What are the common post-processing methods for metal CNC machining？
Add Time：2025-03-28
First.,Polish the hand board just processed from the machine, there will be some knife marks on the surface, and the edge needs to be polished with sandpaper.
Second, Spray oil According to the color requirements provided by the customer, spray a layer of paint on the surface of the hand board.
Third, Sandblasting is mainly used for handboard made of aluminum alloy material, spraying a layer of sand granular effect on the surface of the handboard.
Fourth, Oxidation is only applicable to the aluminum alloy hand plate, so that the surface of the aluminum alloy oxidizes to form a film, so that the product is not easy to scratch.
Fifth,Silk screen printing is printed on the surface of the metal hand plate with the text or pattern required by the customer
Sixth,Radium carving uses laser to knock off the paint on the surface of the hand board, and can play a variety of words, symbols and patterns, etc., with the effect of silk screen printing, but the process is the same.
Seventh,Wire drawing pulls out thin marks on the surface of the hand plate to make the texture of the metal hand plate better.
Eighth, Electroplating In order to make some details of the product more eye-catching, apply a layer of branded product color, the sample must be very smooth before electroplating. There should be no trace of impurities, and then soak in the chemical.
Nineth, Polishing The use of flexible polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece.

Tenth, Passivation Passivation can make the metal become stable, in essence, this is due to the metal surface covered with a layer of oxide film, thus improving the corrosion resistance of the metal.
