even within different product lines from the same manufacturer. Therefore, it's always a good idea to choose a file with the appropriate notch depth for the specific task at hand.
