Introduction of CNC machining accuracy

In the process of machining precision mechanical parts, there are the following points to control the machining accuracy: geometric accuracy: geometric accuracy refers to the accuracy of the geometric shape of each surface or axis of the component, such as whether the line is straight, whether the surface is flat, whether the normal section on the cylinder is round, etc. The smaller the number of geometric tolerance is, the higher the shape accuracy is; Dimensional accuracy: dimensional accuracy refers to the accuracy of the size of parts after processing, expressed by “dimensional tolerance”. When the dimensions of parts are the same, the higher the accuracy is, the smaller the tolerance number is; Position accuracy: position accuracy refers to the accuracy of the mutual position between the surfaces of components, such as whether the two planes are parallel, vertical, and whether the two axes are coaxial, which is expressed by “position tolerance”. Hold these points, precision machining accuracy of mechanical parts is easier to control.

The above is the processing precision of precision mechanical parts, thank you for sharing!
