Some small knowledge that affects the machining accuracy of precision parts:
As we all know, the reason why the processing of precision parts is called precision machining is precisely because its processing procedures and process requirements are very high, and the requirements for product accuracy are very high. The processing accuracy of precision parts includes the accuracy of position, size, shape, etc. The processing accuracy is the actual size, shape The conformity of the three geometric parameters of the position with the ideal geometric parameters required by the drawing. The ideal geometric parameter, for size, is the average size; For surface geometry, it means absolute circle, cylinder, plane, cone, straight line, etc; The mutual positions between surfaces are absolutely parallel, vertical, coaxial, symmetric, etc. The deviation between the actual geometric parameters and the ideal geometric parameters of a part is called machining error. We summarized the following factors that affect the machining accuracy of precision parts:
(1) The spindle rotation runout of the machine tool can produce certain errors to the machining accuracy of the parts.
(2) The inaccuracy of the guideway of the machine tool can also lead to the error of the shape of the workpiece processed by the precision parts.
(3) Different types of tools and fixtures will also have different effects on the accuracy of the workpiece.

(4) Transmission components can also lead to errors in workpiece processing, which is also the most important factor for workpiece surface errors.
(5) In the process of machining and cutting, due to the change of the position of the stress point, the system will be deformed, resulting in differences, and the accuracy of the workpiece will produce errors of varying degrees.
(6) Different cutting force will also affect the accuracy of the workpiece.
(7) Error caused by thermal deformation of the process system. During machining, the process system will produce certain thermal deformation under the action of various heat sources. The deformation of the process system caused by heating often affects the accuracy of the workpiece.
(8) The deformation of the machine tool caused by heating will lead to the deformation of the workpiece.
(9) The thermal deformation of the tool will have a great impact on the workpiece.
(10) The workpiece itself is subject to thermal deformation, mainly due to thermal deformation during cutting.
