Recently, the “Special Tool for Machining Circular Grooves†independently developed by Jinglong Group was granted a patent right by the State Intellectual Property Office and issued a “utility model patent†certificate.
In the production process of single crystal silicon, graphite crucible is a necessity, and graphite material for producing antimony is relatively expensive. In the past, the group produced graphite crucibles, which were hollowed out of graphite cylinders, and then sawed, milled, refined, and other processes, resulting in a large amount of raw material waste. To this end, they started with improved machining tools, and after repeated research and testing, they finally designed a tool suitable for the production of circular surfaces. The use of this kind of tool can make a raw material "set" a plurality of graphite crucibles of different specifications, which not only solves the requirements of the new process of graphite crucible production, but also can increase the efficiency by more than ten million yuan per year.
