Strong and Corrosion-Resistant Precision Parts
Stainless steel CNC machining parts are widely used in food machinery, marine equipment, and outdoor gear. Our product are made from 304 stainless steel. This material offers excellent corrosion resistance and high strength. We use CNC turning and CNC milling for precision machining. Features such as drilling, tapping, slotting, step machining, and countersinking can be completed in a single setup. General assembly parts can achieve dimensional tolerances of ±0.03 to ±0.05 mm. Precision fitting areas can achieve tolerances of ±0.01 to ±0.02 mm. Surface roughness for non-fitting appearance surfaces is Ra 3.2 μm. Assembly reference surfaces are Ra 1.6 μm. Sliding friction surfaces are Ra 0.8 μm.
Advanced Machining and Passivation Treatment
Our Haas CNC machining centers and CMM machines ensure high precision and consistency for these stainless steel CNC machining parts. Surface treatments include brushing, polishing, and passivation. Passivation is an important process for improving corrosion resistance. We apply passivation to every batch of stainless steel parts. Our factory holds ISO 9001 certification. Our products comply with applicable environmental regulations. We have a dedicated quality team that inspects every batch. We also support third-party inspections.

Global Reach and Reliable Service
We offer a one-year warranty on these stainless steel CNC machining parts. If goods arrive damaged, we help with the insurance claim. Our sales network covers more than 30 provinces in China. We also export to Europe, North America, and Southeast Asia. Our MOQ is one unit. We accept small trial orders. Standard products ship within one week. Custom products require 15 to 30 days. We support EXW, FOB, and DDP trade terms. We accept payments in both RMB and USD. We look forward to building a long-term relationship with you.
