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.

　　安装拼接式直线导轨时，应特别注意安装面平行度:

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

　　1. 保证基础安装基准和横向基准的平直度。对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. 将导轨固定在底座上时，拧紧安装螺丝，以保证连接处间隙小，上下左右两侧无错位。然后完全锁定安装螺丝。

　　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、以一导轨安装为基准，第二表安装，保证两导轨平行。注意不要弄断导轨的端面，否则滑块将不能平稳运行市场上常用的直线导轨有:矩形、三角形、燕尾形和圆柱形等。

　　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.

　　矩形导轨分为凹型和凸型两种，两种形状的直线导轨可以相互组合。凸导轨不容易积存润滑油，当然也不容易积存较多的杂物和污垢，所以多用于低速运动和不易保护的部位;凹面导轨正好相反，所以凹面导轨是用来移动较快的零件，但必须有防屑保护装置。

　　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.

　　由于三角导轨依靠其两侧导轨，所以磨损可以自动补偿，所以其导向精度高。导向精度随顶角的增大而减小。轴承面积随着顶角的增大而增大。顶角通常是900度;在受力较大的机械系统中，顶角为110 ~ 1200。对于精度较高的机械系统，顶角通常小于90度，因此三角导轨的加工、检测和维护比较困难。

　　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.

　　矩形导轨刚度和承载能力大，等效摩擦系数低于三角形导轨。制造、调整、检查、维修都很方便，但经过侧面磨损后不能自动补偿，所以必须有间隙调整装置。

　　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.

　　线性导轨能承受倾覆力矩，可用于调节水平和垂直间隙。这种直线导轨刚性较差，摩擦、制造、检验、维修都比较复杂。一般主要用于运动件的多层，受力小，间隙调整方便。

　　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.
