cnc parts for aluminum

2019-12-13
After CNC aluminum alloy processing, the surface anodizing commonly used are: common anodizing, hard anodizing, thick film oxidation. A kind of.
The thickness of common anodizing for CNC aluminum alloy processing is 3-15um, which needs to be in place according to the product tolerance requirements; as the external dimension becomes smaller and the internal hole becomes larger after common anodizing, the aluminum surface can generate several microns to dozens of microns of oxide film. So as to improve the wear resistance, corrosion resistance and weather corrosion resistance of parts
hard oxidation of CNC aluminum alloy processing: the thickness of hard anodizing film is generally required to be 25-150um. If the accuracy of the product is very high, it is suggested that the tolerance of inner hole should be controlled within 1-3 wires, and the external dimension should be controlled within the original tolerance range. As 50% of the hard anodized oxide film penetrates the interior of aluminum alloy and 50% adheres to the surface of aluminum alloy, the hard anodized film will be produced In addition, the hardness of hard oxidation is about hv300 ~ HV500. After hard oxidation, the hardness of aluminum alloy does not change, but only the oxide film on the surface of aluminum; it also plays the role of wear resistance, corrosion resistance and weather corrosion resistance,Cnc Milling Plastic Parts, Custom Injection Plastic Parts, Cnc Turning Machining Titanium Parts,CNC Turning Titanium Parts.
thick film oxidation of CNC aluminum alloy processing: the thickness of thick film oxidation is generally required to be 50-250um. Before taking away the aluminum or aluminum alloy products, the inner hole of the products needs to be made larger by 0.5-5 wires, and the overall dimension should be made smaller by 1-5 wires within the original tolerance range. The tolerance control range should be based on the requirements of the specific products, because the oxide film of thick film oxidation increases with the time of power on, so the electric The increase of flow makes the oxide film thicken and the thick layer on the surface increase, so as to achieve the function of wear resistance, corrosion resistance and weather corrosion resistance,Cnc Turning Plastic Parts, Small Plastic Gears,OEM Custom Plastic Parts
