As we all know, the processing of precision parts is called precision machining, precisely because its processing procedures and processes are very high, the precision of the product is very high, and the processing accuracy of precision parts includes the accuracy of position, size and shape.
The following small series of precision parts processing plant summarizes the following factors affecting the precision of precision parts processing:
(1) Inaccurate guide rail accuracy of machine tools will also lead to workpiece shape errors in precision parts processing.
(2) The spindle runout of the machine tool will produce a certain error in the machining accuracy of the parts.
(3) Transmission parts will also cause workpiece processing error, and is also the main factor of workpiece surface error.
(4) Different types of tools and fixtures will also have different effects on the accuracy of the machined workpiece.
(5) In the process of processing and cutting, due to the change of the position of the force point, the system will be deformed, resulting in differences, and the accuracy of the workpiece will also have different degrees of error.
(6) Precision parts processing different cutting forces will also affect the accuracy of the workpiece.
(7) Error caused by thermal deformation of the process system. In the process of processing, the process system will produce a certain thermal deformation under the action of various heat sources.
(8) The deformation of the process system caused by heating often affects the accuracy of the workpiece.
(9) The heat deformation of the machine tool will lead to the deformation of the workpiece.
(10) The heat deformation of the tool will have a great impact on the workpiece.
(11) The workpiece itself is heated and deformed, mainly in the cutting process.
