High-Accuracy Motion Conversion Elements

Precision spur gears are essential components for converting rotary motion into precise movement in industrial equipment. These gears are widely used in instruments, robotics, and high-precision machine tools. Our precision spur gears combine compact sizes with excellent profile accuracy. We understand that roundness and tooth surface quality are critical indicators of gear performance. That is why we focus on achieving stable accuracy and consistent quality for every gear we manufacture.

Exceptional Roundness and Smooth Tooth Surfaces

For our miniature precision spur gears, we achieve Grade 5 precision. This means roundness error remains within ≤0.004 mm. The tooth surface roughness reaches Ra 0.2 μm, providing an ultra-smooth surface finish. This low-friction surface helps reduce energy loss and extend gear service life. For larger gears, we guarantee Grade 7 precision with Ra 0.8 μm tooth surface requirements. This focus on profile accuracy and surface quality helps our customers achieve reliable performance in demanding applications.

Specialized Equipment for Micro Precision Parts

Our strength lies in machining ultra-small and high-precision components. Our Tsugami S206A and Citizen A20N Swiss-type automatic lathes specialize in processing Φ3 mm-level miniature shafts and gear components. We also use digital production management tools to optimize scheduling and quality control. Our entire team follows the "Three No" quality principle: we do not produce, accept, or release defective products. Through first-article inspections and regular in-process checks, we maintain stable production quality. Our precision spur gears support demanding applications in industries such as medical equipment and semiconductor manufacturing.

Customer-Focused Service Approach

Our service model focuses on providing efficient solutions for customer requirements. From your first inquiry, we assign a dedicated project coordinator to manage communication. This person coordinates technology, production, quality inspection, and logistics. We understand that prototype development during R&D stages often requires quick response. Therefore, we provide rapid prototyping support for new projects. For established customers, we offer sample production for testing and verification. We also provide flexible trade terms including EXW, FOB, and DDP according to delivery requirements.
