Explore the road to grinding through the centuries

Abrasive belt, as an important grinding tool, has played an irreplaceable role in industrial production. Its development process can be traced back to nearly a century ago, and it has experienced continuous technological innovation and improvement.

The emergence of early sand belts

In the early 20th century, with the rise of industrial production, the demand for grinding tools is growing. The original belt was usually backed by cloth, to which abrasive particles (usually sand, diamond, etc.) were attached. Although this simple sand belt can be used for basic grinding, there are some defects in the process of use, such as the abrasive particle is easy to fall off and the life is short.

The appearance of adhesive sand belts

In the 1920s, adhesive sand belts began to appear. The backing of the belt is usually made of paper or cloth, and the abrasive particles are fixed to the backing by adhesive. The adhesive belt has higher stability and life span than the earlier belt, allowing for more fine grinding.

The emergence of synthetic resin sand belts

With the development of chemical industry, synthetic resin as a new adhesive began to be widely used in the manufacture of sand belt. The synthetic resin sand belt has the advantages of strong adhesion and high wear resistance, which greatly improves the performance and service life of the sand belt. At the same time, the emergence of synthetic resin sand belt has also promoted the innovation of abrasive materials, such as silicon carbide, alumina and other new abrasive gradually replaced the traditional sand and diamond, so that the grinding effect of sand belt has been further improved.

The emergence of automated grinding technology

With the development of mechanized and automated production technology, belt grinding technology has been continuously improved and perfected. The emergence of automatic abrasive belt grinding equipment has further expanded the application range of abrasive belt, which can not only be applied to traditional manual operation, but also can be widely used in automated production lines, improving production efficiency and product quality.

The future of the sand belt

With the continuous development of the manufacturing industry and the progress of technology, sand belt as an important grinding tool, its development prospects are still broad. In the future, with the continuous innovation in materials science, mechanical engineering and other fields, the sand belt will be more intelligent, fine and environmentally friendly, providing more reliable grinding solutions for the production of various industries.
