CNC prototype: the processing accuracy can reach ±0.05mm. The main materials for CNC processing of plastic prototypes are: ABS, PC, PMMA, PA, POM, and bakelite. Among them, ABS is the most common and commonly used plastic material, and PC and PMMA are used for processing prototypes of transparent parts. CNC-processed prototype models are characterized by fast processing speed, low cost, and can achieve high processing accuracy. Moreover, the wide range of materials can ensure the consistency between the materials of prototype models and mass-produced parts. The prototype has a strong sense of reality and the surface quality can reach a very high level. After subsequent processing such as grinding, polishing, sandblasting, spray painting, silk screen printing, UV, electroplating, etc., the production effect can be completely comparable to the products produced by the mold, so when making When making plastic prototypes, if the quantity you need to make is relatively small and the performance requirements for the prototype are relatively high, you can use CNC processing.
CNC Machining Prototype
CNC machining mainly includes CNC milling and CNC turning. According to the shape and characteristics of the parts, choose the appropriate CNC machining method.
CNC Milling
CNC milling manufactures complex geometric shapes and planes for a wide variety of products. Multi-axis metal CNC machine tools do not need to fix the mold, highly flexible, high precision. We have 3 axis, 4 axis, 5 axis machine, can meet the machining demand.
CNC Turning
CNC Turning process to produce custom cylindrical shape prototypes and end-use production part. We use CNC lathes to machine features like axial and radial holes, flat openings, grooves.
Support Material:
H&G has a wide selection of materials. The material of CNC Milling can be in various shapes. If the material is in rod or round shape, CNC turning can be selected.

1.How to do CNC business with H&G?
Please send 3D CAD data in one of the following formats (CATIA, IGS, STP, X-T), you can also send 2D drawing in PDF or AI to show us more details about tolerance and hole’s requests.
Including your requirement about material, quantity and surface finish will be much appreciated.
We will give you a quotation within 24 hours.
2.What is the difference between CNC milling and CNC turning?
Turning rotates the part against the tool. It mainly uses round bars to process parts. Milling rotates the tool against a stationary part. It mainly uses square or rectangular bars to produce components.
3.What tolerance can CNC machining achieve normally?
The tolerance of CNC milling can reach 0.025mm-0.05mm, and the tolerance of CNC turning can reach 0.02mm. These tolerances depend on the size and characteristics of the part to be evaluated. Please contact us for a more accurate assessment.
4.How to machine the internal sharp corners that cannot be machined by CNC?
We have Electrical discharge machining (EDM) service , EDM can be used to clear corners.EDM is a specialized form of CNC machining. Controlled pulses of electricity are used to erode even the hardest metals with great precision. This is essential when machining hardened tool steels. When done correctly, the surface finish is mirror-smooth and requires no secondary polishing.
5.What is the difference between machined as one piece and split & glue?
Since part features cannot be processed as one piece, we can choose the split and glue scheme.
The price of split & glue will have advantages over as one piece. If you’re in the prototype stage, or if the part doesn’t have to endure a lot of strength, split & glue is a better option.
