What are the factors affecting the precision of precision parts

What are the factors that affect the precision of precision parts? As we all know, the reason why precision parts processing is called precision mechanical processing is precisely because of its high processing process and process requirements and the high precision requirements of products. The precision of precision parts processing includes the accuracy of position, size and shape, etc. We summarize the following factors that affect precision. The factors affecting the precision of dense parts processing are as follows:

(1) The inaccuracy of machine tool guideway can also lead to the error of workpiece shape in precision parts processing.

(2) The spindle rotational jump energy of machine tool produces certain errors in the processing accuracy of parts.

(3) Drive parts can also cause errors in workpiece processing, which is also the main factor of workpiece surface errors.

(4) The different types of tools and fixtures also have different effects on the accuracy of the workpiece.

(5) In the process of machining and cutting, the system will be deformed due to the change of the position of the stress point, which will lead to the difference, and also make the accuracy of the workpiece produce different degrees of error.

(6) The different cutting force will also affect the accuracy of the workpiece.

(7) The error caused by the thermal deformation of the process system. In the process of mechanical processing, the process system will produce certain thermal deformation under the action of various heat sources.

(7) Deformation caused by heating of the process system often affects the accuracy of the workpiece.

(8) Deformation caused by machine tool heating will lead to deformation of workpiece.

(9) The thermal deformation of the tool will have a great impact on the workpiece.

(10) The workpiece itself is deformed by heat, mainly in the process of cutting.
