Linear Guide Positioning Accuracy Is Very High Aug 11, 2017

Linear guide, also known as rail, slide, linear guide, linear slide , For linear reciprocating occasions, with a higher than the linear bearing rated load, and can take a certain torque, can be in the case of high load to achieve high-precision linear motion.

The role of linear motion guide is used to support and guide the moving parts, according to a given direction to do reciprocating linear motion. Linear Rail Depending on the nature of the friction, the linear motion guide can be divided into sliding friction rails, rolling friction rails, elastic friction rails, fluid friction rails and other types.

Linear bearings are mainly used in the automation machinery, Linear Rail as imported from Germany, machine tools, paper bowl machine, laser welding machine, etc., of course, linear bearings and linear shaft is used as a linear guide is mainly used in the high precision requirements Mechanical structure,

Slider - Moves the movement from a curve to a straight line. The new rail system allows the machine to obtain rapid traverse speed, in the case of the same spindle speed, rapid feed is a linear guide characteristics. The linear guide, like the planar guide, has two basic elements; one is a fixed element and the other is a moving element. Since the linear guide is a standard part for the machine tool factory, Linear Rail the only thing to do is to process the parallelism of the mounting rails and the alignment rails. Of course, in order to ensure the accuracy of the machine, the bed or column a small amount of scraping research is essential, in most cases, the installation is relatively simple.

As a guide rail for the hardened steel, after grinding placed on the installation plane. Compared with the plane guide, the linear guide cross-section of the geometric shape, Linear Rail more complex than the flat guide, the reason is because the guide rails need to be processed out of the groove to facilitate the sliding element movement, groove shape and quantity, depending on the machine to complete Function. For example, a rail system that is subjected to linear forces and subjected to subversive forces is very different in design from rails that are only subjected to linear forces.

The advantages of linear guides

First, the linear guide positioning accuracy is very high, when the use of linear guide as a linear guide, because the linear guide is rolling friction rolling mode, Linear Rail the friction coefficient reduced to 1/50 of the sliding guide, dynamic friction is equal to static friction, To prevent the bed of the slip phenomenon.

Second, because the dynamic friction is almost equal to the static friction, rolling friction to wear less, and this is the machine can maintain a long time to maintain accuracy.

Third, we all know the truth of friction, because the linear guide rail friction becomes smaller, heat is not high, and can be applied to high-speed operation.

The correct choice of linear guide, is to ensure product quality of the primary choice. Of course, linear guide rail in the use of lubricating oil consumption is relatively large, Linear Rail so be sure to ensure adequate oil, so as to play the greatest role.

The linear guide can be understood as a rolling guide, which is an endless rolling cycle between the slider and the guide rail, which allows the load platform to move easily along the guide rail with high precision linearity and to reduce the coefficient of friction to the usual conventional sliding guide Cited one-fifth, can easily achieve a high positioning accuracy. Slider and rail between the end of the unit design, so that the linear guide at the same time bear the upper and lower left and right and other directions of the load.

Slider - Moves the movement from a curve to a straight line. The new rail system allows the machine to obtain rapid traverse speed, in the case of the same spindle speed, Linear Rail rapid feed is a linear guide characteristics. The linear guide, like the planar guide, has two basic elements; one is a fixed element and the other is a moving element. As the linear guide is a standard component, the machine tool factory. The only thing to do is to process the parallelism of a mounting rail and a calibration guide. Of course, in order to ensure the accuracy of the machine, the bed or column a small amount of scraping research is essential, in most cases, Linear Rail the installation is relatively simple. As a guide rail for the hardened steel, after grinding placed on the installation plane. Compared with the plane guide, the linear guide cross-section of the geometric shape, more complex than the flat guide, the reason is because the guide rails need to be processed out of the groove to facilitate the sliding element movement, groove shape and quantity, depending on the machine to complete Function. For example: a not only bear the linear force, but also to withstand the subversion of the rail system, and only bear the linear force compared to the guide. The design is very different.
