What is the effect of the loss of the linear guide

At present, we are constantly reforming and innovating the technology of the machine tool CNC industry. Whether it is the overall quality standard or the accuracy coefficient, we have made great changes, keeping up with the pace of the world, and marching toward a glorious tomorrow in the trend of the times and civilization. In today's rapid development, what is the relationship between the loss of the linear guide of the machine tool? What aspects will it affect?

 

       The function of the solid element (rail) of the linear guide system is like a bearing ring. It is mounted on a steel ball bracket and has a "v" shape. The brackets wrap around the top and both sides of the rail. To support the machine's system components, a set of linear guides usually has at least four brackets. It is mainly used to support large-scale components, and the number of brackets can exceed 4. When the components of the machine tool system are moved, the steel balls revolve in the grooves of the bracket to spread the wear of the bracket on each steel ball, which prolongs the service life of the linear guide.

 

       In order to eliminate the clearance between the bracket and the guide rail, pre-loading can improve the stability of the guide rail system and obtain the pre-loading. A steel ball of a size placed between the guide rail and the bracket. Generally, the tolerance of the diameter of the steel ball is ± 20 microns, in 0.5 micron increments. The steel ball is classified on the guide rail after screening. The size of the preloaded steel ball depends on the force on the steel ball. If the force applied to the steel ball is large and the pre-loading time is too long, it will lead to an increase in the resistance of the stent movement, which will cause the balance pollution error. In order to improve the sensitivity of the system, the pre-loading will be reduced accordingly. It's retentive, begging for a sufficient pre-addition of negative numbers, which is totally contradictory.
