Introduction of linear guides on sliding guides

The sliding guide material is: the guide rail is a hardened steel, which is finely ground and placed on the mounting plane. Compared with the planar guide rail, the geometry of the cross section of the linear guide is more complicated than that of the flat guide. The reason for the complexity is that the groove needs to be machined on the guide rail to facilitate the movement of the sliding element. The shape and number of the groove depend on the machine tool to be completed. The function.


       Did you know about the linear guides about sliding guides? Then Ang will continue to work hard to teach you some expertise on the guide rails. Today we talk about the introduction of linear guides on sliding guides.


       The development of the traditional guide rails, the primary one is the sliding element and the guide rail. The sliding guide rail is characterized by the use of medium between the guide rail and the sliding member. The difference is in the selection of different media.


       Hydraulics are widely used in many rail systems. The hydrostatic guide rail is a kind among them. Under the pressure effect, the hydraulic oil enters the groove of the sliding component, and forms an oil film between the guide rail and the sliding component to separate the guide rail and the moving component, thereby greatly reducing the frictional force of the moving component. The hydrostatic guide rail is extremely useful for large loads and has a compensatory effect on the bias load. For example, when a large sand box is processed, it happens to go to the end of the machine stroke, and the load rail can increase the oil pressure, so that the guide rail accurately maintains the horizontal load condition. Some horizontal boring and milling machines use this skill to compensate for the reduction in spindle speed during deep hole machining.


       Another type of rail that uses oil as a medium is a dynamic pressure rail. The difference between the dynamic pressure rail and the static pressure rail is that the oil does not act under pressure. It uses the viscosity of the oil to prevent movement between the moving element and the guide rail. The direct touch, the strength is to save the hydraulic pump.


       After the introduction of the CPC linear guides on the sliding guides, we must have further deepened the linear guides, which is also helpful for the use of guide rails.
