Linear guideway control CNC machine tool can control the tool or worktable to move and cut along the direction parallel to the coordinate axis with appropriate feed rate. The feed rate can change in a certain range according to the cutting conditions. The following guide screw small series and you will introduce one of the mysteries.

直线控制的简易数控车床，只有两个坐标轴，可加工阶梯轴。直线控制的数控铣床，有三个坐标轴，可用于平面的铣削加工。现代组合机床采用数控进给伺服系统，驱动动力头带有多轴箱的轴向进给进行钻镗加工，它也可算是一种直线控制数控机床。

Linear control of the simple CNC lathe, only two coordinate axes, can process step axis. CNC milling machine with linear control has three coordinate axes, which can be used for plane milling. Modern modular machine tool adopts CNC feed servo system to drive the axial feed of power head with multiple axle boxes for drilling and boring. It can also be regarded as a kind of linear control CNC machine tool.

数控镗铣床、加工等机床，它的各个坐标方向的进给运动的速度能在一定范围内进行调整，兼有点位和直线控制加工的功能，这类机床应该称为点位/直线控制的数控机床

CNC boring and milling machines, machining centers and other machine tools, the feed movement speed of each coordinate direction can be adjusted within a certain range, and has the function of point position and linear control processing. This kind of machine tool should be called point position / linear control CNC machine tool

导轨丝杠

Guide screw

普通导轨，也叫做硬轨，指的是导轨和床身是一体的铸造件，然后在那基础上加工出导轨，即床身上铸造出导轨的形状，再通过淬火、磨削后加工成的导

Ordinary guide rail, also known as hard rail, refers to the casting part that the guide rail and the bed are integrated, and then the guide rail is processed on that basis, that is, the shape of the guide rail is cast on the bed, and then processed through quenching and grinding

轨，也有床身和导轨不一定一体的，比如镶钢导轨，就是加工后钉接在床身上的。

Rail, also have bed and guide rail is not necessarily integrated, such as inlaid steel guide rail, is after processing nailed on the bed.

数控上用的一般叫线轨，通常指滚动导轨，就是现在机床行业经常用到的线性模组中用到的那种，我们通常称这类元件为“直线导轨”，像台湾的ABBA，日本的THK，台湾的银泰(PMI)、上银(HIWIN)就专门生产这个。直线导轨本身分两部分：滑轨和滑块。滑块内有内循环的滚珠或滚柱，滑轨的长度可以定制。它是一种模块化的元件，是有专门厂家生产的标准化系列化的单独的产品，可以安装在机床上，磨损后可以拆卸下来更换。

CNC commonly used in line rail, usually refers to rolling guide rail, is now often used in the machine tool industry linear module used, we usually call this kind of component as "linear guide", such as Taiwan's Abba, Japan's THK, Taiwan's Yintai (PMI), HIWIN (HIWIN) specialized production of this. The linear guide rail itself is divided into two parts: slide rail and slide block. There are inner circulation balls or rollers in the slider, and the length of the slide can be customized. It is a modular component. It is a standardized series of individual products produced by a special manufacturer. It can be installed on the machine tool and can be disassembled and replaced after wear.

硬轨和线轨是台湾机床业的叫法，不是标准名称，在机械手册上是查不到。

Hard track and line rail are the names of Taiwan's machine tool industry, not standard names. They can't be found in the mechanical manual.

普通机床改数控，导轨换不换，要看原来的导轨能否达到精度要求了。一般情况我觉得原来的床身根本就没有设计安装直线导轨的平面，全部安装直线导轨的改造比较麻烦。一般情况下改造只是保留原来的结构，只安装光栅尺和相应的数显系统而已。

If the ordinary machine tool is changed to numerical control, whether the guide rail can be replaced depends on whether the original guide rail can meet the accuracy requirements. In general, I think that the original bed simply did not design and install the plane of linear guide rail, and the transformation of all the installation of linear guide rail is more troublesome. In general, the original structure is retained and only grating ruler and corresponding digital display system are installed.

硬轨的好还是线轨的好?

Is the hard track better or the line rail better?

加工多用直线滚动导轨，应为它运动速度快，而且滚动阻力小，没有爬行现象，润滑也方便。长时间用后，精度损失较小。镶钢(有的贴塑)导轨，在重载的情况下用的较多。特别是，润滑对它是个很重要的事情。但是导轨磨损后，要调整也很麻烦。现在是线轨的用的比较多，但线轨的宽度是有区别的机床的设计不同就有不同的配置了!

The linear rolling guide rail is often used in machining center because of its high speed, small rolling resistance, no creeping phenomenon and convenient lubrication. After a long time of use, the precision loss is small. Inlaid steel (some paste plastic) guide rail, in the case of heavy load is used more. In particular, lubrication is a very important thing for it. But after the guide rail is worn, it is also very troublesome to adjust. Now the line rail is used more, but the width of the line rail is different, different machine tool design has different configuration!

硬轨胜在刚性，线轨胜在速度。

Hard track is better than rigidity, and line track is better than speed.

硬轨主要用于重切削,模具方面;线轨主要用于轻切削,产品方面.以现在市面上 普及的国产组装机而言,线轨略优于硬轨.切削的重轻也是相对的,重切削配以低转速,轻切削配以高转速,分别适配机床的硬轨或线轨,达到同样的加工要求.殊途同归!想了解更多相识，可以关注导轨丝杠

Hard rail is mainly used for heavy cutting and mold; wire rail is mainly used for light cutting and products. In terms of domestic assembly machines which are popular in the market, the price of line rail is slightly better than that of hard rail. The heavy and light cutting is also relative. Heavy cutting with low speed and light cutting with high speed are respectively suitable for hard rail or wire rail of machine tool, To achieve the same processing requirements. The same way!
