There are 2 main reasons in CNC machining process which will damage your CUSTOM CNC MACHINING PARTS:
1. Machining Processes
Machining custom cnc parts will produce metal peel when cnc turning or cnc milling, If not cleaned in time, metal shavings will scratch the surface. thereby reducing the surface quality of the product. Although this does not affect the measure of the product. Also from this, we can see the difference in China cnc service.
Our production staff will regularly clean shavings according to products materials. The cleaning frequency of aluminum machining parts will be higher than that of steel products. The shavings of cnc copper part is like crushing. It is more convenient to clean.
At the same time. In the process of clamping and removing the product from cnc lathe or cnc milling machine, our operators will also take care not to scratch the surface of the product.
2. Transportion Processes
It is easy to demage machined parts, especially for aluminum machining. Copper machined products need to do surface treatment when we complete cnc processing. Such as sandblasting, plating, aluminum anodizing … copper polishing, gold plating and silver plating.
Aluminum and copper are same soft materials. Without well protection, they can collide easily during operation, and bring damage to the surface. So it will greatly reduce the quality of the product.
We will respond according to the quantity and different products. For large-volume cnc machined parts, we will choose special protection materials. Such as blister boxes and plastic trays. So that the products can be well protected from the processing area to the surface treatment area. Greatly reduces the chance of damaing the product surface.
Small number of CNC turning or cnc milling parts are relatively simple. To avoid collision, we will use homemade cardboard or bubble film to separate the products.

Does It increase the cost of cnc machined components in production process?
Yes, For sure, it will increases the cost of CNC MACHINING production, but It can help you to retain customers and improve the quality level of CNC MACHINING FACTORY. In addition, the same model can be shared for other CNC TURNING PARTS, so It does not add much cost to all CNC CUSTOM CNC MACHINING PARTS.
Finally, If you would like to know more about how to protect your custom cnc machining service during the production process, please contact us and we will give your a perfect solution and manageable cost.
