Introduction To Grinder
Grinding is an ancient technology that mankind has known since ancient times. In the Paleolithic period, this technology was used to polish stone tools. Later, with the use of metal appliances, the development of grinding technology was promoted. However, the design of a veritable grinding machine is still a modern thing. Even in the early 19th century, people still grind by rotating a natural grindstone and letting it touch the processed object.
The first grinder. In 1864, the United States made the world's first grinder, which is a kind of automatic transmission device that is equipped with a grinding wheel on the carriage of the lathe. After 12 years, Brown in the United States invented a universal grinder that was close to modern grinders.
Artificial grinding stone-the birth of grinding wheel (1892). The demand for artificial grinding stones has also risen. How to develop a grinding stone that is more wear-resistant than natural grinding stones? In 1892, American Acheson successfully trial-produced silicon carbide made of coke and sand, which is an artificial grinding stone now called C abrasive; two years later, A abrasive with alumina as the main component was trial-produced Success, in this way, the grinding machine has been more widely used.
Later, due to the further improvement of bearings and guide rails, the accuracy of grinders has become higher and higher, and the direction of professional development has been developed. Internal grinders, surface grinders, roller grinders, gear grinders, universal grinders and so on have appeared.
