History

A concise historical narrative of NAICS Code 333612-01 covering global milestones and recent developments within the United States.

  • The manufacturing of gears and gear cutting has been around for centuries, with the earliest known gears dating back to ancient Greece. However, it wasn't until the Industrial Revolution that the industry began to take off. In the late 1700s, the first gear-cutting machine was invented, which allowed for the mass production of gears. In the 1800s, advancements in metallurgy led to the development of stronger and more durable gears, which were used in the growing railroad industry. In the 1900s, the industry continued to grow and expand, with gears being used in a wide range of applications, from automobiles to airplanes. In recent history, the gears and gear cutting industry in the United States has faced challenges due to increased competition from overseas manufacturers. However, the industry has also seen advancements in technology, such as the use of computer-aided design and manufacturing (CAD/CAM) systems, which have improved efficiency and accuracy. Additionally, the industry has adapted to changing market demands, with a growing focus on producing custom gears for specialized applications. Overall, the gears and gear cutting industry has a rich history of innovation and adaptation, and continues to play a vital role in modern manufacturing.
