The method for processing cylindrical surfaces of sapphire parts, sapphire plunger pair and metering pump on its basis
- Summary
- The method of manufacturing of sapphire plunger assembly allows to achieve the level of rubbing surface roughness (working) sapphire assemblies till 3-5 angstroms, significantly reduce the coefficient of friction of the plunger assembly, which significantly affects on increasing the service life of the sapphire plunger assembly in the metering and pumping devices.
- Technology Benefits
- Increasing the service life of sapphire metering pump in 10 times guaranteed. Special chemical purity of medications, no oxides. Eco-friendly and harmless production.
- Technology Application
- The technology can be used in the manufacture of sapphire pumping and metering devices in different areas of the industry, in the filling and packaging liquid media in any ampoules, vials, syringes, and other containers. The use in the pharmaceutical, food, cosmetic, perfume, chemical and other fields of industry.
- Detailed Technology Description
- Manufacturing process takes place on the way to a landmark. From the "big" to "small." Processing diamond tool sapphire cylindrical surfaces. Rough grinding, medium grinding, fine grinding.
