絲桿和導軌精度等級的基本定義師比較模糊的，大體的意思是為了反映出滾動體及相關組件的在不同配合間隙的情況下，導致的直線導軌定位面與基準面，或者絲杠的重復定位精度上出現的不同差異。如果你能理解滾珠絲杠在伺服系統中以及直線導軌在起精密導向元件時的作用的話，這個“精度等級”的概念就不難理解，說白了，高精度的絲桿就可以用在高精度的設備，當然高精度的絲桿也不菲。

The basic definition of precision level of screw rod and guide rail is rather vague, which generally means to reflect the different differences between the positioning surface and reference surface of linear guide rail, or the repeated positioning accuracy of screw rod caused by the different fit clearance of rolling element and related components. If you can understand the role of the ball screw in the servo system and the linear guide in the precision guiding element, the concept of "precision level" is not difficult to understand. To put it bluntly, the high-precision screw can be used in high-precision equipment, and of course, the high-precision screw is expensive.

于這些指標，廠家有專門的測試設備給出結果，反映在這些客戶眼中呢，我們只需要關心產品樣本中寫的行業內通用的標識即可。這些標識有的不同廠家叫法還可能不同。比如有的叫“普通級”，有的叫“一般級”，這樣不同的叫法只是相對于自己廠家的“精密級”而言的，為了對比不同廠家之間的產品，我們較好還是看那些術語吧。

As for these indicators, the manufacturer has special test equipment to give the results, which are reflected in the eyes of these customers. We only need to care about the general identification in the industry written in the product samples. Some of these signs are called differently by different manufacturers. For example, some are called "ordinary level", some are called "ordinary level", so different terms are only relative to the "precision level" of their own manufacturers. In order to compare the products of different manufacturers, we'd better look at those terms.

比如滾珠絲杠，有個“e300”和“e2π”這是行業通用的參數，下面地址是個pdf頁面，有說明，但是他用的是“v300”和“v2π”是一樣的。

For example, the ball screw has "E300" and "E2 π", which are common parameters in the industry. The address below is a PDF page with instructions, but it uses "V300" and "V2 π", which are the same.
