We all know that the processing of precision parts is called precision mechanical processing (CNC processing), which is precisely because of its high processing process and process requirements, and the accuracy requirements of the product are very high. The processing accuracy of precision parts includes the accuracy of the location accuracy , Size accuracy, shape, etc. The following factors affect the processing accuracy of CNC processing precision parts:
1) There is a certain error in the processing accuracy of the workpiece.
(2) The precision of the machine tool guide is not high, which will also cause the shape error of the workpiece during the processing of precision parts.
(3) The transmission parts may also cause workpiece processing errors, which is the main factor that causes the surface error of the workpiece.
(4) Different types of knives and fixtures will also have to varying degrees of impact on the processing accuracy of workpieces.
(5) During the cutting process, due to changes in the position point position, the system will deform, which will cause differences, and there are different degrees of errors in the accuracy of the workpiece.
(6) Inconsistent cutting force will also affect the accuracy of the workpiece.
(7) The error caused by the process system due to thermal deformation. During the processing, under the influence of various thermal sources, the process system will produce a certain heat deformation.
(7) Deformation caused by heating process systems often affects the accuracy of workpieces.
(8) The high temperature deformation of the machine tool will deform the workpiece.
(9) The thermal deformation of the tool has a great impact on the workpiece.
(10) The workpiece itself is heated and deformed, mainly due to heating during cutting
