Steel in CNC Machining
At Tuowei Precision, our CNC steel machining services handle everything from rapid functional prototypes to high-volume production components. Because carbon and alloy steels are susceptible to surface oxidation, we provide integrated post-processing—including black oxide, zinc plating, carburizing, and heat treatments—to ensure optimal environmental protection and long-term mechanical reliability.

Steel CNC Machining Materials
Steel Material Properties
Copper C103 provides high electrical conductivity with good formability and reliable machining performance. It is commonly used for connectors, terminals, electronic components, and applications that require efficient current flow.

High Electrical Conductivity: Provides low electrical resistance and minimal power loss, ensuring optimal current transfer for terminals, connectors, and busbars.
High Thermal Conductivity: Efficiently dissipates heat away from critical assemblies, making it the preferred choice for heat sinks, cooling plates, and heat exchangers.
耐食性： Naturally develops a protective surface oxide layer that shields parts from atmospheric oxidation, water exposure, and industrial chemicals.
Malleability and Ductility: High material flexibility enables smooth cold forming and the machining of intricate, detailed features without brittle fracturing.
Antimicrobial & Biostatic Properties: Inhibits bacterial proliferation and microbial buildup, making it exceptionally reliable for healthcare equipment, laboratory instruments, and sanitary systems.
耐久性がある： Offers long-term structural integrity and resistance to operational fatigue, lowering maintenance downtime and replacement costs.
- Risk of Corrosion:
Some steel grades can rust or corrode without proper surface treatment, coating, or protective finishing. - Higher Weight:
Steel is heavier than materials such as aluminum, which may not suit applications where low weight is a priority. - Increased Tool Wear:
Harder steel grades can wear cutting tools faster and may require slower machining speeds and more frequent tool replacement.
- Longer Machining Time:
High-strength steels can take more time to cut and finish, especially when tight tolerances or complex geometries are required.

Steel CNC Machining FAQs
Can you machine both small and large steel parts?
Yes. Our steel CNC machining service can produce both small precision components and larger industrial parts. We select the right machining process based on the part size, geometry, tolerance, and production requirements.
What tolerances can you achieve with steel CNC machining?
We can machine steel parts to tight tolerances based on the design, steel grade, and part complexity. For demanding applications, we can also support precision features that require consistent dimensional accuracy.
Is steel CNC machining more expensive than machining aluminum?
Steel can cost more to machine than aluminum because it is harder and may require slower cutting speeds and greater tool wear. However, the final cost depends on the steel grade, part geometry, tolerances, quantity, and surface finish requirements.
