One day, people accidentally spilled acid on the metal and found that the acid could corrode the spilled area and bite off. The bitten area and the non-bitten area formed It has a three-dimensional feeling. Then

Etching machines can be divided into chemical and electrolytic etching machines. In chemistry, chemical solutions are used to achieve the purpose of etching through chemical reactions. A chemical etching machine is a technology that removes materials by chemical reaction or physical impact.Automatic
