Helical gears operate through the meshing of angled teeth between two gears mounted on parallel shafts. As the driving gear rotates, the inclined teeth engage gradually with the mating gear, allowing multiple teeth to be in contact at the same time. This progressive engagement results in smoother transmission, reduced vibration, and higher load‑carrying capacity compared with spur gears, making helical gears ideal for high‑speed and high‑power applications.

Typical Applications of Custom High Precision Helical Gears
High precision helical gears are widely applied in modern industrial systems where stable and efficient power transmission is required. Typical applications include industrial gearboxes, automotive transmission systems, conveyor equipment, mining machinery, robotics and automation systems, as well as packaging and material handling equipment. Thanks to their smooth operation, durability, and high torque capacity, helical gears have become a key component in many advanced mechanical and manufacturing industries.

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.
