This morning, a customer sent a picture of the guide screw and asked our business to confirm the model for him, but nothing could be seen from the picture. Then my colleague asked the customer to measure some specific sizes, and then confirmed it to the customer. Of course, this kind of situation is often encountered in our actual use process, so how should we solve this problem for customers? Next, we will understand it from several aspects.

一般的導軌絲杠分為非互換性與互換性兩種線性滑軌，兩者規格尺寸相同，主要差距是在于互換性之滑塊，滑軌可單獨互換使用，相對來說便利性也好，但是它的組合精度無法連到非互換性之超精密級以上的精度，不過由于HIWIN互換性之組合精度目前已達到一定的水準，對不需配對安裝線性滑軌的客戶而言，是一項便利的選擇。

The general guide screw is divided into two kinds of linear slide rails, non interchangeability and interchangeability. The specifications and sizes of the two are the same. The main difference lies in the interchangeability of the slider. The slide rail can be used interchangeably alone, which is relatively convenient. However, its combined accuracy can not reach the accuracy above the ultra precision level of non interchangeability. However, due to the interchangeability of HIWIN, the combined accuracy has reached a certain level It is a convenient choice for customers who do not need to install linear slide rails

.

線性滑軌的產品規格型號主要表明線性滑軌尺寸，形式，精度等級，預壓等規格要求，以利訂貨時間方面的產品的確認。單軸滑軌數若只使用一只滑軌則不用，兩支可以用。HIWIN提供法蘭性以及四方性兩種線性滑軌，四方型線性滑軌分H型L型，L型為H型之低組裝式線性滑軌，其組合高度與法蘭型的線性滑軌一致。

The specification and model of linear slide rail mainly indicate the dimension, form, accuracy grade, preloading and other specification requirements of linear slide rail, so as to facilitate the confirmation of ordering time. If only one slide rail is used, two can be used. HIWIN provides flange type and square type linear slide rails. The square type linear slide rail is divided into H-type and L-type. The L-type is a low assembly type linear slide rail of H-type, and its combination height is consistent with that of flange type linear slide rail.

總之，一般客戶給到實物，我們可以從客戶的實物上面測量幾個尺寸就可以從中得出客戶想要的導軌滑塊的型號，規格。一般來說我們這個要和客戶具體的溝通。

In short, the general customer to the physical, we can measure a few dimensions from the customer's physical above, we can get the customer want the guide slider model, specification. Generally speaking, we need to communicate with customers.
