Guide rail is generally used in linear reciprocating motion. It has a higher rated load than linear bearing, and can bear a certain torque. It can realize high-precision linear motion under high load. The high-precision guide rail can improve the product quality through the high-precision motion track.

一：直线导轨精准密度不牵涉要求

1： Precision density of linear guide rail does not involve requirements

在生产制造与运用导轨时，对于各项精准密度做到互不影响的地步才可以得到整体导轨的精密度！例：两列式导轨的直线性是否与周围导轨的直线性是否有冲突，是否可以到达互不干涉的地步。如果达到了互不干涉的地步那么就可以使得导轨横向的尺度改变而不会影响到主导轨的运行密度了。

When manufacturing and using the guide rail, the precision of the whole guide rail can be obtained only when the precision density of each item does not affect each other! For example: whether the linearity of the two row guide rail conflicts with the linearity of the surrounding guide rail, and whether it can reach the point of non-interference. If mutual interference is achieved, the horizontal dimension of the guide rail can be changed without affecting the running density of the main guide rail.

二：导轨能否达到间隙贴合

2： Whether the guide rail can achieve clearance fit

想让导轨的精度高，就使导轨拥有自动贴合的性质，如线性导轨就可以靠活动构件来自动冲量间隙，达到契合度，而其他的导轨上也安装上绷簧，这样就可以使得导轨与其他元件的间隙契合度达到。

In order to achieve high precision of the guide rail, the guide rail has the property of automatic fitting. For example, the linear guide rail can automatically impulse the gap by moving components to achieve the degree of fit, while other guide rails are also installed with tension springs, so that the gap fit between the guide rail and other components can be achieved.

三：导轨是否具备抗压性与抗热性

3： Whether the guide rail has compression resistance and heat resistance

众所周知导轨与其他部件的承受力和温度抗衡力都是不同的，所以导轨作为主要配件，其抗压力与抗热性一定要比其他元件高。

As we all know, the bearing force and temperature resistance of the guide rail and other components are different, so the guide rail, as a main accessory, must have higher resistance to pressure and heat than other components.

四：直线导轨摩擦导致因子接近！

4： Linear guide rail friction causes the factor to approach!

假设导轨对导轨接触面的运动、静态摩擦时，银子权利接近，主要目的是以便于取得更高的重复高精密度定位于地上性。在这一点上，导轨系统安装塑料板或者塑料片都可以达到在摩擦因子时降低噪音，使得因子接近！

It is assumed that when the guide rail is in motion and static friction with the guide rail contact surface, the silver right is close, and the main purpose is to obtain higher repeated high-precision positioning on the ground safety. At this point, the installation of plastic plates or plastic sheets in the guide rail system can reduce the noise when the friction factor is close!

五：直线导轨差错补偿原则

5： Error compensation principle of linear guideway

1.导轨在制作中差错应该小于或等于中间性弹性。

1. the error of guide rail in manufacturing shall be less than or equal to the intermediate elasticity.

2.导轨间设置中间性弹性环节，如添加一些塑料片躲着皮片等。

2. intermediate elastic links are set between guide rails, such as adding some plastic sheets to hide the sheets.

3.导轨间需要有充足的收紧力，以便于补偿接触差错。

3. sufficient tightening force is required between guide rails to facilitate compensation of contact errors.
