The working principle of a spur gear is based on the meshing of gear teeth. When one gear (the driving gear) rotates, its teeth engage with the teeth of the mating gear (the driven gear). As the teeth mesh, rotational motion and torque are transferred from the driving gear to the driven gear. The speed ratio between the gears is determined by the number of teeth on each gear.

Applications of Spur Gears
Spur gears are widely used in a variety of industrial and mechanical systems where efficient power transmission between parallel shafts is required.
Common applications include:
- Industrial Gearboxes: Spur gears are frequently used in industrial gearboxes to transfer power between shafts while maintaining precise speed ratios and reliable torque transmission.
- Automation and Robotics Equipment: In robotic systems and automated machinery, spur gears help achieve accurate motion control and reliable mechanical synchronization.
- Machine Tools: Many machine tools utilize spur gears to drive components such as feed mechanisms, lead screws, and spindle systems.
- Conveyor Systems: Spur gears are commonly applied in conveyor drives to deliver stable and consistent motion in manufacturing and material handling systems.
- Agricultural and Construction Machinery: Heavy duty spur gears are used in tractors, harvesters, and construction equipment to transmit torque efficiently under demanding operating conditions.

Forging
When gears need high performance that needs to withstand high loads, high stress, impact loads or fatigue loads, forgings are suggested to use. Forging allows metal fibers to be continuously distributed along the gear profile, significantly improving root strength and fatigue life.
Turning
This is the process of cutting and shaping solid materials into precise parts. It uses tools like lathes, mills, and drills to remove excess material. Machining transforms a simple block of metal into a finished, functional component.
Gear Cutting
Gear Cutting includes all processes to create gear teeth after rough or fine machining. It shapes teeth to ensure smooth and efficient power transfer for performance, strength and cost efficiency.
Heat Treatment
Gears need to be running with two gears or above two gears, that makes them easy to be worn-out. That’s why most types of gears need to be harden through heat treatment.
ID & OD & Surface Grinding
ID grinding, OD grinding, Surface grinding are all belonging to CNC grinding which are the foundational precision abrasive machining processes used to achieve exceptional dimensional accuracy and surface finishes, especially on hardened materials.
Tooth Grinding
Tooth Grinding are the final processes are applied after heat treatment to correct distortion, improve geometry, and achieve the final surface finish necessary for quiet, efficient power transmission.
