Technical Field
[0001] The utility model relates to the technical field of linear guide rails, in particular to a machine tool linear guide rail with a lubrication structure. Background Art
[0002] Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving parts to perform reciprocating linear motion in a given direction. Depending on the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types. Linear guides are widely used on linear motion bodies in automation equipment and precision machinery.

If it is not eliminated in time, it is easy to cause high oil temperature, increase the degree of damage to the balls, and easily affect the normal operation of the guide rails. Utility Model Content
