316 Stainless steel Miniature worm gear Passivation for Coffee machine.
Worm gear is a kind of gear which has one or several spiral teeth and is meshed with worm gear to form staggered shaft gear pair.
Worm gear process:
1.Rough turning, semi finishing turning and finishing turning are the most important process route for common materials.
2.Rough turning semi finishing turning rough grinding fine grinding. For ferrous materials, when the requirements of high precision and small surface roughness value and parts need to be hardened, the subsequent process can only be grinding.
3.Rough turning semi finish turning finish turning diamond turning, for non-ferrous metals, it is not easy to obtain the required surface roughness by grinding, because non-ferrous metals are generally soft and easy to block the gap between sand grains, so the final process mostly uses finish turning and diamond turning.
4.Roughing semi finishing roughing finishing finishing finishing. For the hardened parts of ferrous materials, the requirements of high precision and small surface roughness are often used.
Passivation treatment: the process of using a chromate solution and metal to form a trivalent or hexavalent chromium layer on its surface, which is called passivation, also known as chromium. It is mostly used for the treatment of aluminum, magnesium and its alloys. It can also form a chromium layer on steel, but it is rarely used alone. It is often used in conjunction with phosphating to close the pores of the phosphating layer and passivate the exposed steel in the phosphating layer. To inhibit the corrosive effect of the residual phosphating accelerator and further increase the protective ability.
Pre-treatment of pickling passivation If there is surface dirt on stainless steel workpieces before pickling passivation, they should be mechanically cleaned, and then degreasing and degreasing. If the pickling solution and passivation solution cannot be removed  Degreasing, the presence of grease on the surface will affect the quality of pickling passivation. Therefore, degreasing and degreasing cannot be omitted, and lye, emulsifier, organic solvent and steam can be used.
