Factors Affecting Machining Accuracy Of Precision Parts
Aug 14, 2017

As we all know, the reason why the processing of precision parts is called precision machining, it is because of its processing processes and process requirements are very high, the accuracy of the product requirements are very high, and precision machining precision parts and components include the accuracy of the location, Dimensional accuracy, shape accuracy.


(1) The spindle rotation of the machine can produce some errors in the machining accuracy of the parts.

(2) accuracy of the machine tool rail accuracy can also lead to precision parts processing the shape of the workpiece error.

(3) transmission parts can also lead to errors in the workpiece processing, which is the workpiece surface error caused by the most important factor.

(4) different types of knives, fixtures will also have a different degree of accuracy of the workpiece.

(5) in the process of cutting the process due to changes in the location of the force point will lead to deformation of the system, resulting in differences, but also make the accuracy of the workpiece to produce varying degrees of error.

(6) cutting the size of the different strength, will also lead to the workpiece accuracy affected.

(7) process system heat distortion caused by the error, mechanical processing, the process system will be under the action of a variety of heat generated a certain thermal deformation.

(7) the process system heat generated by the deformation often lead to the accuracy of the workpiece is affected.

(8) deformation of the machine will lead to deformation of the workpiece will lead to deformation.

(9) tool deformation will have a great impact on the workpiece.

(10) the workpiece itself heat deformation, mainly in the cutting process heat generated deformation.
