Precision Gear Machining Services with CNC Technology

Gears are essential components in power transmission systems. Whether used in automotive gearboxes, aerospace actuators, or industrial reducers, they require high accuracy, perfect tooth profile, and stable performance under load. That’s why CNC machining is the preferred solution for modern gear manufacturing.

At HKAA, we offer gear machining services using advanced CNC turning, milling, and hobbing equipment. We produce a wide variety of custom gears, including:

• Spur Gears

• Helical Gears

• Bevel Gears

• Worm Gears

• Internal Gears

Our factory supports materials such as alloy steel, stainless steel, brass, aluminum, and nylon, meeting diverse mechanical and environmental needs.

✅ Case Study: Custom Helical Gears for a German Automotive Client

In 2024, HKAA collaborated with a well-known German manufacturer of high-performance automotive transmissions to produce a batch of precision helical gears for their latest dual-clutch system.

Project Specifications:

• Material: 20CrMnTi alloy steel (carburized)

• Precision Standard: DIN 6

• Surface Hardness: HRC58–62

• Process: CNC rough machining → gear hobbing → gear grinding

• Quality Control: 100% inspection with gear measuring machine, CMM, and hardness testers

We applied 5-axis CNC machining and precision grinding, completing the prototype within two weeks. The first samples passed assembly and performance testing at the client’s German facility. These gears were later included in their mass production lineup, and to date, we have supplied over 80,000 pieces with a 99.98% qualified rate.

This case proves HKAA’s capacity for delivering high-precision gear machining services with international-grade quality and consistency.
