Product Overview

As a leading manufacturer in the industry, we provide high-end CNC turning and turn-mill solutions—ranging from prototype development to mass production.

The product series showcased here encompasses high-speed lightweight drums, large-diameter positioning baseplates, and titanium-coated precision pins. These examples demonstrate our exceptional expertise in machining materials such as aerospace-grade aluminum (7075), stainless steel (316L), brass, and alloy steels. Whether you require a baseplate with ultra-high flatness for a semiconductor vacuum environment or a high-strength rotor for a robotic joint, we are capable of delivering precision-customized components that meet micron-level tolerance requirements.

Core Technical Advantages

High-Precision Multi-Axis Turn-Mill Capabilities
We utilize advanced 5-axis simultaneous CNC lathes capable of completing complex operations—including turning, drilling, slotting, and back-side machining—in a single setup. This ensures exceptional concentricity and positional accuracy, with critical tolerances consistently maintained within ±0.005 mm.

Dynamic Balancing Optimization for High-Speed Rotating Components
For components such as centrifuge rotors or motor flywheels, we employ precise structural lightweighting designs and rigorous pre-shipment balancing adjustments. This ensures that the equipment operates smoothly and with minimal noise, even at high rotational speeds (exceeding 20,000 RPM).

Semiconductor-Grade Surface Finish and Cleanliness
We provide ultra-high flatness control for large-diameter baseplates and offer various surface treatments, including hard anodizing, electroless nickel plating, and wear-resistant titanium coating. Our products meet strict cleanroom standards and are widely utilized in manufacturing equipment by world-renowned semiconductor companies.

Digital Quality Tracking and Traceability
Every precision component undergoes rigorous inspection using a Coordinate Measuring Machine (CMM). Furthermore, upon customer request, we can apply laser-etched traceability markings to the component edges, ensuring full transparency and quality assurance throughout the entire production process.
