NAICS Code 333517-04 Description (8-Digit)

Electro-Chemical Machining (Manufacturing) is a specialized process that involves the use of electrical energy to remove material from a workpiece. This process is used to create complex shapes and contours in a variety of materials, including metals, alloys, and composites. The process is highly precise and can be used to create parts with very tight tolerances. Electro-Chemical Machining (Manufacturing) is often used in the aerospace, automotive, and medical industries.

History

A concise historical narrative of NAICS Code 333517-04 covering global milestones and recent developments within the United States.

  • Electro-Chemical Machining (ECM) is a non-traditional machining process that has been used since the 1950s. The process involves the removal of metal through anodic dissolution, which is the process of dissolving metal in an electrolyte solution. The first commercial application of ECM was in the aerospace industry, where it was used to machine complex shapes in hard-to-machine materials such as titanium and nickel alloys. In the 1960s, ECM was used to machine fuel injection nozzles for diesel engines. In the 1970s, ECM was used to machine turbine blades for power generation. In recent years, ECM has been used to machine medical implants, such as hip and knee replacements, and to machine micro-features in electronic components. In the United States, ECM has been used since the 1960s. The aerospace industry was the first to adopt the technology, followed by the automotive industry in the 1970s. In the 1980s, ECM was used to machine medical implants, and in the 1990s, it was used to machine micro-features in electronic components. In recent years, ECM has been used to machine parts for the defense industry, such as missile components and aircraft engine parts. The development of new materials and the need for more precise machining has led to the continued growth of the ECM industry in the United States.
