Elderly people who have been engaged in mechanical processing for 14 years came to answer a wave. The quality control of Dalian Machine Tool Plant and Shenyang Machine Tool Plant is simply a shame to China’s manufacturing industry. In 2007, the company bought six GD160 gantry-type CNC drilling machines from Shenyang Machine Tool Factory for more than a year after its establishment in 2007. Anyone who has been engaged in machining knows how simple the structure of this machine tool is. However, even such a simple structure can’t be done well. The spindle of a hole with a diameter of more than 20 starts to jump, resulting in hard alloy drills and U drills with internal cooling that are almost never used from the time of purchase to scrapping, because of the damage rate of the drill. Sorry, only high-speed steel drill bits can be used. The manual says that the fastest speed is 20000MM per minute, but when the parameters are given to 15000, the motor load reaches 100%, and the manufacturer has repaired it three times in more than a year. At that time, the overall poor quality control of China’s machinery industry can be forgiven. In 15 years, the company bought two more. This time the problem of spindle beating was solved, and the problem of the false standard of walking speed was still not solved. Designed with a speed of 20000MM per minute, the load will soar to 100% when the parameters are given to 15000MM. The continuity screw is damaged, and the manufacturer’s engineers can’t solve it. Now our company still buys domestic machine tools. The large-scale automatic laser cutting machine is made in Wenzhou, the large-scale five-axis machining center is made in Ningbo, and the ordinary gantry machining center and Lijia are made in Suzhou. The name is not to mention the province. Said I advertise, the quality and processing precision are by no means inferior to Japan and South Korea, but the price is much cheaper. European machine tools have not been used badly. The rapid development of China’s machine tool industry in recent years is undoubtedly, but in the process of development, Shenyang Machine Tool Plant and Dalian Machine Tool Plant have eliminated the unintended corpse-bit vegetarian garbage.
