The accuracy selection of linear guide is an important link in the application of linear guide, and it is necessary to choose the appropriate accuracy grade according to the specific application scenarios and equipment requirements (usually divided into three grades: n/h/p). Let's learn more about the accurate selection of linear guide rail.
1. The concept of accuracy grade: the accuracy grade of linear guide rail refers to the comprehensive index of geometric accuracy and surface roughness of its sliding surface. The higher the accuracy level, the better the geometric accuracy and surface roughness of the sliding surface of the linear guide rail, and the higher the motion accuracy and stability.
2. Selection of accuracy grade: When selecting the accuracy grade of linear guide rail, it needs to be comprehensively considered according to the working requirements and use conditions of the equipment. Generally speaking, high-precision equipment needs to choose high-precision linear guide rails to ensure motion accuracy and stability. For some ordinary equipment, we can choose the linear guide rail with lower precision grade to meet the basic requirements of the equipment.
3. Influence of accuracy grade: the accuracy grade of linear guide rail not only affects the movement accuracy and stability of equipment, but also affects the operation efficiency and service life of equipment. High-precision linear guide rail can reduce the wear and friction of sliding surface and improve the operation efficiency and service life of equipment. However, the linear guide rail with lower precision level may lead to the increase of wear and friction of the sliding surface and reduce the operation efficiency and service life of equipment.
4. Test accuracy grade: In order to ensure that the accuracy grade of the selected linear guide meets the equipment requirements, it is necessary to test the accuracy of the linear guide. Generally, the slider can slide back and forth on the linear guide rail, and the accuracy grade of the linear guide rail can be evaluated by measuring the motion error and vibration of the slider.
In a word, when we choose the precision grade of linear guide rail, we need to consider comprehensively according to the working requirements and using conditions of the equipment, choose the appropriate precision grade and test and maintain it, so as to ensure that the performance and quality of linear guide rail meet the requirements of the equipment, improve the movement accuracy and stability of the equipment and prolong its service life.
