To be exact, when it is necessary to spline the straight rail, the clearance of joint operation shall not exceed 1 / 3 of the diameter of steel ball used, and the difference shall be minimized. In general, the straight cutting interface can be straight cut; special points need to use concave convex, T-shaped interface end face.

　　安裝拼接式直線導軌時，應非常注意安裝面平行度:

　　When installing the splicing linear guide rail, pay special attention to the parallelism of the installation surface:

　　1. 保證基礎安裝基準和橫向基準的平直度。對接后高度差越小越好。

　　1. Ensure the straightness of foundation installation datum and transverse datum. The smaller the height difference after docking, the better.

　　2. 將導軌固定在底座上時，擰緊安裝螺絲，以保證連接處間隙小，上下左右兩側無錯位。然后完全鎖定安裝螺絲。

　　2. When fixing the guide rail on the base, tighten the mounting screws to ensure that the gap at the connection is small and there is no dislocation at the left and right sides. Then fully lock the mounting screws.

　　3、以一導軌安裝為基準，第二表安裝，保證兩導軌平行。注意不要弄斷導軌的端面，否則滑塊將不能平穩運行市場上常用的直線導軌有:矩形、三角形、燕尾形和圓柱形等。

　　3. Based on the installation of the first guide rail, the second table is installed to ensure that the two guide rails are parallel. Pay attention not to break the end face of the guide rail, otherwise the slider will not run smoothly. The common linear guide rails on the market are: rectangle, triangle, dovetail, cylinder, etc.

　　矩形導軌分為凹型和凸型兩種，兩種形狀的直線導軌可以相互組合。凸導軌不容易積存潤滑油，當然也不容易積存較多的雜物和污垢，所以多用于低速運動和不易保護的部位;凹面導軌正好相反，所以凹面導軌是用來移動較快的零件，但建議有防屑保護裝置。

　　The rectangular guide rail can be divided into concave type and convex type. The linear guide rail with two shapes can be combined with each other. Convex guide rail is not easy to accumulate lubricating oil, of course, it is not easy to accumulate more debris and dirt, so it is mostly used for low-speed movement and parts that are not easy to protect; concave guide rail is just the opposite, so concave guide rail is used for moving faster parts, but it must have anti chip protection device.

　　由于三角導軌依靠其兩側導軌，所以磨損可以自動補償，所以其導向精度高。導向精度隨頂角的提升而減小。軸承面積隨著頂角的提升而提升。頂角通常是900度;在受力較大的機械系統中，頂角為110 ~ 1200。對于精度較高的機械系統，頂角通常小于90度，因此三角導軌的加工、檢測和維護比較困難。

　　Because the triangular guide depends on the guide rails on both sides, the wear can be compensated automatically, so its guide precision is high. The guidance accuracy decreases with the increase of the vertex angle. The bearing area increases with the increase of top angle. The top angle is usually 900 degrees; in mechanical systems with large forces, the top angle is 110 ~ 1200. For the mechanical system with high precision, the top angle is usually less than 90 degrees, so it is difficult to process, detect and maintain the triangular guide rail.

　　矩形導軌剛度和承載能力大，等效摩擦系數低于三角形導軌。制造、調整、檢查、維修都很方便，但經過側面磨損后不能自動補償，所以建議有間隙調整裝置。

　　The stiffness and bearing capacity of rectangular guide rail are large, and the equivalent friction coefficient is lower than that of triangular guide rail. It is very convenient to manufacture, adjust, check and maintain, but it can't compensate automatically after side wear, so there must be a gap adjustment device.

　　線性導軌能承受傾覆力矩，可用于調節水平和垂直間隙。這種直線導軌剛性較差，摩擦、制造、檢驗、維修都比較復雜。一般主要用于運動件的多層，受力小，間隙調整方便。

　　Linear guide rail can bear overturning moment, and can be used to adjust horizontal and vertical clearance. The rigidity of this kind of linear guide rail is poor, and its friction, manufacture, inspection and maintenance are complex. Generally, it is mainly used for multi-layer moving parts, with small stress and convenient clearance adjustment.
