Product Overview

As a leading manufacturer in the field of precision CNC machining, we are dedicated to providing global technology enterprises with the most demanding **CNC Turning** and turn-milling services.

The series of parts showcased here encompasses a diverse range of forms—from high-speed rotating drums to large-scale precision baseplates—demonstrating our cutting-edge machining capabilities across stainless steel, high-strength aluminum alloys, and alloy steels. Whether for the agile transmission systems of robotic joints or the exacting micron-level tolerance requirements of semiconductor production lines, our custom-engineered components deliver exceptional reliability and stability.

Core Technical Advantages

Ultra-High Precision Multi-Axis Machining
We are equipped with advanced 5-axis simultaneous CNC lathes capable of completing turning, drilling, slotting, and back-side machining operations for complex shaft and disc-shaped parts in a single setup. This approach eliminates fixturing errors at the source, ensuring that the coaxiality and positional accuracy of our parts remain within a tolerance of ±0.005 mm.

Dynamic Balancing & Lightweighting Optimization
For high-speed rotating assemblies, we provide expert recommendations for structural lightweighting. Through precisely calculated weight-reduction hole patterns and rigorous dynamic balancing adjustments prior to shipment, we ensure that our components maintain zero vibration and achieve extended service life even under high-speed operating conditions.

Rigorous Material Selection & Surface Treatment

Material Coverage: Includes 304/316L stainless steel, 7075-T6 aerospace-grade aluminum, 40Cr heat-treated alloy steel, and more.
Post-Processing: We offer hard anodizing, electroless nickel plating, passivation, and precision grinding services to meet the stringent standards required for Cleanroom environments, as well as the
corrosion resistance demands of harsh industrial settings.

100% Digital Quality Control
Every precision component undergoes rigorous inspection using CMM (Coordinate Measuring Machines), optical projectors, and laser surface roughness testers. This comprehensive verification process ensures that the final product matches your CAD specifications with zero deviation.
