CNC (Computer Numerical Control) prototype model is a comprehensive computer-aided design (CAD), computer-aided manufacturing (CAM), computer numerical control (CNC) and other advanced technologies. become. After the workpiece is clamped once, the digital control system can control the machine tool to automatically select and replace the tool according to different processes, automatically change the spindle speed of the machine tool, the feed rate, the movement path of the tool relative to the workpiece, and other auxiliary functions, and complete several surfaces of the workpiece in turn. For multi-process processing, the entire processing process is automatically controlled by the program and is not affected by the operator's human factors.

CNC prototyping method: Generally, the workpiece is processed on the upper and lower sides. In special cases, the workpiece will be processed on three, four, five or six sides. In the process of processing, we will keep the gluing glue of the edge basket for the workpiece, use the edge basket to pull the bone to fix the workpiece, pour plaster to position the workpiece, and the workpiece and the CNC work surface will not have a bonding effect during processing, which is better. To ensure that the processed workpiece will not be deformed and the material level of the workpiece is accurate. In addition, gypsum is an indispensable auxiliary material in hand board processing. When turning over, the cavity surface has been hollowed out, and the wall thickness of the product is generally thin, so the thin-wall jitter phenomenon will occur during processing, which has a great impact on the appearance of the product. After filling with gypsum, it is equivalent to adding a support, which prevents thin-wall shaking during processing and ensures the processing effect.

CNC hand processing plastic materials: ABS (imported, domestic, black, flame retardant, etc.), POM (Match steel), PMMA (acrylic), PA (nylon), PC, PP, bakelite. Metal materials: aluminum alloy, magnesium alloy, zinc alloy, copper and so on.

CNC hand model advantages: fast processing speed, low cost, can achieve high processing accuracy. Moreover, the wide selection of materials can ensure the consistency of materials of handplate model and mass production parts. Hand strong sense of reality, surface quality can reach a very high level, after grinding, polishing, sandblasting, painting, screen printing, UV, electroplating and other subsequent processing, the production effect can be comparable with the mold production products, or even higher.
