Linear guide is the most important part of NC cutting machine. It is used for linear reciprocating motion. It has a higher additional load than previous linear bearings, and can also bear a certain load. Torque can also achieve high precision linear motion under high load conditions, so that the equipment can run smoothly and accurately.

數控切割機上的直線導軌和直線軸是數控切割機的核心部件之一。它的功能是指導和支持。為保證數控切割機加工精度高，需求導軌和直線具有較高的導向精度和較好的運動穩定性。

Linear guideway and linear axis on NC cutting machine are one of the core components of NC cutting machine. Its function is guidance and support. In order to ensure the high machining accuracy of NC cutting machine, it is necessary to have high guiding accuracy and good motion stability of guide rail and straight line.

較遍及的是由平面導軌，直線導軌以及循環滾子和平面導軌的組合形成的滾動體引導件。盡管有多種類型的導軌，但大部分的工作特性是相同的，為載體提供了一個潤滑的移動外表。處理由機床切削產生的力以減小對被迫加工零件的影響。

The most common is the rolling body guides formed by the combination of planar guides, linear guides, cyclic rollers and planar guides. Although there are many types of guideways, most of the working characteristics are the same, providing a lubricated mobile appearance for the carrier. Deal with the forces generated by machine tool cutting to reduce the impact on the forced parts.

大多數導軌是直線運動，少量是弧形運動。直線導軌經過準確的加工程序與滾珠相結合。其運動速度快，摩擦系數小，靈敏度高，滿足運動部件的工作要求。滾動體怎么與軌跡外表觸摸是較直接影響系統功能的主要因素之一。

Most of the guideways move in straight line, while a few move in arc. Linear guides are combined with balls through precise processing procedures. Its motion speed is fast, friction coefficient is small and sensitivity is high, which meets the working requirements of moving parts. How the rolling element touches the surface of the track is one of the most important factors that directly affect the function of the system.

直線導軌能夠使CNC切割機取得快速進給速度。在主軸轉速相同的情況下，快速進給是直線導軌的特征。那么咱們需求怎么調整直線導軌？

Linear guide can make CNC cutting machine get fast feed speed. In the case of the same spindle speed, fast feed is the characteristic of linear guide. So how do we need to adjust the linear guide?

具體操作如下：

The specific operation is as follows:

1.在導軌兩頭擰緊1 / 2000mm規范鋼絲，調整導軌上兩個導向板上的調整螺釘，使導軌兩邊與規范鋼絲之間的間隔為a必定的值，并將此間隔用作規范間隔。

1. Tighten the 1/2000mm gauge steel wire at both ends of the guide rail and adjust the adjusting screw on the two guide plates so that the interval between the two sides of the guide rail and the gauge steel wire is a certain value, and use this interval as the gauge interval.

2，用20N的拉力，拉伸精度為1 / 2000mm的鋼卷尺，兩頭主，副導軌之間的間隔應為機器的跨度，不然運用整根導線調整導軌，同時調整導線以保證規范間隔不會改變。

2. With 20N pulling force and 1/2000mm steel tape with drawing precision, the spacing between the main and auxiliary guide rails at both ends should be the span of the machine. Otherwise, the whole wire should be used to adjust the guide rails, and the wire should be adjusted to ensure that the standard spacing will not change.

3.以1/10000毫米的精度測量主要軌和副導軌兩頭的平整度，并調整導螺栓的高度以調整高度，使主要軌和副導軌的平整度兩頭的導軌保持在0.5毫米以內。

3. Measure the flatness of the two ends of the main rail and the auxiliary rail with the accuracy of 1/10000mm, and adjust the height of the guide bolt to adjust the height, so that the flatness of the two ends of the main rail and the auxiliary rail can be kept within 0.5mm.

4.運用壓板緊縮端部的每個主軌跡和輔佐軌跡，作為調整軌跡水平緩筆直水平狀態的根底，主軌跡和副軌跡的平坦度以及主軌跡和副軌跡之間的間距子導軌。鋼軌的直線度是鋼。導線和導軌旁邊面之間的規范間隔是參考。

4. Each main and auxiliary trajectories at the tightening end of the press plate are used as the basis for adjusting the horizontal state of the trajectory, the flatness of the main and secondary trajectories, and the spacing between the main and secondary trajectories. The straightness of the rail is steel. The standard interval between the conductor and the side of the guide rail is a reference.

5.用調理銷和探針腳逐一調理每個主要軌兩頭和規范鋼絲繩之間的間隔，并將其調整到規范間隔。

5. Use conditioning pin and probe foot to adjust the interval between the two ends of each main rail and the standard wire rope one by one, and adjust it to the standard interval.

6.運用氣泡調平器調整導軌的水平緩筆直水平。從導軌的一端逐漸校準到另一端，然后測量兩個導軌的接頭，以保證它們處于水平位置。

6. Use bubble leveller to adjust the horizontal of guide rail. Gradually calibrate from one end of the guide rail to the other end, and then measure the joints of the two guideways to ensure that they are in a horizontal position.

7.校準主，輔導軌后，當心擰緊導軌間的連接螺栓，用壓板壓住導軌。仔細檢查導軌是否允許移動或變形。導軌接頭的水平緩旁邊面應保持潤滑。

7. After calibrating the master and guiding rails, tighten the connecting bolts between the guideways carefully and press the guide rails with a pressure plate. Check carefully whether the guide is allowed to move or deform. Lubrication should be maintained on the horizontal side of the guide joint.
