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.

直線控制的簡易數(shù)控車床，只有兩個坐標(biāo)軸，可加工階梯軸。直線控制的數(shù)控銑床，有三個坐標(biāo)軸，可用于平面的銑削加工?，F(xiàn)代組合機床采用數(shù)控進(jìn)給伺服系統(tǒng)，驅(qū)動動力頭帶有多軸箱的軸向進(jìn)給進(jìn)行鉆鏜加工，它也可算是一種直線控制數(shù)控機床。

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.

數(shù)控鏜銑床、加工等機床，它的各個坐標(biāo)方向的進(jìn)給運動的速度能在一定范圍內(nèi)進(jìn)行調(diào)整，兼有點位和直線控制加工的功能，這類機床應(yīng)該稱為點位/直線控制的數(shù)控機床

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

導(dǎo)軌絲杠

Guide screw

普通導(dǎo)軌，也叫做硬軌，指的是導(dǎo)軌和床身是一體的鑄造件，然后在那基礎(chǔ)上加工出導(dǎo)軌，即床身上鑄造出導(dǎo)軌的形狀，再通過淬火、磨削后加工成的導(dǎo)

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

軌，也有床身和導(dǎo)軌不一定一體的，比如鑲鋼導(dǎo)軌，就是加工后釘接在床身上的。

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

數(shù)控上用的一般叫線軌，通常指滾動導(dǎo)軌，就是現(xiàn)在機床行業(yè)經(jīng)常用到的線性模組中用到的那種，我們通常稱這類元件為“直線導(dǎo)軌”，像臺灣的ABBA，日本的THK，臺灣的銀泰(PMI)、上銀(HIWIN)就專門生產(chǎn)這個。直線導(dǎo)軌本身分兩部分：滑軌和滑塊。滑塊內(nèi)有內(nèi)循環(huán)的滾珠或滾柱，滑軌的長度可以定制。它是一種模塊化的元件，是有專門廠家生產(chǎn)的標(biāo)準(zhǔn)化系列化的單獨的產(chǎn)品，可以安裝在機床上，磨損后可以拆卸下來更換。

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.

硬軌和線軌是臺灣機床業(yè)的叫法，不是標(biāo)準(zhǔn)名稱，在機械手冊上是查不到。

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.

普通機床改數(shù)控，導(dǎo)軌換不換，要看原來的導(dǎo)軌能否達(dá)到精度要求了。一般情況我覺得原來的床身根本就沒有設(shè)計安裝直線導(dǎo)軌的平面，全部安裝直線導(dǎo)軌的改造比較麻煩。一般情況下改造只是保留原來的結(jié)構(gòu)，只安裝光柵尺和相應(yīng)的數(shù)顯系統(tǒng)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.

硬軌的好還是線軌的好?

Is the hard track better or the line rail better?

加工多用直線滾動導(dǎo)軌，應(yīng)為它運動速度快，而且滾動阻力小，沒有爬行現(xiàn)象，潤滑也方便。長時間用后，精度損失較小。鑲鋼(有的貼塑)導(dǎo)軌，在重載的情況下用的較多。特別是，潤滑對它是個很重要的事情。但是導(dǎo)軌磨損后，要調(diào)整也很麻煩。現(xiàn)在是線軌的用的比較多，但線軌的寬度是有區(qū)別的機床的設(shè)計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!

硬軌勝在剛性，線軌勝在速度。

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

硬軌主要用于重切削,模具方面;線軌主要用于輕切削,產(chǎn)品方面.以現(xiàn)在市面上 普及的國產(chǎn)組裝機而言,線軌略優(yōu)于硬軌.切削的重輕也是相對的,重切削配以低轉(zhuǎn)速,輕切削配以高轉(zhuǎn)速,分別適配機床的硬軌或線軌,達(dá)到同樣的加工要求.殊途同歸!想了解更多相識，可以關(guān)注導(dǎo)軌絲杠

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!
