Custom High-Precision CNC Helical Gears – Delivering Exceptional Industrial Transmission Performance

Product Overview
As a leading manufacturer of precision CNC gears, we offer high-end, customized helical gear solutions—spanning the entire process from initial design to mass production. Our helical gears are engineered specifically for demanding applications that require high efficiency, ultra-low noise levels, and extended service life; they serve a wide range of global industries, including automation, speed reducers, and precision machinery.

Core Technological Advantages

Exceptional Smoothness and Low-Noise Operation
Compared to standard spur gears, our precision helical gears feature an optimized helix angle design that ensures smoother engagement during transmission. This not only effectively eliminates transmission vibration but also significantly reduces operational noise levels (decibel output), thereby extending the overall service life of the machinery.

Micron-Level Machining Tolerance Control
Leveraging advanced multi-axis CNC machining centers and precision gear hobbing equipment, we ensure that the geometric accuracy of every gear tooth profile meets rigorous international standards. The coaxiality between the center bore and the shaft axis is controlled to within micron-level tolerances, guaranteeing exceptional stability during high-speed rotation.

High-Strength Materials and Expert Heat Treatment
We support a wide variety of high-performance materials, including 42CrMo alloy steel, SUS304/316 stainless steel, and high-strength engineering plastics. We offer specialized surface hardening treatments—such as induction hardening, carburizing, and nitriding—to ensure that the gear teeth possess exceptional surface hardness and superior fatigue resistance.

Flexible Custom Design Capabilities
Whether you require a single-stage helical gear with an integrated hub or a complex helical gear assembly mounted on a transmission shaft, we can fully customize the number of teeth, module size, and pressure angle to precisely meet your specific torque requirements.
