Talk about the problem importing process precision parts CNC lathe
Imports CNC lathe manufacturers tell you, in the metal processing industry, there are many companies have CNC machine tools, CNC machine tools is a technology-intensive and highly automated processing equipment electromechanical integration, is a comprehensive application of computer, automatic control, the product automatically detects and other high-tech precision machinery, CNC lathes is currently the most widely used one of CNC machine tools. CNC machining traditional processing technology produced a change. CNC lathe, the reference selection and positioning errors are issues that must be considered. Positioning reference do not coincide with the design basis of the problem still exists, but the measurement process and the reference benchmark was able to do consistent with the design basis, thereby avoiding dimensional chain solver and the error caused.
Imports CNC lathe manufacturers tell you, in the preparation of the NC programmer can be controlled using the method to determine the accuracy of the coordinates of the shape and size of each segment, and the positioning accuracy of the servo system is quite high (0.001mm above), you can easily ensure product dimensional tolerances and geometric tolerances, therefore, does not occur even if the reference or benchmark coincident non-uniform phenomenon, affecting the accuracy of the workpiece can also be controlled very small.
Imports CNC lathe manufacturers tell you, do not coincide positioning error by the reference error and reference error of two parts. Reference error when using a jig for mass production in the traditional process, the impact on the processing of parts is very prominent, but in the case of frequent use of CNC machining fixture has been rare, in part to be processed before the knife, often against the actual surface of the workpiece directly on the knife, the process is also little re-clamping or transposition, the impact of the clamp has been greatly reduced, as compared with the conventional process, the impact of NC positioning error was no longer a major factor, and this is NC one of the advantages lathe processing technology.
