Six ways to distinguish the performance of linear guides
1. High guiding accuracy: The guiding accuracy refers to the linearity of the moving parts along the guide rail and the accuracy of the mutual position between the base surfaces related to it.
2. High enough rigidity: The external force of the moving parts is borne by the guide rail surface, so the guide rail should have high enough rigidity. Therefore, we often increase the width of the rail surface to reduce the specific pressure of the rail surface, and set up auxiliary rails to bear the external load.
3. The guide rail moves smoothly and lightly: when the linear guide works, it should be light and labor-saving, the speed should be uniform, and there should be no crawling phenomenon at low speed.
Fourth, the structure of the guide rail is good: on the premise of ensuring the other requirements of the guide rail, the guide rail structure should be simple to facilitate processing, measurement, assembly and adjustment to reduce costs. The guide rails used by different equipment must be specifically analyzed and corresponding design requirements must be put forward.
5. Good wear resistance: The wear resistance of the guide rail means that the guide rail can still maintain a certain degree of accuracy after long-term use. The guide rail will wear out during use, but the amount of wear should be small, and it can be automatically compensated or adjusted easily after wear.
6. High adaptability to temperature changes: Linear guides should be able to work normally under the conditions of operating temperature changes.
