中法合资淮阴盖克斯工具制造有限公司新近建成了一条冲击钻生产线,该线可年产φ3～14mm 冲击钻头2000万件。该生产线的最大特点是螺旋槽不用传统的铣削或热轧工艺,而在国内首次使用了冷轧成形的新工艺,故使铝头产品的质量和机械性能均有明显提高。 Sino-French joint venture Huaiyin Gax Tool Manufacturing Co., Ltd. recently built a production line of impact drilling, the line can produce an annual output of φ3 ~ 14mm impact drill 20 million. The most prominent feature of this production line is that the spiral groove does not use the traditional milling or hot-rolling process, but the first cold-rolling forming process is used in China. Therefore, the quality and mechanical properties of the aluminum head product are obviously improved.
