Eleven influencing factors of precision parts machining accuracy
by：QY Precision 2020-03-17
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 precision requirements of products are very high, the machining accuracy of precision parts includes the accuracy of position and size, with more than ten years of experience in precision parts production and processing, Shenzhen fuchengxi technology has summarized the following factors affecting the precision of precision parts processing: 1.
The spindle rotation runout of the machine tool can produce certain errors on the machining accuracy of the parts. 2.
Inaccurate precision of machine tool guide rails can also lead to errors in the shape of precision parts. 3.
Transmission parts can also cause errors in workpiece processing, which is also the most important factor in workpiece surface errors. 4.
Different types of tools and fixtures will also affect the accuracy of machined workpieces to varying degrees. 5.
In the process of machining and cutting, the system will be deformed due to the change of the position of the eaves, resulting in differences and errors in the accuracy of the workpiece to varying degrees. 6.
Different cutting forces can also affect the accuracy of the workpiece. 7.
The error caused by the thermal deformation of the process system, during the machining process, the process system will produce certain thermal deformation under the action of various heat sources. 8.
The deformation caused by the heating of the process system often affects the accuracy of the workpiece. 9.
The deformation of the machine tool caused by heating will cause deformation of the workpiece. 10.
The thermal deformation of the tool will have a great impact on the workpiece. 11.
The workpiece itself is deformed by heat, mainly due to heat deformation during cutting.
