About machine-tools; gear cutting, gear grinding or gear finishing machines, working by removing metal, sintered metal carbides or cermets

hs code 846140 covers a critical segment of the metalworking machinery industry, which plays a vital role in the broader manufacturing sector. These specialized machine tools are used to produce and refine gears, a fundamental component in a wide range of mechanical systems and devices. From automotive transmissions to industrial equipment, the output of this industry supports the efficient operation of countless products that drive economic activity across multiple industries.

Production process

The production of gear cutting, grinding, and finishing machines involves several key processes. First, the machine frame and components are fabricated using advanced metalworking techniques like casting, welding, and machining. The gear-shaping mechanisms, such as cutting tools and grinding wheels, are then precisely engineered and mounted within the machine. Advanced computer numerical control (CNC) systems are often integrated to automate the gear manufacturing workflow and ensure tight tolerances.

Production inputs

The primary inputs for this industry include high-quality steel, carbide, and other durable metallic alloys used to construct the machine bodies and cutting tools. Specialized bearings, motors, and electronic control systems are also essential components. Manufacturers in this industry rely on a skilled workforce capable of operating complex machinery and performing intricate programming and maintenance tasks.

Production outputs

The machines produced under hs code 846140 are used to manufacture gears for a wide range of applications, including 870000 Motor vehicles, tractors, bicycles and other vehicles, 842000 Machinery and mechanical appliances, and 848000 Machinery; parts thereof, not specified or included elsewhere. The precision and efficiency of these gear production machines are critical to the performance and reliability of the end products they support.
