CNC prototype make precise 3D models via CNC machining for rapid prototyping. In this article, we’ll walk you through CNC prototyping, and our team will bring your designs to life with unparalleled quality and efficiency.
General CNC Machining & CNC Prototype Machining
CNC machining manufacturing utilizes computer-controlled automated equipment or systems to handle and process materials to create parts or products. CNC prototyping takes CAD files and feeds them into a CNC machine for prototyping and manufacturing.
Specifically, the main goal of Обработка на станках с ЧПУ manufacturing is the mass production of highly accurate and repeatable parts or products. It is commonly used in industrial production. CNC prototyping, on the other hand, focuses on smaller-scale, individualized needs. For example, to quickly produce a single or a small number of prototype samples for functional testing or user feedback. It is often used in design and development, research and experimentation.
In addition, CNC prototyping usually requires higher precision and wider adaptability. This is because it needs to meet the manufacturing and testing requirements for high-quality prototypes, including shape, size, and surface quality. Comparatively, CNC machining manufacturing can have relatively lower requirements, as it is primarily concerned with efficient and cost-effective manufacturing.
In conclusion, CNC machining manufacturing and CNC prototyping are both very important technologies in the modern manufacturing field, and they have a close connection and interaction, but there are also some differences.
