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.

一般的导轨丝杠分为非互换性与互换性两种线性滑轨，两者规格尺寸相同，主要差距是在于互换性之滑块，滑轨可单独互换使用，相对来说便利性也好，但是它的组合精度无法连到非互换性之超精密级以上的精度，不过由于HIWIN互换性之组合精度目前已达到一定的水准，对不需配对安装线性滑轨的客户而言，是一项便利的选择。

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

.

线性滑轨的产品规格型号主要表明线性滑轨尺寸，形式，精度等级，预压等规格要求，以利订货时间方面的产品的确认。单轴滑轨数若只使用一只滑轨则不用，两支可以用。HIWIN提供法兰性以及四方性两种线性滑轨，四方型线性滑轨分H型L型，L型为H型之低组装式线性滑轨，其组合高度与法兰型的线性滑轨一致。

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.

总之，一般客户给到实物，我们可以从客户的实物上面测量几个尺寸就可以从中得出客户想要的导轨滑块的型号，规格。一般来说我们这个要和客户具体的沟通。

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.
