The manufacturing accuracy and installation accuracy of the linear guide determine the movement accuracy of the linear motion system.
In terms of accuracy, the level of machine tools is very high among all mechanical equipment. For example, to produce seven -level precision gears, the machine must be higher than a gear level. The accuracy of the screw of the machine tool is at least higher than the eighth level. The linear guide rail has the characteristics of high rigidity and high precision, and has been widely used in precision machine tools.
Generally speaking, engineers choose the appropriate precision guide rail and installation accuracy according to the end of the exercise accuracy requirements. In the example of the machine tool above, the precision of the exercise requires the manufacturing accuracy and installation accuracy of the required guide rail.
In many factory automation projects, such as automatic feeding and leaving and truss robots, do not require such high sports accuracy. For example, some automatic feeding systems require repeat positioning accuracy of ± 0.25mm. Selecting high -precision straight -line guide also requires precise installation benchmark and high installation accuracy. This is because the manufacturing accuracy of the linear guide rail exceeds the end of the end movement accuracy.
The level of manufacturing accuracy of the linear guide is not the accuracy of the end of the end, which determines the benchmark accuracy and installation accuracy.
