This product overcomes the shortage of limited conversion space of machine tools used in the past in China. It uses a large precision boring and milling machine to complete the processing in one time to ensure the accuracy of the machine tool, saving time, labor and labor, high efficiency, about 60 strokes per minute, a production line Only two large and two small machines of this machine are needed for operation by four persons. Compared with the original process, the labor is too much, and the accuracy stability is insufficient, the advantages are obvious. It can produce the most accurate high-tech products such as photovoltaic frames. With a qualitative leap forward, it has entered the international advanced technology industry, and the combination of photovoltaics will have a brighter future.
