How does the machining accuracy of the lathe
2, the location of the tolerance: the general use of specific symbols + size tolerance to express the way.
1, size: with the size of the tolerance to represent the base system and the base system of the points, is the basic size + upper and lower deviation that.
No matter what the turning, milling, planing, boring, grinding, drilling and so on mechanical processing methods, the processing accuracy according to different specific technical requirements have different representation.
3, shape tolerance: generally with a specific symbol + digital way to represent.
