说到冲压件加工的话我们会不由自主的想到汽车冲压件，在汽车工业不断发展的环境系，不仅汽车的功能越来越多变，对其任何一个零部件的要求也越来越高，而汽车冲压件就很好的充当了这样一个角色，使得汽车能够更安全的运行。

Speaking of stamping parts processing, we can not help but think of automotive stamping parts. In the environment of the automotive industry, not only the functions of automobiles are changing more and more, but also the requirements for any one of their components are getting higher and higher. The automotive stamping parts play such a role very well, making the automobile safer. Run.

所谓的汽车冲压件，其实就是安装在汽车上面的金属冲压件，我们必须充分认识到它在汽车中起到的巨大作用，尤其是对于汽车的有效运转来说。

The so-called automotive stamping parts, in fact, is the metal stamping parts installed on the automobile, we must fully realize that it plays a huge role in the automobile, especially for the effective operation of the automobile.

冲压件要从两方面来认识，一方面是冲压件经过冲压之后直接成为汽车的零部件；而另外一方面就是在经过冲压之后，还需要经过焊接等加工方式才可以使用的汽车零部件，它们的制作工序是不同的。

Stamping parts should be understood from two aspects. On the one hand, stamping parts become automotive parts directly after stamping; on the other hand, after stamping, automotive parts can be used by welding and other processing methods. Their manufacturing processes are different.

但无论是哪一种，汽车冲压件在制作的时候都要经过油石打磨这一环节，由于冲压件是靠压力机和模具对板材、带材、管材和型材等施加外力，经过塑性变形或分离之后才成型的一种工件，因此表面有可能存在不符合要求的地方，这时候就需要油石打磨。

However, no matter what kind of workpiece, the automobile stamping part must be polished by oil stone. Because the stamping part is a kind of workpiece which is formed after plastic deformation or separation by external force exerted on the sheet, strip, pipe and profile by the press and die, the surface may not meet the requirements. Square, this time needs the oil stone to polish.
