空见惯的事，而工艺的复杂性也比较高，甚至有些零件工序达到几十道之多。所以金加工企业通 常需要各种各样的机械设备以满足不同工艺要求。而钣金冲孔精度一般在±0.1mm左右，折弯精度一般可以达到±0.5mm，因此相对于金加工来说，精度低 得多。
Overall, in recent years, the sheet metal processing industry is developing rapidly, of course, how about sheet metal processing.
This is mainly due to the following reasons.
1, the profit is high. For example, stamping can reach about 30%, and laser cutting can achieve 50% or more.
2, the machining precision is low, and the upper hand is easy. As far as gold processing is concerned, the precision is in a few silk.
The technology is complicated, and even some parts work in dozens of ways. Therefore, gold processing enterprises usually need a variety of mechanical equipment to meet different technological requirements. The punching accuracy of sheet metal is usually about 0.1mm, and the bending accuracy can reach 0.5mm. Therefore, the accuracy is much lower than that of gold processing.
3, the demand for production capacity is improved. China has become more and more international manufacturing center, with the increase of foreign investment, the demand for metal processing capacity is increasing, and the electrical control box and machine shell in the metal processing industry are generally sheet metal parts, so the demand for sheet metal processing ability is also increasing.
