Precise machining using chemical etching process.

Precise machining involves the production of extremely complicated metal parts made mainly of thin sheets. In addition to accurate metal parts, they are often used for specific purposes. However, there are different techniques, such as chemical engraving, metal stamping and RF shielding to produce accurate metal parts.

The chemical etching process is mainly used to produce precise metal parts. The machine system offers great flexibility for the production of precise metal parts, with an unusual configuration, as well as metals with a tight tolerance of 0.0005 “. In addition to chemical engraving machines, they are capable of producing small holes and screws that are not possible in most stamping processes. The chemical engraving machine uses state-of-the-art CAD software, with a resolution of ¼ million in the production process, which facilitates fast and low-cost operations. the prototype and to produce large quantities of precision metal parts… an important role in supporting NASA’s research system.

Likewise, the metal stamping machining process, also known as progressive stamping, or long-term metal stamping, is widely used in the production of precision metal parts with a thickness of 0.002 “to 0.135”. The technique is mainly used to process low-cost parts that have three dimensions.

RF protection machining allows the processing of precise metal parts, such as RF shields. The machine assists in the production of custom and standard RF shields. The machine is capable of manufacturing product parts from a simple five-sided box, to a complex shield of several cavities with removable covers. In addition to the machining process, it facilitates the production of removable flat, molded and upholstered covers, with or without logos and part numbers. In addition, standard RF shields are available in 54 dimensions and are provided with a prototype, which allows the operator to flexibly design custom RF shields.

Precise machining is used in various materials, such as steel, bronze, graphite, plastic, glass and so on. The tools are used depending on the size of the project and the materials that can be used. As in the aerospace industry, high-speed machining can be used, while in the wood industry it may be possible to use photochemical engraving and grinding processes. The precision and quality that manufacturing needs bring to manufacturing requires that those involved in design and manufacturing understand the industry and the processes accepted by the industry.

Advances in precision machinery have given the aeronautical industry a great boost, as aircraft need parts designed with maximum perfection. Precise machining has made it possible to manufacture improved hospital tools, also serving a social cause.

Chemicals used in Jewelry making.

Jewelry enhances one’s beauty; chemicals enhance the beauty of the jewelry.

To enhance one’s beauty, the use of jewelry is widespread. Sometimes the economic aspect of an individual is reflected by the kind jewelry one wears. The use of jewelry is common in women, but men also use articles of jewelry to a greater extent. Not even in modern times, the use of jewelry is very common from ancient times. Historical evidence shows the extent of usage of jewelry in ancient times. In ancient Egypt, the poor farmers, as well as kings and queens, were also very fond of jewelry. In the Indian subcontinent, The Hindu gods and goddesses even imagined wearing jewelry.

As time passed, the standards of jewelry have changed. The metals like gold silver platinum etc. and the gems like diamond, Ruby, etc. are the same, but the types of modifications on these have changed from time to time. Even for a single metal or stone, we have many types of modifications available that represent the same article in different forms. Several chemicals and chemical techniques also used for that.

Various chemicals used in jewelry making are:

• Sulfuric acid

The metal surface contains many types of impurities, which may sometimes affect in various processes. So, to clean the metal surface, strong acid such as sulfuric acid is used. Sulphuric acid is highly reactive and generally used while pickling silver.

• Boric acid

Jewelers use Boric acid powder mixed with denatured alcohol in a glass alcohol cup to prevent oxidation of sterling silver during soldering.

• Saltpeter

It is commonly known as potassium nitrate, which used as an oxidant in jewelry making.

• Nitric acid

Nitric acid is when mixed with hydrochloric acid; it is called aqua regia. It mainly used to check whether the gold is real or a fake one.

• Borax

Borax and water are a flow flux used by jewelers. But it leaves a glassy coating on the jewelry, which is difficult to remove.

Apart from various chemicals, some chemical methods are also in the making of jewelry. A typical example is chemical etching. Chemical etching is a process of using baths of temperature-regulated etching chemicals to remove material to create an object with the desired shape. It is a very complex process, but it is of very much utility. In modern times this method is being very impactful in enhancing the look of the jewelry.
