Ten reasons leading to poor machining accuracy of precision parts




Everyone in the industry knows that the reason why precision parts processing is called precision machining is that its processing procedures and requirements are high, and the quality requirements of the parts are very high. The precision of precision parts includes position accuracy, dimensional accuracy, Shape accuracy, etc. Now Pruuni will tell you the reasons that affect the accuracy of precision parts processing.

(1) When the main rotation axis of the processing machine tool rotates, some errors will be generated to the parts, resulting in insufficient accuracy;




(2) The inaccuracy of the guide rail components of the processing machine tool can also affect the processing accuracy of the parts;




(3) The drive parts will also produce errors during the processing of the workpiece, which is also the most important factor affecting the surface error of the workpiece;




(4) Different types of tools and fixtures also have varying degrees of influence on the accuracy of the workpiece;




(5) In the process of machining and cutting, the position of the force point changes, which may cause the system to deform, which may lead to differences, and may also lead to different degrees of error in the accuracy of the workpiece;




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




(7) Errors caused by thermal deformation of the process system;




(8) The processing system is deformed due to heat, which often affects the accuracy of the workpiece;




(9) The deformation of the machine tool caused by heat will cause deformation of the workpiece;




(10) During the processing, the material will be affected by thermal deformation, which will affect the accuracy of the material.
