CNC Machining Transmission Parts for Automotive and Industrial Gear Systems

CNC Machining Transmission Parts for Automotive and Industrial Gear Systems

Transmission systems are the heart of motion control in vehicles and heavy machinery. Their performance depends heavily on the precision and durability of each internal part. That’s why CNC machining is the preferred process for manufacturing high-performance transmission components.

At HKAA, we manufacture a wide range of CNC machined transmission parts, including:

• Gear shafts

• Synchronizer hubs

• Shift forks

• Transmission cases

• Custom helical gears and sleeves

Using 3- to 5-axis CNC machining, we produce these parts with micron-level accuracy, ensuring optimal performance under high torque, speed, and temperature conditions.

🔧 Why Use CNC Machining for Transmission Parts?

• ✅ Tolerances up to ±0.005mm for gear mesh accuracy

• ✅ High-strength materials: alloy steel, 4140, 4340, stainless steel, aluminum

• ✅ Support for complex geometries (splines, grooves, oil channels)

• ✅ Surface treatments: carburizing, nitriding, black oxide, anodizing

• ✅ Batch repeatability for OEM-grade production

Whether it’s a manual gearbox, EV transmission, or industrial reduction gear, our CNC machining services guarantee the precision and reliability transmission systems require.
