直线导轨是数控切割机较重要的部分。它是用于线性往复运动的东西。该东西具有以前的直线轴承所没有的较高的额外载荷，并且还能够承当必定的负载。扭矩还能够在高负载条件下实现高精度的直线运动，使设备平稳，准确地运行。

Linear guide is an important part of CNC cutting machine. It's something for linear reciprocating motion. It has a higher additional load than the previous linear bearing, and can also bear a certain load. Torque can also achieve high-precision linear motion under high load conditions, so that the equipment runs 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。

The linear guide and linear axis of CNC cutting machine is one of the core components of CNC cutting machine. Its function is guidance and support. In order to ensure high machining accuracy of CNC cutting machine, guide rail and straight line are required to have higher guiding accuracy and better motion stability.

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。

More widely by the plane guide, linear guide and the combination of circular roller and plane guide to form a rolling element guide. Although there are many types of guides, most of the operating characteristics are the same, providing a lubricating moving surface for the carrier. To deal with the force generated by the machine tool cutting to reduce the impact on the forced processing 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 guide rail is linear motion, a small number of arc motion. The linear guide is combined with the ball through the precise machining procedure. It has the advantages of high speed, small friction coefficient and high sensitivity, which can meet the working requirements of moving parts. How to touch the surface of the rolling element with the track is one of the main 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？

The linear guide can make the CNC cutting machine achieve fast feed speed. In the case of the same spindle speed, rapid feed is the feature 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 standard steel wire at both ends of the guide rail, adjust the adjusting screws on the two guide plates on the guide rail, so that the interval between both sides of the guide rail and the standard steel wire is a certain value, and use this interval as the standard 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. For the steel tape with tensile force of 20n and drawing accuracy of 1 / 2000mm, the interval between the main and auxiliary guide rails at both ends shall be the span of the machine, otherwise, the whole wire shall be used to adjust the guide rail, and the wire shall be adjusted at the same time to ensure that the standard interval 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 guide rail and the auxiliary guide rail with the accuracy of 1 / 10000 mm, and adjust the height of the guide bolt to adjust the height, so that the flatness of the two ends of the main guide rail and the auxiliary guide rail is kept within 0.5 mm.

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 track and auxiliary track at the compression end of the pressing plate are used as the basis for adjusting the horizontal state of the track, the flatness of the main track and the auxiliary track, and the spacing between the main track and the auxiliary track. The straightness of rail is steel. The gauge interval between the conductor and the side surface 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. Adjust the interval between the two ends of each main guide rail and the standard wire rope one by one with the adjusting pin and probe foot, 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 leveler to adjust the level of guide rail. Gradually align the rails from one end to the other, and then measure the joints of the two rails 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 main and guide rails, carefully tighten the connecting bolts between the guide rails, and press the guide rails with pressing plates. Carefully check whether the guide rail is allowed to move or deform. The horizontal surface of the rail joint shall be lubricated.
