Knowledge: Manufacturing process of Metal hardware prototype Model
In general, the hardware prototype model is produced by cnc. The processing flow of the CNC machine tool includes several steps such as design drawing, programming, cnc processing, grinding, assembly, oil injection, oxidation, carving, electroplating and the like. Smile RP LTD today gives you a breakdown of the specific operations of the hardware prototype model manufacturing process steps.
Design drawings: The prototype drawings are generally used by the professional designer by AUTOCAD, and the format of the prototype drawings is mainly. IGS/. STP/. STL/. PRT/. X-T, etc.
Programming: The programmer disassembles the drawing and analyzes the 3D data and then writes the program language to control the NC machining center.
Cnc machining: input programming into CNC NC machine tool, execute program command, CNC NC machine tool according to the path set by the program, remove the surplus part from the hardware material, thus get the prototype of the hardware prototype model.
Grinding: after the hardware plate model is processed by the CNC numerical control machine tool, the surface layer of the model will inevitably have a lot of rough edges and knife marks, so it is necessary to deal with these problems manually, for example, by polishing and plastering.
Line polishing, or grinding with sand paper, first of all with very thick sand paper for rough processing, remove the surface of the very thick burr and then fine lines of grinding.
Oxidation: oxidizes the surface of the metal plate, forming an oxide film, and can oxidize a variety of colors according to customer requirements, so that the product is not easy to scratch flowers.
Plating: need to be polished before plating very smooth, can not have any trace of impurities, and then put into the chemical potion immersion, there are gold, silver, bronze, etc., this is divided into ferry and vacuum crossing.
Laser carving: use laser to remove the paint on the surface of the product to make part of the position transparent.
Assembly: It is to assemble each part of the hardware prototype model, and after the processing, it is the data detection of the assembly problem.
Through the previous understanding, I believe we have a certain understanding of the operation of the hardware plate model production process.
