The reason why precision parts processing is called precision processing is that its processing procedures and processing requirements are very high, and the precision requirements of products are also very high, and the processing accuracy of precision parts includes: Position accuracy. Dimensional accuracy, shape accuracy, etc., based on the company’s more than ten years of production and processing experience, the technicians of Yamei Precision summarized the following factors that affect the accuracy of precision parts:
(1) The rotation of the spindle of the machine tool will bring certain errors to the machining accuracy of the parts.
(2) The inaccuracy of the machine tool’s guide rail will also cause errors in the shape of precision parts.
(3) The transmission component will also cause errors in the processing of the workpiece, which is also the most important factor causing the surface error of the workpiece.
(4) Different types of tools and fixtures will also have varying degrees of impact on the accuracy of the workpiece.
(5) During the processing and cutting of precision parts, the system will be deformed due to the change of the position of the force point, which will cause differences and also cause different degrees of errors in the processing.
(6) Different cutting forces will also affect the accuracy of the workpiece.
(7) Errors caused by thermal deformation of the process system. In the machining process, the process system will produce certain thermal deformation under the action of various heat sources.
(8) The deformation of the processing system caused by heating often affects the accuracy of the workpiece.
(9) The deformation of the machine tool during heating will cause the workpiece to deform.
(10) The thermal deformation of the tool will have a great impact on the workpiece.
(11) The workpiece itself processed by precision parts is deformed by heat, which is mainly caused by the heat in the cutting process
