The metal bending process is a precise process. According to different metal materials, it can be divided into iron, aluminum, stainless steel, etc., the most common of which is sheet metal bending, so as to produce a variety ofmetal bending parts . Sheet metal bending is to bend the sheet metal into the required angle by metal processing machine tools, which is often used in production engineering, building structures, reinforcing ribs and other businesses.Metal bending technology is widely used in engineering manufacturing, construction, electric power, automobile, aerospace, health care and many other fields. With the continuous development of mechanical automation and digital technology, the emergence of automatic bending machines has greatly improved the efficiency and precision of custom metal bending parts, making the metal bending process enter a new stage.
