Methods to improve the quality of mold parts processing
Mold parts processing of die steel material hardness, mold processing equipment required to have thermal stability, high reliability.
For complex cavity and multifunctional composite mould, as parts of complicated shape, must improve the level of mould design and manufacture of a variety of groove, a variety of material in a mold forming or assemble components of multifunctional composite mould, requires large amount of processing programming procedures, has profound hole cavity composite cutting ability and high stability, improve the processing difficulty.
Machining quality of mold parts includes machining accuracy and surface quality: machining accuracy is the degree of conformity of three kinds of geometrical parameters of the actual size, shape and position of the machined part surface with the ideal geometrical parameters required by the drawings;The deviation value of actual and ideal geometrical parameters of the part is called machining error.
Machining accuracy and machining error are terms used to evaluate geometrical parameters of machined surfaces.The machining accuracy is measured by the tolerance grade.Machining error is represented by numerical value. The larger the numerical value, the larger the error.High machining accuracy means small machining error and vice versa.The actual parameters obtained by any machining method are not absolutely accurate. From the function of the part, as long as the machining error is within the tolerance range required by the part drawing, the machining accuracy is guaranteed.
The quality of the machine depends on the machining quality of the part and the assembly quality of the machine. The machining quality of the part includes the machining accuracy of the part and the surface quality.The difference between them is called machining error.The machining error reflects the machining accuracy.The higher the error, the lower the machining accuracy, the higher the error.Main factors affecting machining accuracy: dimensional accuracy, the degree of conformity between the actual size of the machined part and the tolerance center of the part size.
