說到沖壓件加工的話我們會不由自主的想到汽車沖壓件，在汽車工業不斷發展的環境系，不僅汽車的功能越來越多變，對其任何一個零部件的要求也越來越高，而汽車沖壓件就很好的充當了這樣一個角色，使得汽車能夠更安全的運行。

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.

所謂的汽車沖壓件，其實就是安裝在汽車上面的金屬沖壓件，我們必須充分認識到它在汽車中起到的巨大作用，尤其是對于汽車的有效運轉來說。

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.

沖壓件要從兩方面來認識，一方面是沖壓件經過沖壓之后直接成為汽車的零部件；而另外一方面就是在經過沖壓之后，還需要經過焊接等加工方式才可以使用的汽車零部件，它們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.

但無論是哪一種，汽車沖壓件在制作的時候都要經過油石打磨這一環節，由于沖壓件是靠壓力機和模具對板材、帶材、管材和型材等施加外力，經過塑性變形或分離之后才成型的一種工件，因此表面有可能存在不符合要求的地方，這時候就需要油石打磨。

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.
