What are the process standards for CNC turning and milling?

CNC turning-milling composite processing manufacturers introduced that the lathe uses the rotational movement of the workpiece and the linear or curved movement of the tool to change the shape and size of the blank, and process it to meet the requirements of the drawing.

It is more and more difficult for ordinary machine tools to meet the needs of processing precision parts. At the same time, due to the improvement of production level, the price of CNC machine tools is dropping from time to time. CNC precision parts processing mainly includes ultra-precision turning, mirror grinding and grinding.

The primary prerequisite for CNC precision parts processing is the accuracy of the process reference. The reference on the mechanical drawing is represented by a specific circled reference symbol such as capital letters A, B, C, D, etc. When the reference symbol is aligned with the surface When referring to the extension line of the surface or the size limit of the surface, it means that the surface is the reference.

When the reference symbol is aligned with the dimension line, it means that the entity centerline of the dimension is used as the reference. I mentioned for you that the precision of the craft is a more general term.

CNC turning and milling composite processing manufacturers analysis, assembly benchmarks, refer to the precision used to determine the position of parts in components or products during assembly. The measurement benchmark refers to the specification of the size and position of the processed surface to be measured when the part is inspected. The positioning datum refers to the datum used for positioning the workpiece in the machine tool or fixture during processing.

The process benchmark of CNC precision parts processing is the prerequisite to ensure the production of high-quality parts.
