The so-called hard rail is the traditional machine tool guide rail, which is usually a guide rail made of cast iron or steel after quenching and grinding. The bed and the guide rail are not necessarily integrated. For example, the steel guide rail is nailed to the bed after the guide rail is processed. We call it the hard track.
Linear rails usually refer to rolling guide rails. Among them, hard rails and linear rails such as linear ball guide rails, linear roller guide rails, and needle roller guide rails are the names of Taiwan's machine tool industry, not standard names.
Hard rails are common metal-to-metal rails, including wire rails. Corresponding to it is the soft rail, usually refers to the plastic rail pair. Linear guides generally refer to ball linear guides.
The linear rail means that the guide rail is assembled to the bed, and the hard rail means that the guide rail and the bed body are integrated castings and then the guide rail is processed.
The linear rail is a ball bearing and a guide rail, and the speed is fast. The hard rail is slower, more rigid, and crash-resistant.
Today's high-speed machining centers generally use linear rails.
The advantages of the two processing centers are as follows:
The rigidity of the hard rail is good, the speed of the wire gauge is fast, in general, the hard rail is good but the price is more expensive, but at present, the wire rail is used more in China, but the width of the wire rail is different. The design of the machine tool is different. There are different configurations! The machine uses hard track is more!
The life of the wire rail is not as long as the hard rail. The hard rail is mainly used for heavy cutting and molds; the wire rail is mainly used for light cutting and products. As for the domestic assembly machines that are popular on the market today, the price of the wire rail is superior to the hard one. Large rail processing center.
The light weight of the cutting is also relative. The heavy cutting is matched with the low speed and the light cutting is matched with the high speed. They are respectively adapted to the hard rail or the linear rail of the machine tool to achieve the same processing requirements. Faced with different processing needs, choosing the right processing center is conducive to ensuring the quality of the product and to protecting the processing center.
