Gear manufacturing refers to the design, production, and finishing of gears that transmit motion and power within mechanical systems. The process includes key stages such as material selection, cutting and forming, heat treatment, and precision finishing to ensure accurate tooth geometry and long service life. Common techniques include hobbing, milling, shaping, broaching, grinding, and forging. The use of advanced CNC machinery and stringent quality control ensures high accuracy, strength, and reliability. Gears play a vital role in automotive applications, industrial equipment, aerospace systems, consumer electronics, and power transmission, making gear manufacturing a cornerstone of modern mechanical engineering.
