CNC vertical lathe Linear guides usually refer to rolling guides, and such components are often called "linear guides". The linear guide itself is divided into two parts: the slide rail and the slider. There are internally circulating balls or rollers in the slider, and the length of the slide rail can be customized. It is a modular component, a standardized serialized single product produced by a specialized manufacturer, which can be installed on the machine tool and can be disassembled and replaced after wear. Linear rails have rolling friction, fast speed, low resistance, and convenient lubrication. Now the machine tool industry uses more and more linear rails.
The hard rail refers to a casting where 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 the guide rail is processed through quenching and grinding. There are also bed and guide rails. It is not necessarily integrated. For example, the inlaid steel guide rail is nailed to the bed after processing. Linear guides usually refer to rolling guides, which are those used in linear modules often used in the machine tool industry. We usually call these types of components "linear guides". For example, THK in Japan and Shanghai Silver in Taiwan produce this .
Is the CNC vertical lathe machine good for hard rail or linear rail?
It depends on what you do. The rigid rail has good rigidity and the linear rail is fast. In general, the linear rail is better and more expensive. Linear rolling guides are mostly used in machining centers because they move fast, have low rolling resistance, have no crawling phenomenon, and are easy to lubricate. After long time use, the accuracy loss is small. Inlaid steel (some pasted with plastic) guide rails are more commonly used under heavy loads. Especially, lubrication is a very important thing for it. But after the guide rail is worn out, it is troublesome to adjust. It depends on your needs! Now the linear rail is used more, but the width of the linear rail is different, and the design of the machine tool has different configurations.
Hard rails are often used CNC Vertical lathe machine Good hard rails do not wear much, and the movement speed is not slow! Hard rails are mainly used for heavy cutting and molds; linear rails are mainly used for light cutting and products. The heavy and light cutting is also relative. Heavy cutting is equipped with low speed, and light cutting with high speed. They are respectively adapted to the hard rail or linear rail of the machine tool to meet the same processing requirements. Each has its own advantages. Hard rail wins rigidity, and linear rail wins. In speed.
