Factors that affect cnc machining accuracy of aluminum parts
As we all know, the cnc machining of precision parts is called precision machining because of its very high processing process and process requirements, and the precision of products is very high, and the machining accuracy of precision parts includes the precision of position, dimension, shape, etc. The general manager summed up the following factors:
(1) The rotary runout of the spindle of the machine tool can produce certain errors in the machining accuracy of the parts.
(2) The inaccuracy of the guide rail of the machine tool can also lead to the error of the workpiece shape of the precision parts.
(3) Transmission components can also lead to workpiece machining errors, which is also the most important factor of workpiece surface errors.
(4) Different types of tools and fixtures will also have different effects on the accuracy of the workpiece.
(5) In the process of machining and cutting, the change of the position of the force point will lead to the deformation of the system, which will result in the difference, and also make the accuracy of the workpiece produce different degrees of error.
(6) Different cutting forces can also affect the accuracy of the workpiece.
(7) The error caused by the thermal deformation of the process system. During machining, the process system will produce certain thermal deformation under the action of various heat sources.
(7) Deformation due to heating of the process system often affects the accuracy of the workpiece.
(8) Deformation caused by heating of machine tools can result in deformation of workpieces.
(9) The thermal deformation of the tool will have a great influence on the workpiece.
(10) The workpiece itself is heated and deformed, mainly by heating during cutting.
