Description

Technical Field

[0001] The utility model relates to the field of linear guide rail processing, in particular to a clamping mechanism for linear guide rail processing. 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. When processing linear guides, the raw materials must first be cut and cut to obtain rough materials, and then rough processing is required. The linear guide is placed on a grinder for rough grinding, and then placed on a milling machine for processing. After fine grinding on the grinder, it is finally quenched to reach the finished product.
