The process of removing material from a very high tolerance material is known a precision machining.  The tolerance depends on the particular requirement and the machinery being used. Generally, a Computer Numerical Controlled (CNC) is utilized to deliver precision machining services.

The main challenge for higher resistivity silicon material is to control the behavior of interstitial oxygen involved during the growth of Si crystals. The concentration of interstitial oxygen is generally higher than 5E17at/cc and it can be converted beneficially into oxygen precipitates below the area to eliminate metallic contaminants away from active devices.

The modern engineering ceramics sometimes require  superior production processes. Enormously strong ceramics made up of silicon nitride are manufactured by a method called reaction bonding. This process deals with forming silicon powder and then molding it in to the desired shape by heating it with nitrogen gas. 

The Silicon carbide polytype structures are considered superior than the family of different material’s structures because they exhibit least number of faults in the difference of separation in stacking series.

Even though the silicon wafer is damaged or weakened by Integrated circuit fabrication processing, high yielding IC processing is undoubtedly possible if one pays attention to wafer strength issues and furnace slip.

Sapphire is a unique material, in terms of chemical, physical and electrical properties. Sapphire can be machined using diamond processes as used in any dense alumina material. Sapphire is easy to chip than alumina. It has simple grinding techniques and procedures.

In the machining process of tantalum cemented carbide, tools with high cutting speeds is used. The tools must be kept grounded and sharp with a high positive rake. 

Donor impurities, such as phosphorus or boron for silicon, can be added to the molten intrinsic material in defined amounts to dope the crystal, therefore changing it into p-type or n-type extrinsic semiconductor.

Ceramics are inorganic non- metallic materials. Elements like nitrides, carbides, porcelain, bricks, glass and refractory resources are common examples of ceramics. In last 30 years, science has become advanced and therefore, now it is possible to transform brittle ceramics into materials by using various methods.  .

Machining of Zirconia requires same tools and design features as that of alumina ceramics. The threads, big holes etc. can be easily produced in Zirconia. 

3D Printing

Prototyping is the creation of a preliminary model or sample, enabling to test and evaluate it pre-production, making the necessary modifications.

Tungsten Carbide Recycling

In regards to scrap metal, tungsten carbide is perhaps a scrapper's best friend: it is easy to fi
