The CNC prototype refers to the prototype processed by CNC machining. Due to the high precision of CNC prototype, it still occupies half of the prototype industry.Although CNC prototype are common, But many users think the price is too high. In fact, it is not -- thetechnical engineerare quoted after checking the 3D drawings. The difficulty will increase and the price will naturally be higher If the following factors appear in the 3D drawings.

1.Precision and surface roughness of processed parts:If the tolerance of 0.01mm is required, both the machine or technical master also have high requirements, Accordingly the cost will be raising.

2.The structure and size of the processed part: The cost will be much higher if the product structure is complicated, the processing cost will rise a lot if the overall size of the product is large or the appearance is a curved surface shape.

3.If the part material is stainless steel,Material is hardness, Need to use tungsten steel with a hard tool, and computer gongs need to be Taiwan or Japan machine with to do, Of course, the cost will be higher than processing with ordinary materials.

4.There are many post-processing technologies for prototype.Such as polishing, spray paint, silk screening, wire drawing, electroplating, laser carving, etc. The more post-treatment processes used, the higher the price.

In conclusion, the accuracy, size, complexity, material and technological process of CNC prototype are all factors affecting the price of prototype.
