哈希私彩Parts processing is an important part of modern machining and manufacturing technology. It is one of the important indicators to measure the level of a country's high-tech manufacturing industry. Since the 1960s, with the development of computer and information technology, higher requirements have been put forward for manufacturing technology, which requires not only high dimensional and positional accuracy, but also high surface quality. Precision forming technology has been widely used in industrial developed countries. Through cooperation with advanced process equipment and detection means, precision forming manufacturing units of different grades have been formed, and generally replaced the traditional forming process and equipment.
