As we all know, the processing of precision parts is called precision machining, precisely because its processing procedures and processes require very high requirements on the accuracy of products, and the precision of precision parts includes the accuracy of position. Dimensional accuracy, shape accuracy, etc. The general manager of Chengyu Precision Machinery combined with the company's more than ten years of production and processing experience summarized the following factors that affect the precision of precision parts processing:

  (1) The machine's main shaft rotation runout can cause a certain error in the machining accuracy of the part.

  (2) The inaccuracy of the machine tool guide can also lead to errors in the shape of workpieces for precision parts.

  (3) Transmission components can also cause errors in workpiece machining, which is also the most important factor in producing surface errors on workpieces.

  (4) The different types of tools and fixtures will also affect the accuracy of the workpiece.

  (5) In the process of machining and cutting, due to the change of the position of the force point, the system will be deformed, which will cause differences, and it will also cause the accuracy of the workpiece to have different degrees of error.

  (6) Different cutting forces will also affect the accuracy of the workpiece.

  (7) The error caused by thermal deformation of the process system. During the machining process, the process system will generate certain thermal deformation under the action of various heat sources.

  (8) The deformation of the process system due to heat will often affect the accuracy of the workpiece.

  (9) Deformation of the machine due to heat 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, which is mainly caused by heat during the cutting process.
