Description

Technical Field

[0001] The utility model belongs to the technical field of rounded corner grinding devices, in particular to a rounded corner grinding device for hardware processing. Background Art

[0002] Corner-rounding grinding devices for hardware processing play a vital role in hardware manufacturing and processing. Corner-rounding grinding removes burrs, sharp edges, and uneven surfaces, especially at rounded corners, making the surface smoother and flatter, thereby improving the hardware's appearance and tactile quality. During hardware assembly, corner-rounding grinding can help reduce friction and resistance during assembly, making assembly smoother and more precise. Corner-rounding grinding can also help improve the fit between hardware and other components, thereby enhancing the stability and reliability of the entire product. For hardware that comes into direct contact with the human body, such as furniture hardware and decorative hardware, corner-rounding grinding can enhance the user's tactile experience. Smooth corners not only enhance aesthetics but also reduce friction and discomfort with the skin. Corner-rounding grinding can also reduce wear and damage caused by friction, collisions, and other factors during use, thereby extending the hardware's service life. However, existing corner-rounding grinding devices cannot adjust the length of the sanding belt according to the size of the corners, making them unsuitable for different sizes and resulting in poor performance.
