CNC Machining and Black Oxide Finishing for 1020 Steel Automation Module Components
CNC Machining of Automation Components: Durable and Economical Solutions for Modular Systems
Automation module components are critical for precise positioning, structural integration, and motion transfer within high-efficiency systems. These parts must meet tight dimensional tolerances, provide surface protection, and maintain mechanical reliability under continuous operation. At Neway, we specialize in CNC machining and precision machining of 1020 carbon steel for automation systems, delivering robust, dimensionally accurate components tailored to custom modular assemblies.
Post-machining, we apply sandblasting and black oxide coating to enhance corrosion resistance, surface uniformity, and appearance.
Why 1020 Steel Is Ideal for Automation Module Components
Balanced Mechanical Properties and Machinability
1020 steel is a low-carbon alloy with good toughness, machinability, and weldability. With tensile strength around 410–510 MPa and excellent dimensional stability during cutting, it is ideal for brackets, frames, supports, and actuator housings used in automated assemblies.
Cost-Effective for High-Volume Applications
Its affordability and process compatibility make 1020 steel an optimal choice for repeatable part geometries in automation lines where cost-per-unit and reliable performance are key.
CNC and Precision Machining for Automation Modules
Machining for Structural Accuracy and Functional Interfaces
Our machining process covers all essential features for automation integration:
Flatness: ≤ 0.01 mm on mounting surfaces
Hole position tolerance: ±0.02 mm for dowels and fasteners
Surface finish: Ra ≤ 1.6 µm for sliding or contact areas
Precision CNC machining ensures proper alignment with mating components, sensors, and fixtures in modular automation setups.
Tight Tolerance Control and Repeatability
Using high-speed mills and coordinate fixtures, we maintain high consistency for parts that require:
Symmetric slotting or grooving
Tap holes with thread depth control
Frame cutouts with ±0.05 mm dimensional stability
Surface Treatment: Sandblasting and Black Oxide
Sandblasting for Surface Cleanliness and Pre-Coating Texture
Sandblasting removes residual scale and improves adhesion of post-treatments. It ensures a uniform, matte surface texture that visually enhances modules and prepares them for coating.
Black Oxide for Corrosion Protection and Aesthetic Finish
Our black oxide treatment is performed in controlled immersion baths to meet automation-grade standards:
Corrosion resistance in indoor and low-moisture environments
Anti-glare surface ideal for sensor-heavy automation spaces
Minimal dimensional change (<1 µm), preserving machining tolerances
Quality Control and Reporting
CMM inspection of critical fits and flatness
Visual and thickness inspection post-black oxide
Surface finish measurement with profilometers
Material certificate, coating compliance reports, COC available
