How to use the linear guides for cnc?

Ordinary linear guides for cnc, there seems to be a hard track, which refers to the casting of the guide rail and the bed body, and then on the basis of the linear guides for cnc, that is, the shape of the rail cast on the bed, and then through The linear guides for cnc, which are processed after quenching and grinding, also have a bed and a guide rail that are not integrated, such as a steel guide rail, which is nailed to the bed after processing.

The general purpose of the numerical control is called the rolling rail, which is usually used in the linear module which is often used in the machine tool industry. We usually call this kind of component "linear guides for cnc", like THK of Japan. Taiwan's Intime (AMT),SG (HIWIN),CHINA (ZYSL) specialize in the production of this linear guides for cnc. The linear guides for cnc itself is divided into two parts: the slide rails and the slider. The slider has internal circulating balls or rollers, and the length of the rail can be customized. It is a modular component and is a standardized series of individual products produced by a special manufacturer. It can be mounted on a machine tool and can be removed and replaced after wear.

Hard rails and rails are the name of Taiwan's machine tool industry. They are not standard names and cannot be found in the mechanical manual.
Ordinary machine tools change to CNC, the rails can not be changed, depending on whether the original linear guides for cnc can meet the accuracy requirements. In general, I feel that the original bed has no plane to design and install linear guides. It is more troublesome to modify the linear guides. In general, the transformation only retains the original structure, only the grating scale and the corresponding digital display system.

Is the hard track good or the line track good?
The machining center often uses linear rolling guides, which should have a fast moving speed, low rolling resistance, no creeping phenomenon, and convenient lubrication. After a long time of use, the loss of precision is small. Inlaid steel (some plastic) guide rails are used in heavy load situations. In particular, lubrication is a very important thing for it. However, after the linear guides for cnc wear out, it is very troublesome to adjust.

Nowadays, there are more wires used, but the width of the track is different. The design of the machine has different configurations! But the high-end machine uses hard tracks is still more!

Guide ... This situation can not be so sure! High-end imported machines use hard tracks or more. The domestically produced formal brand processing centers use a lot of hard tracks. Good hard track wear is still not big, and the speed of movement is not slow! It’s not so certain that each of them has published this situation! High-end imported machines use hard tracks or more. The domestically produced formal brand processing centers use a lot of hard tracks. Good hard track wear is still not big, and the speed of movement is not slow!

Hard tracks win in rigidity, linear guides for cnc wins at speed.
In general, the hard track is good, the life of linear guides for cnc is not long.
Hard rails are mainly used for heavy cutting and moulding; wire rails are mainly used for light cutting and products. In terms of the most popular domestic assembly machines on the market, linear guides for cnc are slightly better than hard rails. It is also relative, heavy cutting with low speed, light cutting with high speed, respectively adapt to the hard track or line rail of the machine, to achieve the same processing requirements.
