CNC Prototype Machining is a fast and precise method for creating functional prototypes directly from CAD models. Using Computer Numerical Control (CNC) equipment, it enables the production of high-accuracy parts in a wide range of metals and plastics.
Rapid CNC Machining refers to quick-turn CNC manufacturing that delivers prototypes or low-volume production parts in just a few days. It’s ideal for product development, design verification, and engineering testing.
Key Benefits:
Fast Turnaround: Parts delivered in as fast as 1–3 days.
High Precision: Tight tolerances up to ±0.01 mm.
Material Flexibility: Aluminum, steel, ABS, POM, and more.
Functional Prototypes: Machined parts can be used for real-world testing.
Applications:
Product development
Engineering evaluation
Functional fit and assembly tests
Bridge production before mass manufacturing
When using CNC for prototyping, CNC machining methods can be used to program and analyze 3D data. Qualified samples can be made directly using materials such as ABS, PMMA and nylon.
CNC prototypes can quickly produce samples with ideal surface quality, especially for large products.
After surface spraying, screen printing, and electroplating, prototypes made using CNC prototypes are more attractive than prototypes made with molds.
CNC prototypes will become the mainstream of rapid prototyping.
CNC prototype plastic material:
ABS (imported, domestic, black, flame retardant), polyoxymethylene (POM), PMMA (acrylic), PA (nylon), PC, PP and bakelite. Metal materials: aluminum alloy, magnesium alloy, zinc alloy, copper, etc.
Advantages of CNC prototyping:
The advantages of CNC prototypes include high machining speed, low cost and high machining accuracy.
A wide selection of materials ensures consistency in materials used for prototyping and mass production. Prototypes made with CNC are closer to real molds and have higher surface quality.
After grinding, polishing, sandblasting, painting, screen printing, UV and electroplating, the prototypes and molds made using CNC are completely comparable or even better.
