CNC Machining Gears with Precision and Consistency

CNC Machining Gears with Precision and Consistency

Gears are critical to nearly every mechanical transmission system. Whether in automotive gearboxes, industrial robotics, or aerospace mechanisms, the reliability of a gear depends entirely on its precision, material integrity, and machining consistency. That’s why HKAA provides high-precision CNC machining services for gears of all types.

We specialize in the production of:

• Spur gears

• Helical gears

• Bevel gears

• Internal gears

• Shaft-integrated gear components

Using CNC turning, milling, hobbing, shaping, and grinding, we produce gears that meet strict tolerances and ensure smooth, quiet, and durable performance — even in high-load or high-speed environments.

🔧 Our Gear Machining Capabilities

• ✅ Gear types: spur, helical, bevel, internal, spline

• ✅ Material options: 20CrMnTi, SCM415, stainless steel, aluminum, brass

• ✅ Precision: DIN 6–8 grade, ±0.01mm concentricity

• ✅ Heat treatment: carburizing, quenching, nitriding for long wear life

• ✅ Surface finishing: black oxide, phosphate, anodizing, polishing

• ✅ QC tools: Zeiss CMM, gear profile projector, hardness tester

Each gear is subject to 100% dimensional and profile inspection, ensuring optimal meshing performance and lifespan.

✅ Case Study: CNC-Machined Helical Gear for Conveyor Application

In 2024, HKAA worked with an Italian automation integrator to deliver a batch of precision helical gears used in a servo-driven conveyor line.

Project Details:

• 📌 Material: 20CrMnTi alloy steel

• 🔍 Diameter: 95mm, module: M2.5

• 🎯 Tolerance: DIN 6

• 🔥 Heat Treatment: Carburized to HRC58–62

• ⚙️ Finish: Gear grinding + phosphate coating

• 📦 Order volume: 10,000 pcs/year

The client needed ultra-quiet performance and consistent torque transfer in 24/7 working conditions. Our CNC-machined gears passed vibration and wear testing with flying colors, leading to long-term partnership and multiple reorder cycles.
