As we all know, the reason why the processing of precision parts is called precision machining, precisely because its processing procedures and process requirements are very high, the precision requirements of the product is very high, and the precision of the processing of precision parts contains the accuracy of the location, size accuracy, shape accuracy, etc., summarize the following ten factors affecting the precision of precision parts processing.
(1) machine tool spindle runout can produce a certain error in the machining accuracy of the parts.
(2) the accuracy of the machine tool guide inaccuracy can also lead to precision parts machining workpiece shape error.
(3) transmission components can also lead to errors in the processing of the workpiece, which is also the most important factor in the production of the workpiece surface error.
(4) tool, fixture type will also have a different degree of impact on the accuracy of the machined workpiece.
(5) In the process of machining and cutting due to changes in the location of the force point will lead to deformation of the system, resulting in differences, which can also lead to different degrees of error in the accuracy of the workpiece.
(6) The different size of the cutting force can also cause the accuracy of the workpiece to be affected.
(7) The process system is subject to errors caused by heat deformation. During machining, the process system will produce certain heat deformation under the action of various heat sources.The deformation of the process system by heat often leads to the accuracy of the workpiece being affected.
(8) Deformation of the machine tool due to heat can lead to deformation of the workpiece.
(9) Heat deformation of the tool can have a significant effect on the workpiece.
(10) The workpiece itself is deformed by heat, mainly during the cutting process.
