Precautions for Locks Polishing
This technical article illustrates the precautions before and after polishing for make locks set.
1. The workpiece must go through the drying processing before polishing,
in order to avoid that solution is diluted by water and therefore
affect its glossiness.
2. After polishing, the workpiece should be put in at room temperature,
dry 400~500 g/l nitrate or in the 100~200 g/l Lattice inebriate solution
in a few seconds to 10 seconds to remove the surface metal. Except for
mechanical prime light and chemical polishing, it also has electrolytic
polishing. Electrochemical polishing is a process used to improve the
surface smoothness, brightness and cleanness of metal workpiece with
electrochemical method. It can improve the corrosion resistance and
light reflectivity of materials. Compared with mechanical polishing, it
also has many advantages such as high production efficiency, convenient
operation, low labor absorption degree, and easy recycling, etc. But it
cannot remove the deep scratches and other defects of workpiece, as well
as the abundant metal inclusion. With short-period service life and
difficult regeneration of electrolyte, electrolytic polishing, with high
cost, is subject to certain restrictions.
