Description

Shenzhen Jingcheng Dingyi Forming Technology Co., Ltd. is one of the leading manufacturers and suppliers of cnc milling stainless steel parts in China, specialized in providing high quality customized products. If you're going to buy bulk cheap cnc milling stainless steel parts, welcome to get quotation from our factory. Quality products and low price are available.

 

We produce stainless steel parts that need both precision and durability. These are used in industrial machinery, automation systems, and medical equipment where reliability is critical.

Our main materials are 304, 316, and 420 stainless steel:

304 – cost-effective, corrosion-resistant, ideal for brackets and housings.

316 – superior corrosion resistance, perfect for medical or harsh environments.

420 – high hardness and wear resistance, excellent for precision fixtures or shafts.

 

Why Our Milling Stands Out

Tight Tolerances

Critical features held to ±0.005 mm, ensuring perfect fits for assemblies.

Smooth Surfaces

Ra ≤0.4 μm achievable; perfect for contact surfaces, sealing faces, or aesthetic parts.

Durable & Corrosion-Resistant

Passivation and careful machining keep parts lasting even in harsh conditions.

Flexible Production

Prototypes in 3–4 days; small-to-medium batches in under two weeks.

Complex Geometries Handled 3-axis or 5-axis milling lets us handle pockets, slots, and contoured shapes without extra tooling costs.

 

Stainless steel is tricky-heat buildup and work hardening can ruin dimensions or tool life. We manage it with proper cutting speeds, carbide/CBN tooling, and controlled coolant. This keeps parts consistent, batch after batch.

Post-processing includes deburring, polishing, and passivation. For critical applications like medical fittings or automation joints, we check every dimension and surface to ensure reliability.

FAQ

Q1: Which stainless steel grade is best for my milled part?

A1: 304 for cost-effective industrial parts; 316 for medical/harsh environments; 420 for high-hardness fixtures and cutting components.

Q2: What tolerances can you achieve for CNC milled stainless steel parts?

A2: ±0.005mm for critical features (e.g., precision fixtures); ±0.01mm for general milled components.

Q3: What lead times can I expect?

A3: 3–4 working days for 1–5 prototypes; 5–12 working days for 10–500 small-to-high-volume parts.
