CNC prototyping is a process in which a computer numerical control machine tool excavates a whole piece according to a numbered program. CNC uses the Mastercam system, which is mainly used to control the CNC tool path. CNC milling machines are specifically used to process square and irregular objects, while lathes are used to process round objects. CNC can process some larger workpieces. It can reach 1800 * 900 * 600. Compared to SLA, SLA is relatively cheaper and can meet a wide range of prototype types. The CNC prototype model production process includes: receiving drawings → writing tool paths → transmitting tool paths to the CNC machining center → machine automation processing → manual post-processing (polishing, painting, printing, etc.)!
The industries and common applications of CNC prototype materials include digital products, household appliances, medical equipment, aviation models, automotive parts, etc. The commonly used prototype materials include plastic: ABS, PC, acrylic PMMA、 Nylon PA, POM, PP, etc; Metal materials: aluminum alloy, stainless steel, iron, copper, etc.
CNC prototype models also have many advantages. The surface treatment methods of CNC prototype models are diverse, such as grinding, spraying, painting, polishing, screen printing, electroplating, oxidation, laser engraving, bluing, UV, etc. The effect can even be compared to products produced by molds. In terms of appearance, assembly, and functional verification, it is possible to achieve the purpose of customer planning verification and create a workpiece that truly reflects the customer’s planning objectives. The CNC prototype model has moderate cost, wide processing data, and a wide range of application fields, which can meet different customers’ requirements for strength, temperature resistance, high resistance, transparency, etc.
