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.

数控切割机上的直线导轨和直线轴是数控切割机的核心部件之一。它的功能是指导和支持。为保证数控切割机加工精度高，需求导轨和直线具有较高的导向精度和较好的运动稳定性。

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.

较遍及的是由平面导轨，直线导轨以及循环滚子和平面导轨的组合形成的滚动体引导件。尽管有多种类型的导轨，但大部分的工作特性是相同的，为载体提供了一个润滑的移动外表。处理由机床切削产生的力以减小对被迫加工零件的影响。

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.

大多数导轨是直线运动，少量是弧形运动。直线导轨经过精确的加工程序与滚珠相结合。其运动速度快，摩擦系数小，灵敏度高，满足运动部件的工作要求。滚动体怎么与轨迹外表触摸是较直接影响系统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.

直线导轨能够使CNC切割机取得快速进给速度。在主轴转速相同的情况下，快速进给是直线导轨的特征。那么咱们需求怎么调整直线导轨？

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?

具体操作如下：

The specific operation is as follows:

1.在导轨两头拧紧1 / 2000mm规范钢丝，调整导轨上两个导向板上的调整螺钉，使导轨两边与规范钢丝之间的间隔为a必定的值，并将此间隔用作规范间隔。

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，拉伸精度为1 / 2000mm的钢卷尺，两头主，副导轨之间的间隔应为机器的跨度，不然运用整根导线调整导轨，同时调整导线以保证规范间隔不会改变。

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毫米的精度测量主导轨和副导轨两头的平整度，并调整导螺栓的高度以调整高度，使主导轨和副导轨的平整度两头的导轨保持在0.5毫米以内。

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.运用压板紧缩端部的每个主轨迹和辅佐轨迹，作为调整轨迹水平缓笔直水平状态的根底，主轨迹和副轨迹的平坦度以及主轨迹和副轨迹之间的间距子导轨。钢轨的直线度是钢。导线和导轨旁边面之间的规范间隔是参考。

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.用调理销和探针脚逐一调理每个主导轨两头和规范钢丝绳之间的间隔，并将其调整到规范间隔。

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.运用气泡调平器调整导轨的水平缓笔直水平。从导轨的一端逐渐校准到另一端，然后测量两个导轨的接头，以保证它们处于水平位置。

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.校准主，辅导轨后，当心拧紧导轨间的连接螺栓，用压板压住导轨。仔细检查导轨是否允许移动或变形。导轨接头的水平缓旁边面应保持润滑。

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.
