The invention discloses a guide rail electrochemical corrosion wear test method. The guide rail electrochemical corrosion wear test method comprises the following steps of acquiring at least three sets of guide rail test tables with the same configuration, wherein the test tables comprise racks, and guide rails and lead screw nut mechanisms mounted on the racks, supporting plates mounted on the guide rails, power systems used for driving, linear grating sensors used for detecting the positions of guide rail moving parts, and loading devices used for loading the supporting plates; before a test, detecting and recording the straightness of the guide rails; and during the test, carrying out intermittent spraying on the guide rails by adopting saline water with different concentrations, driving the supporting plates to move through the power systems until the set test time is up, detecting the straightness of the guide rails, performing comparison with the recorded straightness of the guide rails, and detecting the influences of the saline water with the different concentrations on the straightness of the guide rails. The method has the advantages that the electrochemical corrosion wear of the guide rails can be simulated; the influence degrees of the saline water with the different concentrations on the electrochemical corrosion wear of the guide rails can be analyzed; targeted protective measures can be conveniently formulated; and the like.
Description
technical field [0001] The invention relates to the field of test technology, in particular to a test method for electrochemical corrosion wear of guide rails. Background technique [0002] Guide rails are widely used in life and industry, especially in CNC machine tools. They provide support and guidance for CNC machine tools and are key components to ensure the effective operation of CNC machine tools. The quality characteristics of the guide rail directly affect the running performance of the CNC machine tool, and the study of the quality characteristics of the guide rail is the key to ensure the performance of the CNC machine tool. The guide rail mainly provides feed motion in the CNC machine tool, so that the moving parts reciprocate according to the given direction of the guide rail, and realize the specified functions in combination with other movements of the CNC machine tool. The application of guide rails in CNC machine tools mainly includes sliding guide rails, r...
