CNC prototype means prototype manchined by CNC machinery, which achieve wanted
result of product sample after late surface treatment. Because of high accuracy of CNC prototype,
it occupies half position of prototype industry. Although CNC prototype is very common,
many customers think that it is high price. Actually it dosen’t. Many saleman quote after
looking at 3D drawing. If the 3D drawing includes the elements below, the manchined
difficulty will increase and the price will higher.
1. The accuracy and surface roughnessof the part needed to be processed: if the tolerenece
of part requires ± 0.01mm, which is high requirement to both machining equipment and
technician, the price will be relatively high.
2. The structure and dimension of the part needed to be processed: If the structure
of product is complicate, so the cost will be higher than simple one.
If the whole dimension of product is big and appearance is curved surface shape,
the cost also higher.
3. The part needed to be processed is difficult-to-machine material, such as stainless steel.
The hardness of material is big, which need the tungsten steel tool.
So the cost will higher than common mnaterial.
4. The technology of prototype is much more including CNC machining, polishing,
sprying, silk-screen, brushing, watermark, plating, carving.
All in all, the precision, dimension, complexity, material and technological
process will inflence the price of CNC prototype.
