We manufacture helical gears from module 0.5 to 16, with particular expertise in small modules and low tooth counts. Made from alloy steel or stainless steel, each gear goes through precision hobbing and heat treatment to achieve consistent tooth geometry and surface hardness.

Manufacturing Accuracy
Our CNC gear cutting and measurement systems maintain tooth profile accuracy within 0.01 mm and lead accuracy within 0.015 mm. Full custom design is supported from client drawings, including tooth profile optimization and modification to reduce vibration and wear.

Key Performance Data

• Noise Reduction: Helical engagement lowers operating noise by 30–40% compared to spur gears of similar size.

• Load Capacity: Case?hardened teeth achieve 55–60 HRC surface hardness.

• Transmission Accuracy: Tight tolerances ensure minimal positional error in precision drives.

• Temperature Range: Suitable for –40°C to 120°C with proper lubrication.

Typical Applications

• Servo motors and robotic joints

• Medical and optical instruments

• CNC spindles, rotary tables, and indexers

• Automated positioning and conveying systems

Quality Assurance
Each batch undergoes material verification, hardness testing, dimensional inspection, and noise validation under load. Our process follows ISO 9001 standards to ensure consistent field performance.
