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(shù)控切割機(jī)上的直線(xiàn)導(dǎo)軌和直線(xiàn)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(xiàn)具有較高的導(dǎo)向精度和較好的運(yùn)動(dòng)穩(wěn)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(dǎo)軌，直線(xiàn)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(lèi)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(rùn)滑的移動(dòng)外表。處理由機(jī)床切削產(chǎn)生的力以減小對(duì)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(shù)導(dǎo)軌是直線(xiàn)運(yùn)動(dòng)，少量是弧形運(yùn)動(dòng)。直線(xiàn)導(dǎo)軌經(jīng)過(guò)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(mǎn)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 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(xiàn)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(xiàn)導(dǎo)軌的特征。那么咱們需求怎么調(diào)整直線(xiàn)導(dǎo)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(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 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(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(xiàn)調(diào)整導(dǎo)軌，同時(shí)調(diào)整導(dǎo)線(xiàn)以保證規(guī)范間隔不會(huì)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(cè)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?xún)?nèi)。

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(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(xiàn)度是鋼。導(dǎo)線(xiàn)和導(dǎo)軌旁邊面之間的規(guī)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(diào)理銷(xiāo)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. 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(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(cè)量?jī)蓚€(gè)導(dǎo)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(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(rùn)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.
