1.CNC programming
Programming is the first step in making a prototype. When engineers get the drawings, they will first review the drawings, and then program them according to the convenience of product manufacturing and whether CNC processing requires disassembly to ensure that the appearance of the product is not affected. Then, the CNC engraving and milling path is written according to the processing method, the tool type and processing speed are set according to the material characteristics, and finally the CNC engraving and milling path and speed are written according to the equipment performance.
2.CNC processing
Send the program compiled by the programmer to the CNC processing center, and the operator selects the corresponding materials and tools to process the product according to the program list.
3.Manual processing
After CNC processing, there will be a lot of burrs on the surface, which are unavoidable, so they need to be manually processed. There are also inherent defects in CNC processing, and the right-angle area cannot be fully processed in place. This also requires manual cleaning with specific tools, and then assembly and adaptation.
4.Grinding and polishing
CNC machined products will have knife marks on their surface, and the appearance of each prototype needs to be manually polished. After receiving the product, the polishing master will first check the 3D drawing, analyze the key points of the product’s appearance, and try to reflect the product’s edges, lines, gaps, etc.
5.Painting and silk-screen printing
The biggest advantage of CNC prototype is that its surface effect is closer to the final mass production effect. The product sprayed with color according to the color plate or PANTONG provided by the customer is put into the oven for baking. The baking time will vary according to the characteristics of the material and paint. After the paint is dried, UV will be sprayed. UV can not only protect and reinforce, but also beautify the paint. In addition to painting, general surface treatment also includes electroplating, silk-screen printing, laser engraving, oxidation and other methods.
6.Finished product assembly
Both the appearance prototype and the structural prototype need to be assembled. The first thing is to check whether the product accessories are complete, and then carefully assemble them according to the 3D drawings and process instructions provided by the customer. Pay special attention to the assembly relationship of the product and the gap between parts.
7.Quality inspection
All prototypes must be quality inspected before shipment. Of course, quality inspection does not mean that it is only in the last link. The quality of the prototype is mainly controlled in the previous links. This can ensure that the product is delivered on time and that customers receive satisfactory products.
