Why do CNC machining quotations need 2D drawings and 3D drawings?

The quotation will be more accurate based on 2D drawings and 3D drawings, the specific reasons are as follows:

1. The tolerance size is clearly marked on the 2D file, which provides a reference for choosing the best processing method and route, so that the cost will be more accurate;

2. The surface roughness will be clearly marked on the 2D drawing. The tool selection and tool path method during processing will directly affect the surface texture effect of the product;

3. More detailed rules will be marked on the 2D drawing file, and key key dimensions will be clearly marked, so the quotation should pay more attention to whether the requirements can meet the standard;

4. The 3D drawing file can observe the structure in three dimensions, making the processing structure size clearer, and it is easier to understand the product processing requirements when quoting;

5. The drawing review during the quotation will compare 2D and 3D, so that there is no conflict, so as to facilitate efficient communication with customers.

The above are the benefits of providing 2D and 3D graphics files when quoting, hoping to make customers less detours!
