News of the European auto parts manufacturers to see the news accidentally discovered so that the automotive screw fastener industry was shocked news, not only shocked the same screw fastener also made a reflection of the car, the original human long before long ago It will have produced the production of car screws, and have lamented the human wisdom is how broad and profound. At that time there was not only no intelligent creatures on Earth, nor even dinosaurs. How did this car screw appear? Are human errors of judgment or hearsay lies?
In the summer of 1998, Russian scientists discovered a piece of rock with iron screws embedded in a meteorite site 300 kilometers southwest of Moscow. Geologists estimate that the rock has been between 3 and 320 million years old. This nut and thread clearly visible screws, about 1 cm in diameter and about 3 mm. At first, scientists thought the screw was on an agricultural machine. But the screw is solidly nailed to the rock. Some possible mistakes have been ruled out, as subsequent studies show that the screw has really existed for a long time.
Seen in this light, the screws appeared very early. At present, all production enterprises basically have high levels of automation and intelligence. To give full play to their advantages in independent innovation, they should vigorously develop information technology and high-tech applications to enlarge the product structure, complicate mechanical parts, and make the production process more efficient. Product testing automation and manufacturing technology intensive services.
