Linear rail or hard rail, suitable is the most important
Jun 25, 2018

The hard rails refer to the castings where the rails and the bed are integrated, and then the rails are machined on the basis of the castings. That is, the shape of the rail is cast on the bed, and then the rail is processed after quenching and grinding. There are also beds and guide rails that are not necessarily integrated, such as inlaid steel rails, which are attached to the bed after processing. Linear rail usually refer to rolling guides. The linear guide rail is divided into two parts: the slide rail and the slider. Inside the slider there are internal circulating balls or rollers. The length of the slide can be customized.

The main difference between the two is that the hard guide rail can withstand large cutting force and is mainly used for machine tools over 1.3 meters, which are mainly used for mold processing.

The disadvantage is that the guide rail cannot move too fast.

The linear guide rail bears relatively small cutting force, but the guide rail moves quickly, which is mainly used in some small machine tools. For service life, linear guide is much higher than rigid guide.

The sliding contact surface of hard rail is large, with good rigidity, strong anti-seismic capability and strong load bearing capacity. It is suitable for heavy load cutting. Because of the large contact area of the guide rail, the machine tool runs more smoothly, which is suitable for machine tools with higher vibration requirements, such as grinding machines.

The maintenance of the rail is of Paramount importance. If the track is not sufficiently lubricated, it will cause burning of the track or abrasion transition, which are fatal to the precision of the machine tool.

Therefore, as a whole, the application of hard rail is suitable for heavy cutting, large mould, high hardness workpiece, and general precision workpiece.

The assembly of wire and rail is simple, and high quality assembly can be completed with a little training.

The cutting force of the wire rail is less than that of the hard rail. Fushengjin has greatly improved its carrying capacity through some structural designs.

Rail line is suitable for high speed machine, high speed cutting, suitable for processing products, small precision molds, running speed, high precision, low maintenance cost, and is more than hard rails are its advantages.

And the line rail is not perfect, it is not as stable and rigid as the hard rail, and the transportation and processing environment requirements are higher.

To sum up, when choosing the processing center, we should choose the suitable products according to our own needs and conditions, so as to achieve the ideal processing effect.
