Description

Technical Field

[0001] The present invention relates to the technical field of a non-electric variable regulating system, and in particular to a linear guide rail grinding machining precision regulating system and method. Background Art

[0002] Linear guides are also called line rails, slide rails, linear guides, and linear slides. They can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. The function of linear guide motion is 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 mainly used in mechanical structures with relatively high precision requirements. Instead of an intermediate medium, rolling steel balls are used between the moving elements and fixed elements of the linear guides. Among them, grinding is required in the production and manufacturing process of linear guides to improve the surface accuracy of the linear guides. However, the existing linear guide grinding process requires manual intervention to adjust the grinding feed parameters of the linear guides, and requires manual adjustment of the grinding feed error of the linear guides, which reduces the efficiency and quality of linear guide production and manufacturing.
