直線導(dǎo)軌是數(shù)控切割機(jī)較重要的部分。它是用于線性往復(fù)運(yùn)動(dòng)的東西。該東西具有以前的直線軸承所沒有的較高的額外載荷，并且還能夠承當(dāng)必定的負(fù)載。扭矩還能夠在高負(fù)載條件下實(shí)現(xiàn)高精度的直線運(yùn)動(dòng)，使設(shè)備平穩(wěn)，準(zhǔn)確地運(yùn)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.

數(shù)控切割機(jī)上的直線導(dǎo)軌和直線軸是數(shù)控切割機(jī)的核心部件之一。它的功能是指導(dǎo)和支持。為保證數(shù)控切割機(jī)加工精度高，需求導(dǎo)軌和直線具有較高的導(dǎo)向精度和較好的運(yùn)動(dòng)穩(wěn)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.

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

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.

大多數(shù)導(dǎo)軌是直線運(yùn)動(dòng)，少量是弧形運(yùn)動(dòng)。直線導(dǎo)軌經(jīng)過精 確的加工程序與滾珠相結(jié)合。其運(yùn)動(dòng)速度快，摩擦系數(shù)小，靈敏度高，滿足運(yùn)動(dòng)部件的工作要求。滾動(dòng)體怎么與軌跡外表觸摸是較直接影響系統(tǒng)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.

直線導(dǎo)軌能夠使CNC切割機(jī)取得快速進(jìn)給速度。在主軸轉(zhuǎn)速相同的情況下，快速進(jìn)給是直線導(dǎo)軌的特征。那么咱們需求怎么調(diào)整直線導(dǎo)軌？

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?

具體操作如下：

The specific operation is as follows:

1.在導(dǎo)軌兩頭擰緊1/2000mm規(guī)范鋼絲，調(diào)整導(dǎo)軌上兩個(gè)導(dǎo)向板上的調(diào)整螺釘，使導(dǎo)軌兩邊與規(guī)范鋼絲之間的間隔為a必定的值，并將此間隔用作規(guī)范間隔。

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，拉伸精度為1/2000mm的鋼卷尺，兩頭主，副導(dǎo)軌之間的間隔應(yīng)為機(jī)器的跨度，不然運(yùn)用整根導(dǎo)線調(diào)整導(dǎo)軌，同時(shí)調(diào)整導(dǎo)線以保證規(guī)范間隔不會(huì)改變。

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毫米的精度測量主 導(dǎo)軌和副導(dǎo)軌兩頭的平整度，并調(diào)整導(dǎo)螺栓的高度以調(diào)整高度，使主 導(dǎo)軌和副導(dǎo)軌的平整度兩頭的導(dǎo)軌保持在0.5毫米以內(nèi)。

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.運(yùn)用壓板緊縮端部的每個(gè)主軌跡和輔佐軌跡，作為調(diào)整軌跡水平緩筆直水平狀態(tài)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(dǎo)軌。鋼軌的直線度是鋼。導(dǎo)線和導(dǎo)軌旁邊面之間的規(guī)范間隔是參考。

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.用調(diào) 理銷和探針腳逐一調(diào) 理每個(gè)主 導(dǎo)軌兩頭和規(guī)范鋼絲繩之間的間隔，并將其調(diào)整到規(guī)范間隔。

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.運(yùn)用氣泡調(diào)平器調(diào)整導(dǎo)軌的水平緩筆直水平。從導(dǎo)軌的一端逐漸校準(zhǔn)到另一端，然后測量兩個(gè)導(dǎo)軌的接頭，以保證它們處于水平位置。

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.校準(zhǔn)主，輔 導(dǎo)軌后，當(dāng)心擰緊導(dǎo)軌間的連接螺栓，用壓板壓住導(dǎo)軌。仔細(xì)檢查導(dǎo)軌是否允許移動(dòng)或變形。導(dǎo)軌接頭的水平緩旁邊面應(yīng)保持潤滑。

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.
