Lapped spiral gears are precision-finished through an advanced lapping process that removes microscopic irregularities from the tooth surfaces. This meticulous finishing technique ensures optimal gear meshing, significantly reduced noise levels, and enhanced surface contact between mating gears, resulting in superior performance and extended service life.

Custom High Precision Lapped Spiral Gear Typical Applications
Lapped spiral gears are essential components in applications requiring smooth, quiet operation and high precision, including:
- High-speed precision gearboxes
- Aerospace and aviation systems
- Medical equipment and surgical robots
- High-performance automotive drivetrains
- Precision machine tools and CNC machinery
- Marine propulsion systems
The superior surface finish and precise tooth geometry achieved through lapping make these gears ideal for demanding applications where noise reduction, efficiency, and reliability are critical factors in modern power transmission systems.

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 Milling
Gear Milling is a gear cutting process that used a rotating from cutter shaped to match the exact space between two gear teeth is plunged into the gear blank. After cutting one tooth space, the blank is indexed to the next position .
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 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.
CNC Machining
CNC machining is a an automated manufacturing process controlled by pre-programmed computer software and code. Normally gears are designed in CAD software. CAM software translates the CAD model into G-Code, a machine language that dictates tools paths, speeds, feeds, and all movements.
Gear Lapping
Gear lapping is a process for for finishing hardened bevel gears under gleason profile. This process can greatly improve surface finish and noise, however which could not correct geometric errors. It’s often done in paired sets (gears are lapped together and must remain matched). That is usual to use in high-volume bevel gears, where quiet operation is paramount.
Marking
Precision laser marking permanently engraves traceability data (part numbers, date codes, logos) onto gears, ensuring reliable identification and quality tracking throughout the product lifecycle.
Clean & Package
Before shipment, every gear is carefully cleaned, dried, and rust-protected – ensuring they arrive in optimal condition, ready for immediate installation.
