數控銑床上面經常會用到線軌和硬軌，而這兩個咋一聽的話，可能很難區分一二。少一般情況下，外行很難將其徹底區分開來。其實可以簡單來說，線軌就是一種用于直線往復來回運動的東西，它的作用就是在承受重量或者沒有負載的情況下，能夠穩定的保持良好的直線運動，使得機床的工作能夠趨于穩定和精準。要是硬要將線軌和硬軌進行詳細區分的話，那就要從兩者在應用和作用方面的不同，進行比較。

Wire rails and hard rails are often used on CNC milling machines, and it may be difficult to distinguish between them at first glance. At least in general, it is difficult for laypeople to completely distinguish it. In fact, it can be simply put that a track is something used for linear reciprocating motion. Its function is to maintain good linear motion stably under weight or without load, making the work of the machine tool more stable and accurate. If it is necessary to distinguish between track and hard track in detail, then it is necessary to compare them based on their differences in application and function.

1、應用上面

1. On the application side

線軌和硬軌究竟有什么不同

What are the differences between track and hard track

線軌其實主要是使用在自動化機械上，比如常見的機床、折彎機、激光焊接機，這些上面用的對一些，而且不管是否承受負載的情況下，或者是否有扭矩影響的情況下，都能夠確保穩定和精準的做著直線運動。

Line tracks are actually mainly used in automated machinery, such as common machine tools, bending machines, and laser welding machines. These machines are suitable for certain purposes, and can ensure stable and accurate linear motion regardless of whether they are under load or torque influence.

硬軌的話，一般多用在一些小小的額模具中，或者是一些小型零件的加工上面。但一般使用硬軌的話，都要配有主軸冷卻系統。

Hard rails are generally used in small molds or in the processing of small parts. But generally, if a hard rail is used, it needs to be equipped with a spindle cooling system.

2、作用上面

2. In terms of function

線軌其實是一種支撐和引導運動部件，可以按照既定設好的方向，做著來回的直線運動。

A track is actually a supporting and guiding component that can move back and forth in a straight line according to a predetermined direction.

硬軌的話，一般會配有刀庫，需要定時自動更換刀片，一般它是實現水平運動的一種。

If it is a hard track, it is usually equipped with a tool magazine, which needs to automatically replace the blades on a regular basis. Generally, it is a way to achieve horizontal movement.

其實在行業人士的眼里，線軌和硬軌的區別是一目了然的。只是一般多數人不太了解這行的話，可能會與一點點懵。簡單來說的話，就是線軌就是直線運動工作，而硬軌是水平運動工作。

In fact, in the eyes of industry professionals, the difference between rail and hard rail is clear at a glance. However, if most people are not familiar with this field, they may feel a little confused. Simply put, the line track works in linear motion, while the hard track works in horizontal motion.
